有如下问题：输入两个整数，输出两数之和程序如下，请指出其中的错误

#include "stdio.h"main(){ int num1,num2; printf(“please input two numbers:”); scanf(“%d%d”,&num1,&num2); sum=num1+num2printf(“tom`s prize is %d”,sum);}错误1： 错误2： 

错误一 int main(void)

错误二int sum=

改成下面这样就可以了

#include "stdio.h"
void main()
{
    int num1,num2;
    printf("please input two numbers:");
    scanf("%d%d",&num1,&num2);
    int sum=num1+num2;
    printf("tom`s prize is %d",sum);
}

int main()
{ 
	int num1,num2,sum;
	printf("please input two numbers:"); 
	scanf("%d,%d",&num1,&num2); 
	sum = num1 + num2;
	printf("tom`s prize is %d",sum);
	return 0;
}
