c - 刚开始使用 C 中的类

Question

# include <stdio.h>

int main(void) {

int numStudents;
int i = 0 ;
int sum;

printf("How many students are in your class? \n");
scanf("%d", &numStudents);

int grade[numStudents];


while ( i < numStudents ){
      scanf("%d", &grade[i]);
      printf("\n");
      i++;
      }

average(int grade[numStudents]);
printf("%d", &sum);     

}


int average(int x[y]){
    int sum;

    for (a=0; a<=y ;a++){
    sum = sum + x[a];
    }

    sum = sum / y;
    return sum;
}

我想问我的代码出了什么问题。

Answer 1

对于初学者来说，这个

int average(int x[y]){           /* wrong */
int average(int x[], int y){     /* probably what you want */

还有

average(int grade[numStudents]); /* totally wrong */
average(grade, numStudents);     /* might work */

平均数中有一个相差一的错误，我没有指出，因为这是家庭作业。我恳请其他发帖者不要指出这一点。
