About this program

This is an example program in c array example programs. Read the concept first: C Array, then study the code and output below.

Definition

An array is a collection of data that holds homogeneous values. That means values should be in same type

Array Syntax

type variable_name[size]

Sizeof Syntax

sizeof(data_type)

Simple C Program for Find Array Size

/*## Simple C Program for Find Array Size */
/*## Simple Array Programs,Find Array Size C Programming, sizeof Example*/

#include <stdio.h>
 
int main() {

	// Declare Array Variable
    int array[5]= { 1, 2, 3, 4, 5 };
    
    //Read Day Value
	int size;
	
	size = sizeof(array)/sizeof(int);

    //Print size of Array
    printf("The Size of Array is %d", size);
    
   
	return 0;
}

Sample Output:

The Size of Array is 5

How It Works

This C program demonstrates Simple C Program for Find Array Size. It first prepares the data it needs, then performs the core operation step by step, and finally prints the output shown in the Sample Output above.

  1. Declare the variables that hold the program’s data.
  2. Print the final result to the console so you can compare it with the sample output.

Try changing the input values and re-running the program to see how the output changes — this is the fastest way to understand how the logic behaves.
