Write a C program to find size of variables using sizeof() operator

Below is the source code for C program to find size of variables using sizeof() operator which is successfully compiled and run on Windows System to produce desired output as shown below :

SOURCE CODE : :

/*  C program to find size of variables using sizeof() operator  */

#include <stdio.h>

int main()
{

    char    a       ='Z';
    int     b       =45;
    float   c       =345.0f;
    double  d       =7654.90;
    char    str[]   ="Codezclub";

    printf("Size of a: %d\n",sizeof(a));
    printf("\nSize of b: %d\n",sizeof(b));
    printf("\nSize of c: %d\n",sizeof(c));
    printf("\nSize of d: %d\n",sizeof(d));
    printf("\nSize of str: %d\n",sizeof(str));

    return 0;
}

OUTPUT : :

/*  C program to find size of variables using sizeof () operator  */

Size of a: 1

Size of b: 4

Size of c: 4

Size of d: 8

Size of str: 10

Above is the source code for C program to find size of variables using sizeof () operator which is successfully compiled and run on Windows System.The Output of the program is shown above .
