#include <stdio.h> int main() { unsigned char x=300; printf("%d",x); }

Question

Anyone please explain me the concept of unsigned

Answer 1

unsigned char datatype range from 0 to 256. So, when you want to initialized 300, it takes it (300-256)=44.
That's why the result is 44

Answer 2

Also after reading other answers, run this code.
You will get it what happens.

#include <iostream>
using namespace std;

int main() {
int i = 200;
for(unsigned char c = 200; c < 350; c++)
cout << "int: " << i++ << ", unsigned char: " << (int)c << "\n";
return 0;
}

Answer 3

Generally data types goes from negative A-1 to positive A.
Unsigned free up first bit that is used for sign and doubles range of positive values.
for example if a Data type can take values from -127 to 128.
An unsigned Data type will go from 0 to 256.
