源代码如下：

#include<stdio.h>#include<stdlib.h>#include<time.h>//生成随机函数起点时用到time.hint main(){ int number1 = 0, choice = 0, number2 = 0; printf("$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$\n");//界面设置 printf("$$$$$ 欢 迎 来 到 $$$$$\n"); printf("$$$$$ 猜 数 字 游 戏 $$$$$\n"); printf("$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$\n"); printf(" 1.进入游戏\n"); printf(" 2.退出游戏\n"); scanf("%d", &choice); srand((unsigned int)time(NULL));//设置随机数起点 while (choice == 1) { printf("请输入所猜的数:\n"); scanf("%d", &number2); number1 = rand() % 100; while (1) { if (number2 == number1) { printf("666 恭喜你答对了！"); printf("\n1.再玩一次\n2.退出游戏\n"); scanf("%d", &number2); if (number2 == 1) break; if (number2 == 2) return 0; } if (number2 < number1) { printf("\n猜小了!\n"); scanf("%d", &number2); } if (number2 > number1) { printf("\n猜大了!\n"); scanf("%d", &number2); } } } while(choice == 2) { return 0; } system("pause"); return 0;}

运行结果：
