以上是我写的代码，不知道为什么老出现
error C2143: syntax error : missing ')' before ';'和error C2059: syntax error : ')'。
出错的地方是S.base = (SElemType *)realloc(S.base,(S.stacksize+STACKINCREMENT) * sizeof(SElemType));
和S.base = (SElemType *)malloc(STACK_INIT_SIZE * sizeof(SElemType));
小弟初学望高手指点，在这先谢谢了

这是不是那本书上的原码啊?

是原来的代码，我现在已经知道了，只是编译器的问题。vc6.0不好识别多个下划线的变量，用数字代替就没问题了
