I'm in need of a c++ code..a simple code without algorithms, stdexcept.. numbers starts from 0 to 9

Here is a sample run, where the program picked 9736: Enter a 4 digit number(unique digits): 0987 bulls 0 and cows 2 Enter a 4 digit number(unique digits): 9078 bulls 1 and cows 1 Enter a 4 digit number(unique digits): 9780 bulls 2 and cows 0 Enter a 4 digit number(unique digits): 9580 bulls 1 and cows 0 Enter a 4 digit number(unique digits): 9740 bulls 2 and cows 0 Enter a 4 digit number(unique digits): 9721 bulls 2 and cows 0 Enter a 4 digit number(unique digits): 9768 bulls 2 and cows 1 Enter a 4 digit number(unique digits): 9785 bulls = 2 and cows = 0
