用结构体找最低成绩的问题。
代码如下:#include<stdio.h>
#include<string.h>
#include<conio.h>
#include<stdlib.h>
#define N 10
typedef struct ss
{ char num[10];
int s;
} STU;
fun(STU a[], STU *s)
{
int i;
s = a;
for (i = 0; i < N; i++)
{
if (s -> s > a[i].s )
s = &a[i];
}
return s; // 警告返回有问题 但这是上机程序设计题 只能改子函数大括号里的内容,怎么办?
}
void main()
{
FILE *wf;
STU a[N]={{ "A01",81},{ "A02",89},{ "A03",66},{ "A04",87},{ "A05",77},
{ "A06",90},{ "A07",79},{ "A08",61},{ "A09",80},{ "A10",71}},m;
int i;
system("CLS");
printf("*****The original data*****\n");
for(i=0;i<N;i++)
printf("No=%s Mark=%d\n", a[i].num,a[i].s);
fun(a,&m);
printf("*****THE RESULT*****\n");
printf("The lowest :%s, %d\n",m.num,m.s);
/******************************/
wf=fopen("out.dat","w");
fprintf(wf,"%s, %d",m.num,m.s);
fclose(wf);
/*****************************/
