Explanation:

The programming language, compiler, and system architecture (e.g., 32-bit or 64-bit) all affect the size of data types.

Different programming language offers different size ot same data type. For example, in C, integer is of 2 bytes where as its 4 byte in C#.

Program to print size of various data types

#include <stdio.h>

    printf("Size of float: %zu bytes\n", sizeof(float));
    printf("Size of double: %zu bytes\n", sizeof(double));
    printf("Size of char: %zu bytes\n", sizeof(char));
    printf("Size of long: %zu bytes\n", sizeof(long));
    return 0;
