#include<stdio.h> #include<math.h> int main() #define N { int score[N]={67,98,75,63,82,79,81,91,66,84}; int i,j,max,min,sum; float average; for(i=0;i<10;i++) { for(j=0;j<=i;j++) { if(score[i]<score[j+1]) { int t; score[i]=t; t=score[j+1]; score[j+1]=score[i]; } } } sum+=score[i]; average=sum/10; printf("考试的总分为%d\n考试的最高分为%d\n考试的最低分为%d\n考试的平均分为%1f\n",sum,max,min,average); printf("考试降序排序为%c",score[i]); return 0; }
