stack.h

用c语言编写的关于pascal语言语法分析,词法分析,语义分析(输出有点问题)

#define maxsize 8
typedef struct{
	char data[maxsize];
	int top;
}node; 
void init(node *p)
{
	p->top=0;
}
void push(node *st,char x)
{
	if(st->top==maxsize)
	{
		printf("\n the sequence stack is full!");
	}
	st->data[st->top]=x;
	st->top++;
}
char pop(node *st)
{
	st->top--;
	return st->data[st->top];
}
void d_c(int k,char *p)
{
	node *s;
	char c;
	init(s);
	c=(char)(k%10+'0');
	push(s,c);
	while(k/10)
	{
		k=k/10;
		c=(char)(k%10+'0');
	    push(s,c);
	}
	while(s->top)
		*(p++)=pop(s);
}
