C program to find the size of variables

 In this example, discuss how to find the size of the variable in c programming language. Following is the code of the problem.

Code:

#include<stdio.h>

int main() {

    int intvar;

    float floatvar;

    double doublevar;

    char charvar;


    // sizeof is used to find the size of a variable

     printf("Size of char: %zu byte\n", sizeof(charvar));

    printf("Size of int: %zu bytes\n", sizeof(intvar));

    printf("Size of double: %zu bytes\n", sizeof(doublevar));

    printf("Size of float: %zu bytes\n", sizeof(floatvar));

     

    

    return 0;

}

Output:

Size of char: 1 byte

Size of int: 4 bytes

Size of double: 8 bytes

Size of float: 4 bytes
