Thread: Problem

I am writing a program that among other things prints out an array of characters. In order for it to work, I need to print a new line to the console. Without this, it freezes. Can anyone suggest why this is happening?

Code:

for(i = 5; i >= 0; i--){
        printf("%c", test[i]);
    }
    
printf("\n");

If I comment out the "printf("\n");" statement, it freezes before it gets to this part of the code. My program also makes use of threads. Any help would be much appreciated.

Thank you very much, sorted.
