C Program to Implement Stack using array. C Programming Server Side Programming. A stack is an abstract data structure that contains a collection of elements. Stack implements the LIFO mechanism i.e. The element that is pushed at the end is popped out first. Some of the principle operations in the stack are −. C Arrays - An array is a one of the data structure in C, that can store a fixed size sequential collection of elements of same data type.

Aug 16, 2018 Penjelasan: Dalam contoh program array C sederhana di atas, Anda dapat mendeklarasikan variabel x dan y sebagai iterator. Lalu Anda mendeklarasikan varibel “tabel” dengan tipe array dua dimensi, dimana dapat diibaratkan sebuah tabel dengan jumlah baris = 3 dan jumlah kolom = 5. Mar 21, 2019 Dalam program diatas, saya ingin menjumlahkan nilai dari tiap index umur dan hasilnya saya simpan kedalam variabel hasil untuk ditampilkan di akhir program. #2 Contoh Program C Array 2 Dimensi. Sama halnya dengan array 1 dimensi, array 2 dimensi juga memiliki cara yang sama dalam pendeklarasiannya. Berikut contoh array berdimensi 2. To solve this problem in C, you can create an integer array having 100 elements. An array is a collection of data that holds fixed number of values of same type. For example: int age100; Here, the age array can hold maximum of 100 elements of integer type. The size and type of arrays cannot be changed after its declaration.

C++ provides a data structure, the array, which stores a fixed-size sequential collection of elements of the same type. An array is used to store a collection of data, but it is often more useful to think of an array as a collection of variables of the same type.

Instead of declaring individual variables, such as number0, number1, ..., and number99, you declare one array variable such as numbers and use numbers[0], numbers[1], and ..., numbers[99] to represent individual variables. A specific element in an array is accessed by an index.

All arrays consist of contiguous memory locations. The lowest address corresponds to the first element and the highest address to the last element.

Declaring Arrays

To declare an array in C++, the programmer specifies the type of the elements and the number of elements required by an array as follows −

This is called a single-dimension array. The arraySize must be an integer constant greater than zero and type can be any valid C++ data type. For example, to declare a 10-element array called balance of type double,use this statement −

Initializing Arrays

You can initialize C++ array elements either one by one or using a single statement as follows −

The number of values between braces { } can not be larger than the number of elements that we declare for the array between square brackets [ ]. Following is an example to assign a single element of the array −

If you omit the size of the array, an array just big enough to hold the initialization is created. Therefore, if you write −

You will create exactly the same array as you did in the previous example.

The above statement assigns element number 5^th in the array a value of 50.0. Array with 4^th index will be 5^th, i.e., last element because all arrays have 0 as the index of their first element which is also called base index. Following is the pictorial representaion of the same array we discussed above −

Accessing Array Elements

An element is accessed by indexing the array name. This is done by placing the index of the element within square brackets after the name of the array. For example −

The above statement will take 10^th element from the array and assign the value to salary variable. Following is an example, which will use all the above-mentioned three concepts viz. declaration, assignment and accessing arrays −

This program makes use of setw() function to format the output. When the above code is compiled and executed, it produces the following result −

Arrays in C++

Arrays are important to C++ and should need lots of more detail. There are following few important concepts, which should be clear to a C++ programmer −

Arrays, in C++, are simply arrangements of 'objects' -- in the basic usage we'll be using in this tutorial, we will be using arrays to simply store lists of data (of a certain because each piece of data stored (whether it be an integer, string, or something entirely different) has a number assigned to it that it can be referenced by. This is called the index, and the index number simply counts up from 0 as the array gets bigger - so the first element in the array would have the index of 0, the second the index of 1, etc.

Obviously storing data in this tabular-like manor is very useful in real world applications - a classic example that is usually given is pupils' scores in a test. Perhaps each student got a score out of 100 for their test - this data would be best stored in an integer array. In the real world the scores would probably be recorded in a text file or something similar, but we could always build in functionality to read this file and then store that data in an array inside our application.

Arrays can be created in C++ very much like 'normal variables' (with a) , followed by the index number of the element we wish to target in square brackets, followed by an equals sign and then the value we wish to set it to (and then obviously a semi-colon to end the line). So if we wanted to initialize the first element (of index 0) in our array to the value '15', we could write the following:

The same could also be done for the scores of the other members of the class (elements of the array from index 0 to index 29). If we then wanted to use these values later (for example if we wanted to cout one or all of the elements), we can access a certain element of the array just as we did when we were assigning values to each element - by writing the array name and then the index number in square brackets. So we could output the first element in the array (remember, this is the one with the index of 0!) by writing something like cout << ClassScores[0];.

You may have noticed when we learnt how to initialize the elements in arrays earlier, that the process was extremely long and drawn out (imagine having to initialize hundreds of array elements!) - luckily there is an easier way to initialize the elements in an array. Instead of individually setting each element to a certain value (which can be done at any point in the program, not just at element initialization) we can actually initialize the elements when we declare the array! This method of initialization is accomplished by simply shoving an equals sign after the declaration of the array and then specifying the different array elements, with commas separating them, in curly brackets. This method doesn't require any value in the square brackets either as the compiler can calculate how many elements we are initializing and set the array size to that! To show this method of initialization, let's just set some values for each score in the class at the array declaration - let's cut it down to 20 this time for the sake of simplicity:

With an array declared and initialized, we can do a whole bunch of stuff with it! A nice example might be outputting all of the students' scores - unfortunately, however, there's no really easy and clean way to do this without knowing about 'loops' or some other fancy things, so for now we'll have to just repeat a bunch of code. Generally speaking when you feel your repeating a lot of code when C++ programming, there is probably a better way to accomplish what you're trying to do, but for now just go with it. I've cut the array down to 5 elements this time, simply because I don't want to have to copy and paste a single line 20 times - you'll learn about a more elegant solution to our problem of outputting array elements in the next tutorial.

Another really cool thing that you could do with arrays is trying to 're-create' the 'string', character arrays like 'H', 'e', 'l', 'l', 'o' were used -- character arrays of this kind can, unlike most, actually be outputted just by couting their name because they're so much like strings. It's worth nothing that when creating character arrays like these, however, you should also add another character onto the array, which is a 'null character' which shows where the string ends - this is called the null termination of a string, and the null character is expressed via '0'.

'Real' strings can actually be treated just like character arrays in some circumstances too - using square brackets and an index number gets a certain character of the string (for example string_name[1] of 'Hello' would be 'e'). If you're feeling up to the challenge, try moving a string variable defined in code (of a fixed length) like string one = 'Hello';, to a 'char' array of the same length using the information above. It probably seems a bit pointless, I know, but it's good practice with using arrays. If you don't feel up to the challenge, the code for doing such a thing (which once again would be a bit cleaner with 'loops'), is as follows:
