    Return what??

    Help please for giving me any tips .....

    My problem is I dont know here what to return in the function defination.????
    This is the question.
    Write a funcn that displays a solid square of asterisks whose side is specified in integer parameter side.For eg.
    if side is 4 the funcn displays
    ****
    ****
    ****
    ****

    My code till now:

    int solid sq(int)
    int main()
    {
    int num;
    cout<<"enter how many sides"<<endl;
    cin>>num;
    cout<<solidsq(num)------------ ???//NOT SURE//
    return 0;
    }
    int soildsq(int x)
    {
    int counter=0;
    int count =0;
    for(counter=0;counter<=x;counter++)
    {
    for(count=0;count<=x;count++)
    {
    cout<<"*";
    }
    cout<<endl;
    }
    return ???????---------NOT AT ALL SURE???
    }

    the general rule is return a zero if the program ran successfully and a non-zero if it failed or errored. Follow this unless you have a specific reason to return another value.

    void soildsq(int x)//not too sure about making it void
    //but it doesn't look like you are returning anything
    {
    int counter=1;// having a 0 would make it have 5 *
    int count =1;// same as above
    for( ;counter<=x;counter++)//the first part has already
    //been intialized
    for( ;count<=x;count++)
    {
    cout<<"*";
    }
    cout<<endl;
    }
    }
    not sure if it will work because i don't have a compiler

    Code:
    #include <iostream>
    using namespace std;
    
    void solidsq(int x);
    
    int main() 
    { 
    int num; 
    cout<<"enter how many sides"<<endl; 
    cin>>num; 
    solidsq(num);
    
    return 0; 
    } 
    void solidsq(int x)
    { 
    int counter=1;
    int count =1;
    for( ;counter<=x;counter++){
    for( ;count<=x;count++){cout<<"*";}
    count = 1; // Put counter back to original value
    cout<<endl; }
    return;
    }
    That should compile.....well it does on mine....
