用冒泡写感觉简单点.
再问： 加上输出不及格的人数
再答： #include #include #define STU 10 //宏定义学生人数，改起来方便 #define SCORE 60 //学生及格分数线 int main() { int score[STU]; int i; int j; int t; int num = 0; printf("please input ten number:"); for(i = 0; i < STU; i++) { scanf("%d",&score[i]); } for(i = 0; i < STU; i++) { for(j = 0; j < STU-1; j++) { if(score[j]>score[j+1]) { t = score[j]; score[j] =score[j+1]; score[j+1] = t; } } } printf("The high score is :%d\n",score[STU-1]); printf("The low score is :%d\n",score[0]); for(i = 0; i < STU; i++) { if(score[i] < SCORE) { num++; } else break; } printf("The count of students to fail is:%d\n",num); printf("The rate of students to fail is :%0.2f %%\n",100*(float)num/STU); return 0; }
