c program to print the size of various data types


#include <stdio.h>
int main()
    int integerType;
    float floatType;
    double doubleType;
    char charType;

    // Sizeof operator is used to evaluate the size of a variable
    printf("Size of int: %ld bytes\n",sizeof(integerType));
    printf("Size of float: %ld bytes\n",sizeof(floatType));
    printf("Size of double: %ld bytes\n",sizeof(doubleType));
    printf("Size of char: %ld byte\n",sizeof(charType));

    return 0;


Size of int: 4 bytes
Size of float: 4 bytes
Size of double: 8 bytes
Size of char: 1 byte
