When printing X variable it prints "123" then the actual variable value

When you type in 4 it should output only 2 but instead it outputs 12, same goes for 6 it outputs 123 and so on and so forth

int main() {
    int salary, yearsOfService, X; //rounded off for computation of bonuse
    string companyName;
    
    std::cin >> yearsOfService;
    
    if (yearsOfService >= 1){ //X is rounded off case number for amount of years
        X = 0;
        X = 1;
        std::cout << X;
        
        if (yearsOfService>=2){
            X = 0;
            X = 2;
            std::cout << X;
        }
        if (yearsOfService>=5){
            X = 0;
            X = 3;
            std::cout << X;
        }
        if (yearsOfService>=6){
            X = 0;
            X = 4;
            std::cout << X;
        }
        if (yearsOfService>=11){
            X = 0;  
            X = 5;
            std::cout << X;
        }
            
    }
}

>Solution :

Your program is doing exactly what you told it to do. It will run down and execute those statements in sequence. It sounds like what you’re trying to do is this:

X = 0;
if (yearsOfService >= 11)
    X = 5;
else if (yearsOfService >= 6)
    X = 4;
else if (yearsOfService >= 5)
    X = 3;
else if (yearsOfService >= 2)
    X = 2;
else if (yearsOfService >= 1)
    X = 1;

if (X != 0) std::cout << X;

Another way instead of using else is to just add 1 to X any time one of these conditions is satisfied. Then you can run them in any order.
