Question

#include <iostream>
using namespace std;

int main() {
int x=1;
if(x>0)
cout<<"positive number"<<endl;
else
cout<<"negative number";

return 0;
}

Answer 1

You only need to use brackets if it's more than one line. You only used one line in this case, so it works.

Answer 2

Curly brackets are only required if you want to put more than only one instruction in the block...

Answer 3

it is not necessary if you have only one instruction after the If or Else. if there is more than one instruction, you need braces

Answer 4

Thank you All
