Square and Hollow Square in C
Question about this C program that I've written. The objective is to print a square and a hollow square to the size input by the user. I've got the solid square down fine, but I'm having a bit of trouble with the hollow one. I understand that something must be put in between the two loops, but I'm having difficulty finding the solution. Any suggestions for this source code? Thanks a lot ... #include
int main( void )
printf( "Please Enter a Number Between 1 and 20: ")
scanf( "%d", &num );
for(row = 0; row < num; row++)
for(col = 0; col < num; col++)
