Have problem in C++

Question

#include <iostream>
using namespace std;

int main() {
//Your code
int x;
cin>>x;
while(0>x<50){
if(x<50)
cout<<50-x;
break;
else if(x>50)
x-50;
}
}
return 0;
}

Check my code. I can't find problem. Copy it and past in your IDE.

while (0 > x < 50) //wrong syntax

Answer 2

What does your compiler say ?

wasn't the warnings and error messages clear enough to convey the problems in your program ?
if so, then which perticular message didn't made sense to you ?
