I enter numbers in the console, press Enter, and it closes immediately

#include <iostream> #include <string> #include <conio.h> using namespace std; int main() { int number; cout << "Enter a number: "; cin >> number; cout << endl; if (number > 0) { cout << "1"; } else if (number == 0) { cout << "0"; } else if (number < 0) { cout << "-1"; } getch(); return 0; }

Namit Jain (if else) is very much supported feature in C++. 👇 https://code.sololearn.com/cK46a8054SDU/?ref=app And Sin Cara M as far as problem is conserned in your code then it is nothing just that you are using outdated C++ headers(conio.h) which is no longer a standard header. Here is the fix of your code👇 https://code.sololearn.com/cz9PM5k9Nw0L/?ref=app

Namit Jain Anything greater than 0 should be displayed "1", anything less than 0 is displayed "-1", if 0 then "0"

I don't think 'else if' is anything in C++ C++ has only if and else C has if/else if/else So according to me you will have to make nested conditions to make it work correctly...
