# Type difference of character literals in C vs C++

C++Server Side ProgrammingProgramming

In C++ the size of the character constants is char. In C the type of character constant is integer (int). So in C the sizeof(‘a’) is 4 for 32bit architecture, and CHAR_BIT is 8. But the sizeof(char) is one byte for both C and C++.

## Example

#include<stdio.h>
main() {
printf("%d", sizeof('a'));
}

## Output

4

## Example

#include<iostream>
using namespace std;
main(){
cout << sizeof('a');
}

## Output

1

In both cases we are doing the same. But in C sizeof(‘a’) returns 4 as it is treated as integer. But in C++ it is returning 1. It is treated as character.
