c语言纠错（以下代码错在哪？）

Question

#include"stdio.h"
main()
{int a,b;
printf("Enter a & b:");
scanf("%d%d\n",&a,&b);
printf("a, b: %d %d\n",a,b);
if(a<b)
printf("max = a = %d\n",a);
else
pirntf("min = b = %d\n",b);
printf("****end******\n");
}

Answer 1

#include<stdio.h>
/*#include"stdio.h"，这个意思是从用户目录查找，stdio.h是标准库的，应该用<>*/

void main()/*函数没有返回类型*/
{
int a,b;
printf("Enter a & b:");

/*下面的scanf里面不要回车符\n*/
scanf("%d%d",&a,&b);

printf("a, b: %d %d\n",a,b);
if(a<b)
printf("max = a = %d\n",a);
else
/*pirntf("min = b = %d\n",b);这里的printf打错了*/
printf("min = b = %d\n",b);
printf("****end******\n");
}

Answer 2

main()前面添加void空格

#include"stdio.h"
void main()
{int a,b;
printf("Enter a & b:");
scanf("%d%d\n",&a,&b);
printf("a, b: %d %d\n",a,b);
if(a<b)
printf("max = a = %d\n",a);
else
pirntf("min = b = %d\n",b);
printf("****end******\n");
}

Answer 3

#include "stdio.h"
main()
{int a,b;
printf("Enter a & b:");
scanf("%d%d",&a,&b); //\n去掉
printf("a, b: %d %d\n",a,b);
if(a<b)
printf("max = a = %d\n",a);
else
//pirntf("min = b = %d\n",b);error
printf("min = b = %d\n",b);
printf("****end******\n");
}

Answer 4

main函数貌似没返回类型喔
