This C program shows that how you can print size of any data type available in C language. To find size of any data type, C has one special operator sizeof. It simply calculates and returns the size of any given data type in bytes.

Program

SizeOfDataTypes.CCopy
#include <stdio.h>

int main() {

    printf("Type          Size (bytes)\n");
    printf("Characte      %d\n", sizeof(char));
    printf("Integer       %d\n", sizeof(int));
    printf("Long int      %d\n", sizeof(long int));
    printf("Float         %d\n", sizeof(float));
    printf("Double        %d\n", sizeof(double));
    printf("Long double   %d", sizeof(long double));

    return 0;
}
Try It

Output
