strcat error

[Jared Russell]

I think you think that strcat does something that it doesn't. You can't just cast an int to a char * and expect it to work.

How about:

 int loop=0;
while (IsAuto())
{
     printf("%d iteration\n", ++loop);
}

That is the most direct way to accomplish what you want. Alternatively, here's how to do it with strcat() properly:

 int loop=0;
while (IsAuto())
{
     char msg[100]; // We can't just declare this as a "char *" without first allocating memory - 100 characters is more than enough
     strcat( msg, itoa(++loops) );
     strcat( msg, " iteration\n");
     printf("%s", msg);
}

The standard C itoa() function takes an integer and returns a C string of the printable characters.
