This article mainly explains "C language how to achieve random card selection program", interested friends may wish to take a look. The method introduced in this paper is simple, fast and practical. Next let the editor to take you to learn "C language how to achieve random card program" it!

Programming requirements

This procedure is responsible for issuing a deck of standard cards, each of which has a variety of colors (clubs, diamonds, spades, hearts) and a grade (2, 3, 4, 4, 5, 6). KJA). The program requires the user to indicate how many cards the phone has.

Programming process

1. Use the library function and the time function, use the time function to return the current time, represent it with a number, and the srand function initializes the C language random number generator. By passing the return value of the time function to srand, you can prevent the program from dealing the same cards every time it runs. The rand function produces random numbers by% scaling.

2. Use a two-digit array to record data. Four rows represent each color, and thirteen columns represent each grade.

3. At the beginning of the program, the array elements are false, each randomly selected a card, check the in_hand corresponding element true or false, if true, then extract other cards, if false, record to the array elements, remind us that this card has been recorded.
