编程序遇到问题，不会修改，求指导。3q

[三日之别]

运行不对，求指导，先谢谢了！

#include <stdio.h>
#include <malloc.h>

struct student()
{
int age;
float score;
char name[100];
}

void f(int i,int len)
{

for(i=0; i<len; ++i)
{
printf("请输入第%d个学生的信息: ", i+1);
printf("age = ");
scanf("%d", &parr[i].age);

printf("name = ");
scanf("%s", parr[i].name);

printf("score = ");
scanf("%f", &parr[i].score);

}
return;
}

void g(int * parr,int len)
{
for (i=0; i<len-1; ++i)
{
for (j=0; j<len-1-i; ++j)
{
if (parr[j].score > parr[j+1].score)
{
t = parr[j];
parr[j] = parr[j+1];
parr[j+1] = t;
}
}
}
return;
}

void k(int i,int len)
{

for(i=0; i<len; ++i)
{
printf("第%d个学生的信息是:\n", i+1);
printf("age = ", &parr[i].age);
printf("name = ", parr[i].name);
printf("score = ", &parr[i].score);

pintf("\n");
}
return;
}



int main (void)
{
int len;
struct student * parr;
printf("请输入学生的个数：\n");
printf(" len = ");
scanf("%d", &len);
parr = (struct student *)malloc(len * sizeof(struct student));
f(i,len);
g(parr,len);
k(i,len);

return 0;

}

你的代码问题实在是多，封装的函数，用到了很多没有定义的变量，这些变量你可以设置为全局的，不然你这个是编译不过去的，自己改吧

[大奶兔白糖]

楼主首先要学会看编译器提示的编译错误，先把代码编译了再说。运行不对？能运行吗？

[iaccepted]

有些变量i和t等都没定义，另外一个循环用的变量还需要作为参数传入，用意何在？ 代码的风格也有很大的问题啊，我觉着得多写多练了。 这个代码不是运行错误的问题，应该直接没法运行，错误太多。

强烈要求 楼主提高编程思想 ，此程序虽然看着小，但是 经过楼主的加工 是在让调试人员 痛不欲生 。 本着最小的改动 给你改了改！ #include <stdio.h> #include <malloc.h> typedef struct student { int age; float score; char name[100]; }st; void f(st *parr,int i,int len) { for(i=0; i<len; ++i) { printf("请输入第%d个学生的信息: ", i+1); printf("age = "); scanf("%d", &parr[i].age); printf("name = "); scanf("%s", parr[i].name); printf("score = "); scanf("%f", &parr[i].score); } return; } void g(st * parr,int len) { int i,j,k; st t; for (i=0; i<len-1; ++i) { for (j=0; j<len-1-i; ++j) { if (parr[j].score > parr[j+1].score) { t = parr[j]; parr[j] = parr[j+1]; parr[j+1] = t; } } } return; } void k(st *parr,int len) { int i =0; for(i=0; i<len; ++i) { printf("第%d个学生的信息是:\n", i+1); printf("age = %d", parr[i].age); printf("name = %s", parr[i].name); printf("score = %lf", parr[i].score); printf("\n"); } return; } int main (void) { int len; int i=0 ; printf("请输入学生的个数：\n"); printf(" len = "); scanf("%d", &len); struct student *parr; parr = (struct student *)malloc(len * sizeof(struct student)); f(parr,i,len); g(parr,len); k(parr,len); return 0; }

[木木口口]

void k(int i,int len) { for(i=0; i<len; ++i) { printf("第%d个学生的信息是:\n", i+1); printf("age = ", &parr[i].age); printf("name = ", parr[i].name); printf("score = ", &parr[i].score); pintf("\n"); } return; } 看到楼主这里的printf格式我就真的不想再看下去了，建议还是先看看C语言基础

[「已注销」]

楼主这个代码格式，，，，，，，，，
