[C++知识库]C语言24点小游戏

不知道大家有没有玩过计算器语音播报的24点游戏，学习C语言之后，一直想写一下，正好暑假有时间造作，写的还有不足之处，希望大家多指正

就不过多解说了，看代码

#include <stdio.h>
#include <stdlib.h>
#include <time.h>

void SetNum(void);
void play(void);
void jump(void);
int twonum(int num1, char op, int num2);
int expression_1(int num1, int num2, int num3, int num4, char sy1, char sy2, char sy3);
int expression_2(int num1, int num2, int num3, int num4, char sy1, char sy2, char sy3);

大家感兴趣的话可以贴到翻译器玩一玩，其中在运算的地方借鉴了一个博友的文章，在运算的地方还是有一些小bug,在详情里面介绍了在这里附上链接（大家写的24点小游戏规则都不一样）另外一个博主的
