杭电 -- 1062 解法一

#include<stdio.h>
#include<malloc.h>
#define MaxSize 100

typedef struct{
    char arr[MaxSize];
    int top;
}Stack;

void InitStack(Stack *&s){
    s = (Stack *)malloc(sizeof(Stack));
    s->top = -1;
}

void DestroyStack(Stack *&s){
    free(s);
}

void push(Stack *&s,char c){
    if( (s->top+1)==MaxSize-1){
        printf("stack is full!\n");
    }else{
        s->arr[++s->top] = c;
    }
}

void pop(Stack *&s){
    if(s->top==-1){
        printf("stack is null!\n");
        return;
    }
    while(s->top>-1){
        printf("%c",s->arr[s->top--]);
    }
}

int main(){
    int loop = 0;
    scanf("%d",&loop);
    char c;
    //init
    Stack *s;
    InitStack(s);
    //null getter
    getchar();
    while(loop--){
        while( (c=getchar())!=‘\n‘ ){
            if(c!=‘ ‘){//push
                push(s,c);
            }else{//pop
                pop(s);
                printf(" ");
            }
        }
        pop(s);
        printf("\n");
        //reset top
        s->top = -1;
    }
    DestroyStack(s);
    return 0;
}

采用栈的先进后出的特点完成逆序输出，但是杭电判定编译错误，指出缺少 ")" 等未知错误！暂时不知道如何解决！
