C学生成绩统计

输入10个学生的成绩，输出平均分，最高分，最低分
输入一个分数，输出多少学生比这个分数高

   #include <stdio.h>
    
    void main()
    {
    	int grade[10],grade0[10];
    	int i, maxGrade, minGrade,tmp,x,m=0;
    	double avg,sum=0;
    	printf("输入10个学生的成绩:\n");
    	for (i = 0; i < 10; i++)
    	{
    		scanf("%d", &grade[i]);
    		grade0[i] = grade[i];
    	}
    	for (int i= 0; i < 9; i++)
    		for (int j = 0; j < 9; j++)
    			if (grade[j] > grade[j + 1]) {
    				tmp = grade[j];
    				grade[j] = grade[j + 1];
    				grade[j + 1] = tmp;
    			}
    	
    	for (i = 0; i < 10; i++) {
    		if (grade0[i] == grade[0]) minGrade = i + 1;
    		if (grade0[i] == grade[9]) maxGrade = i + 1;
    	}
    	for (i = 0; i < 10; i++)
    		sum += grade[i];
    	avg = sum / 10;
    	printf("average=%.1lf ", avg);
    	printf("max=%d ", maxGrade);
    	printf("min=%d\n", minGrade);
    	printf("请输入一个分数:");
    	scanf("%d", &x);
    	for (i = 0; i < 10; i++) 
    		if (grade[i] >= x) m++;
    	printf("%d students", m);
    }
