Why does my program keep freezing when I want to print the scanned person?

Yes, I meant Visual C. I tried to run my program without system("pause"); and it still freezes.
You are declaring
TPerson *personlist[100] = {0};
each time through your loop. . .
Oh my gosh, thanks PCrumley48! I didn't notice it:) Problem is solved, thanks for the answers.
