    beginner help c++

    hey mates I need some help and have some question.

    Code:
    #include <iostream>
    #include <string>
    #include <cstdlib>
    #include <ctime> 
    
    using namespace std;
    
    
    int main()
    {
    int in = 0;
    cout << "type a value" << endl;
    cin >> in;
    for(int j = 0; j < in; j++) 
    
    for(int i = 0; i <= j; i++)
    
    cout << "*";
    
    cout << endl;
    
    
    
    
    return 0;
    }
    Is there a way to loop this program til I type the integer value 0, it will shut down?
    I would appreciated if anyone would add this to my code.

    A question

    for(int j = 0; j < in; j++)

    for(int i = 0; i <= j; i++)

    can anyone tell my in simplified laughed what they do? especially the second one, the first one kind of shows shows the "*" given what value you type, not sure.


    Cheers

    for your first question learn about while loops to do it.

    the second one what don't you understand? note IMO i think you should always use curly braces when writing for loops, even when there is only one statement following.
