C Program to find size of int, float, double, and char

Through this tutorial, i am going to show you how to find the size of int, float, double and chart data types in c programs.

Using the sizeof(variable)operator with %lu or %zu format specifier, you can find the size of int, float, double and char data types.

C Program to find size of int, float, double, and char

#include<stdio.h>
int main() {
    int intType;
    float floatType;
    double doubleType;
    char charType;
    // sizeof evaluates the size of a variable
    printf("Size of int: %zu bytes\n", sizeof(intType));
    printf("Size of float: %zu bytes\n", sizeof(floatType));
    printf("Size of double: %zu bytes\n", sizeof(doubleType));
    printf("Size of char: %zu byte\n", sizeof(charType));
    
    return 0;
}

The output of the above c program; as follows:

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