Program to Find the Size of int - (C Programs)

Example

#include <stdio.h>

int main() {
    int n;
    printf("Size of Integer: %d bytes", sizeof(n));
    return 0;
}

Output

Size of Integer: 4 bytes

Explanation

The sizeof operator in C language is used to determine the size of a variable or data type. In the above program, we have declared an integer variable n and used the sizeof operator to get the size of the integer data type. The size of int data type in C language is 4 bytes. Therefore, the output of the program is Size of Integer: 4 bytes.

Use

This program is useful when we need to determine the size of int data type in a C program. The output of this program can be used by other programs that need to allocate memory for integer variables.

Summary

In this C program, we have used the sizeof operator to determine the size of int data type. The size of int data type in C language is 4 bytes. This program is useful for determining the size of int data type in C programs.
