求大佬解释，我这段代码哪错了

[Fire_Sky_Ho]

#include<iostream>
using namespace std;

struct student 
{
	int num;

	char name[10];

	int score1;

	int score2;

	int score3;

	float aver;
};

void main()
{
	void input(struct student stu[]);

	void scoresort(struct student stu[]);
	
	void output(struct student stu[]);

	struct student stu[3],*p=stu;

	input(p);

	scoresort(p);

	output(p);
	
}

void input(struct student stu[])
{
	int i;

	printf("NUM\tNAME\tSCORE1\tSCORE2\tSCORE3\n");

	for(i=0;i<3;i++)

	{

		scanf("%d%s%d%d%d",&stu[i].num,stu[i].name,&stu[i].score1,&stu[i].score2,&stu[i].score3);

		stu[i].aver=(stu[i].score1+stu[i].score2+stu[i].score3)/3;

	}

	printf("\n");
	
	cout<<"Before Sort:"<<endl;

	printf("NUM\tNAME\tSCORE1\tSCORE2\tSCORE3\tAVERAGE\n");

	printf("\n");

	
}

{
	int i=0,j,k;   
	struct student p;
	
	for(;i<2;i++)
	{	k=i;
		
		for(j=i+1;j<3;j++)
			
			if(stu[j].aver>stu[k].aver) k=j;
				
				if(k!=i)
				
				{
					p=stu[i];stu[j]=stu[k];stu[k]=p;
				}

			
			
}

void output(struct student stu[])

{
	int i;        
	
	cout<<"After Sort:"<<endl;
	
	printf("NUM\tNAME\tSCORE1\tSCORE2\tSCORE3\tAVERAGE\n");

错哪了，要咋改啊!

scoresort里面少了些 } 右大括号

[paschen]

大括号不对称，这样改：

#include<iostream>
using namespace std;

struct student 
{
	int num;

	char name[10];

	int score1;

	int score2;

	int score3;

	float aver;
};

void main()
{
	void input(struct student stu[]);

	void scoresort(struct student stu[]);

	void output(struct student stu[]);

	struct student stu[3],*p=stu;

	input(p);

	scoresort(p);

	output(p);

}

void input(struct student stu[])
{
	int i;

	printf("NUM\tNAME\tSCORE1\tSCORE2\tSCORE3\n");

	for(i=0;i<3;i++)

	{

		scanf("%d%s%d%d%d",&stu[i].num,stu[i].name,&stu[i].score1,&stu[i].score2,&stu[i].score3);

		stu[i].aver=(stu[i].score1+stu[i].score2+stu[i].score3)/3;

	}

	printf("\n");

	cout<<"Before Sort:"<<endl;

	printf("NUM\tNAME\tSCORE1\tSCORE2\tSCORE3\tAVERAGE\n");

	for(i=0;i<3;i++)

		printf("%d\t%s\t%d\t%d\t%d\t%f\n",stu[i].num,stu[i].name,stu[i].score1,stu[i].score2,stu[i].score3,stu[i].aver); 

	printf("\n");


}

void scoresort(struct student stu[])
{
	int i=0,j,k;   
	struct student p;

	for(;i<2;i++)
	{    k=i;

	for(j=i+1;j<3;j++)

		if(stu[j].aver>stu[k].aver) k=j;

	if(k!=i)

	{
		p=stu[i];stu[j]=stu[k];stu[k]=p;
	}



	}
}

void output(struct student stu[])
{
	int i;        

	cout<<"After Sort:"<<endl;

	printf("NUM\tNAME\tSCORE1\tSCORE2\tSCORE3\tAVERAGE\n");

	for(i=0;i<3;i++)

		printf("%d\t%s\t%d\t%d\t%d\t%f\n",stu[i].num,stu[i].name,stu[i].score1,stu[i].score2,stu[i].score3,stu[i].aver); 

	printf("\n");
}

偶遇到类似问题都是用 “每次用/*...*/注释掉不同部分再重新编译，直到定位到具体语法出错的位置。” 的方法解决的。

scoresort里的for循环的大括号不对称

函数声明，建议不要放在main函数里，放在函数之外，main函数之上最好；
