輸入姓名和分數並列出最高和最低
輸入學生的名字和分數，然後找出最高分和最低分的姓名及其分數。教科書上的寫法：
#include <stdio.h>
int main(void){
char name,*highname,*lowname;
int rate,i,high,low;
printf("Enter name and points:\n");
for(i=0;i<5;i++)
scanf("%s %d",name,&rate);
low=30000;high=0;
for(i=0;i<5;i++)
{
if(rate>high)
{high=rate;
highname=name;}
if(rate<low)
{low=rate;
lowname=name;}
}
printf("High point is %d by %s, and low point is %d by %s.",high,highname,low,lowname);
return 0;
}
我後來自己的寫法，還可以依序排出所有的高低：
#include <stdio.h>
int main(void){
char name,test;
int rate,temp;
int i,j;
for(i=0;i<6;i++)
{
printf("Enter name and rate:\n");
scanf("%s %d",name,&rate);
}
for(i=0;i<6;i++)
for (j=i+1;j<6;j++) //用 j=i+1 才好，如果直接用 i+1 則可能會往後多出一個元素。
if(rate>rate) {
temp=rate;
rate=rate;
rate=temp;
strcpy(test,name);
strcpy(name,name);
strcpy(name,test);
}
printf("The high rate is %d by %s, and low rate is %d by %s.\n",rate,name,rate,name);
return 0;
}
