If\s*.*[> < ]=.*\s*: what does this mean

You know that means if you use c++

you need to put something in this

#include<iostream>

using namespace std;

int what_ you_ want;

int main ()

{

cout<<"WHAT DO U WANT"; cin>>what_you_want;

if (what_you_want<1000)

and then use {, else, } return 0;

but it is good for c++
