Can someone explain me what is the difference between ++a and a++?

Question

#include <iostream>
using namespace std;

int main() {
int a=1;
int b=1;

b++;
++a;

cout<<a<<" , "<<b;
return 0;
}

Answer 1

Luis
In your code b++ means adding 1 to your variable b, and ++a means adding 1 to both a and b and have the same value of a and b.

Answer 2

a++ takes the variable and adds to it. ++a takes the variable, adds to it, then makes that new value the value of the variable.
