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.

//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

should be one { after that first for in the definition of your function

Thanks unregister(s)

But..there is a run time error,though it compiles perfectly,when I run the prog. given by u.

Please please help, I am completely lost:(

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....

Thankx all of u for replying.
Yup Fordy ,it worked now.
Please tell me ,why u thought of reinitialising the count??
I mean ,I am just new to this concept of programming.How did u think of that logic.And how to develop it....???
I mean I feeling so dumb ..I thought why I cant think of such things..Please let me know ur secret:)
