运行没有错误但就是出现local variable 's' used without having been initialized这个的错误
#include#include#define MAXNUM 20struct stacktype{int stack[MAXNUM];int top;};void InitStack(struct stacktype *s){s->top=-1;}int StackEmpty(struct stacktype *s){return(s->top==0);}int push(struct stacktype *s,int x){ if(s->top >= MAXNUM-1)return fals
int e;
struct stacktype *s=NULL;
InitStack(s);
编译器说你的s没有初始化 你就把它赋值为NULL就可以了 像我这样
