Software Technology Experimental Course - a stack

Software Technology Experiment Class Code

 

I. stack section

#include <stdio.h>
#include <stdlib.h>
#define maxsize 1024
typedef int datatype;
typedef struct 
{
	datatype elements[maxsize];
	int Top;
 }Stack;
 void setNull(Stack *s)
 {
 	s->Top = -1;
 }
 int isfull(Stack *s)
 {
 	if(s->Top >= maxsize - 1)
 	return 1;
 	else
 	return 0;
 }
 int isempty(Stack *s)
 {
 	if(s->Top == -1)
 	return 1;
 	return 0;
 }
 void push(Stack *s, datatype E)
 {
 	if(s->Top >= maxsize -1 )
 	{
 		printf("Stack Overflow");
	 }
	 else
	 {
	 	s->Top++;
	 	s->elements[s->Top] = E;
	 }
 }
datatype *pop(Stack *s)
{
	datatype *temp;
	if(isempty(s))
	{
		printf("Stack Underflow");
		return (NULL);
	}
	else
	{
		s->Top--;
		temp = (datatype *)malloc(sizeof(datatype));
		*temp = s->elements[s->Top+1];
		return temp;
	}
}
void conversion(int n)
{
	Stack s;
	setNull(&s);
	int r,m;
	r = n;
	while(r)
	{
		m = r%2;
		if(isfull(&s))
		printf("Overflow\n");
		else
		push(&s,m);
		r/=2;
	}
	printf("转换后的二进制是\n");
	while(!isempty(&s))
	printf("%d",*pop(&s));
	printf("\n"); 
}
int main()
{
	int num;
	printf("请输入需要转换的二进制数:\n");
	scanf("%d",&num);
	conversion(num);
}

The teacher will ask the octal and hexadecimal to write extensions

This write it on their own!
