为什么我的程序不对(stack.cpp)

[XBug]

//stack.h
// A traditional c implementation of type stack

const int max_len=1000;
enum boolean {false,true};
enum {EMPTY=-1,FULL=max_len-1};

struct stack
{
char s[max_len];
int top;
};

void reset(stack *stk)
{
stk->top=EMPTY;
}
void push(char c,stack* stk)
{
stk->top++;
stk->s[stk->top]=c;
}

char pop(stack* stk)
{
return(stk->s[stk->top--]);
}

char top(stack* stk)
{
return(stk->s[stk->top]);
}

boolean empty(const stack* stk)
{
return (boolean)(stk->top==EMPTY);
}

boolean full(const stack* stk)
{
return (boolean)(stk->top==FULL);
}

//stack.cpp
//Test of sack implementation by reversing a string

#include <iostream>
#include "stack.h" //stack implementation imported

main()
{
stack s;
char str[40]={"My name is Betty Dolsberry!"};
int i=0;

std::cout<<str<<'\n'; //print the string
reset(&s);
while(str[i]) //push onto stack
if(!full(&s))
push(str[i++],&s);
while(!empty(&s))
std::cout<<pop(&s);
std::cout<<'\n';
}

TO: OpenGLPrimer(大水雷)
的确是这两个地方的问题 但是为什么会出现这样的问题呢??

[wangfengsdu]

完全按照标准C++的标准写。
你的main()函数前面都没有返回值，
加个int吧。。

说说有什么问题先...

单步跟踪，看到哪一步出的错，问题就容易排除了。
