得看你报这个错的那行代码，才能知道怎么改，单单是这么一个错误信息，只能知道你的那行代码缺基本表达式，但是无法判断出来如何修正。
1）case '@': ClearStack(S); break; 清空栈后，想再不初始化就再使用？top指针其实编程空指针了。2）什么情况下用变量的使用问题，typedef struct{。。。}SqStack,*S;中的*S，InitStack(S);把S当做全局指针？基础要加强。3）代码修正如下，可以正确运行。include<stdlib.h> include<stdio.h> ...

由于你的“+-*/”，是一个裸的符号，没有被单引号''给包起来，被C++编译器当成了一个实际的加减乘除的，表达式。纠错很简单，就把对应的加减乘除号，用单引号括起来：if((c==+))修改成：if(c=='+')其他类似的地方相同处理就可以。没有查看你程序的其他问题。
增加头文件 include <string.h> 错误行改为：strcpy(eq[i],"'c','d','b','=','a','|','e'");
