This article mainly explains "how to write a simple game in C language". Interested friends may wish to have a look. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn how to write a simple game in C language.

To get a random number.

Start the game of guessing numbers by writing a function to select a random number. When writing functions, good programmers try to make them flexible so that they can reuse them to solve slightly different problems. Therefore, instead of hard-coding a function to select a random number between 1 and 100, write a function to select a random number between 1 and an integer maxval:

# include # include int randnum (int maxval) {/ * pick a random number from 1 to maxval * / int randval; getrandom (& randval, sizeof (int), GRND_NONBLOCK); / * could be negative, so ensure it's positive * / if (randval

< 0) { return (-1 * randval % maxval + 1); } else { return (randval % maxval + 1); } } 该函数使用 Linux 的系统调用 getrandom 来生成一系列随机数。你可以在手册页中了解关于这个系统调用的更多信息，但请注意，getrandom 将用随机的 0 和 1 填充变量。这意味着最终值可以是正的，也可以是负的，因此你需要在之后进行测试，以确保 randnum 函数的结果是正值。 编写程序 你可以用这个函数来写你的"猜数字"程序： #include #include int randnum(int maxval) { ... } int main(void) { int number; int guess; number = randnum(100); puts("Guess a number between 1 and 100"); do { scanf("%d", &guess); if (guess < number) { puts("Too low"); } else if (guess >

Number) {puts ("Too high");}} while (guess! = number); puts ("That's right!"); return 0;}

The program first uses the randnum function to select a random number from 1 to 100. After outputting a prompt to the user, the program enters a do-while loop so that the user can guess the number.

In each iteration of the loop, the program tests the value of the user's guess. If the user's guess is less than a random number, the program will output "Too low". If the guess is greater than a random number, the program will output "Too high". The loop continues until the user's guess is the same as the random number.

When the loop exits, the program outputs "That's right!" and ends immediately:

$gcc-o guess-Wall guess.c $. / guess Guess a number between 1 and 100 50 Too high 30 Too low 40 Too low 45 Too high 42 Too low 43 Too low 44 That's right!
