What is Array in C Programming?

What is an array in C. An array is a kind of data structure, array is a collection of data that stores fixed number of values of same type. For example: if you want to store some numbers, you can create an array for it and store.

Array Syntax:

int number[10];

Once you declare the array size and array type, you cannot be changed.

Types of Arrays:

There are two types of arrays in C programming.

1. Onedimensional arrays
2. Multidimensional arrays

Arrays Declarations And Initialization

Arrays Declaration:

datatype arrayname[array size];

Array Example:

int numbers[5];

Here numbers array can hold 5 integer elements, in each field of numbers[0], numbers[1], numbers[2], numbers[3], numbers[4].

Initializing Arrays Elements:

Here are the different ways of initializing array elements:

1. int numbers[5] = {5,10,15,20,25};
2. int numbres[] = {5,10,15,20,25};

How elements stored in array

mark[0] is equal to 5
mark[1] is equal to 10
mark[2] is equal to 15
mark[3] is equal to 20
mark[4] is equal to 25

C Array Program Example

Learn how to write a  program for array in c. Writing an array program in C can be done using various techniques but here in this program, we show how to write a arrays program in c in a proper way. Happy coding.

C Program Array Source Code

You can copy paste the below array program in c compiler to check how the source code work. Or write your own array C Program with the help of this below c program for array.

/* C PROGRAM ARRAY - ARRAYEXAMPLE.C */

// C Program Array to find the average of the numbers 

#include <stdio.h>
int main()
{
 
//Array declaration
 int marks[10], i, n, sum = 0, average;
 printf("Enter n: "); //Asking user to enter number array size
 scanf("%d", &n); //Reading array elements
 for(i=0; i<n; ++i)
 {
 printf("Enter number%d: ",i+1); //Asking user to enter array elements 
 scanf("%d", &marks[i]); //Reading array elements
 sum += marks[i];
 }
 average = sum/n;

printf("Average = %d", average); //Printing output

return 0;
}

C PROGRAM Array – OUTPUT

After you compile and run the above c program array, your C compiler asks you to enter elements for the array to perform the average. After you enter elements, the program will be executed and give output.

Output:

Enter n: 5

Enter number1: 10

Enter number2: 15

Enter number3: 20

Enter number4: 25

Enter number5: 30

Average = 20
