This program declares 4 variables of type int, float, double and char. Then, the size of each variable is evaluated using sizeof operator.

Program to Find the Size of int, float, double and char

#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;
}

Output

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

In this program, 4 variables integerType, floatType, doubleType and charType are declared having int, float, double and char type respectively. Then, the size of each variable is ascertained using sizeof operator.
