编译C程序时,我收到此错误:hello:没有这样的文件或目录

Question

我以前编译过其他程序,但由于某种原因,我不能再工作了.我有一个mac这是我的代码.它的目的是取三个数字并找到平均值.

#include <stdio.h>
int main(){
int first;
int second;
int third;
float average=0.0;
    printf ("This program will find the average of 3 numbers.\n");
    delay(1000);
    printf ("Type the first number.\n");
    scanf ("%d", &first);
    printf ("Type the second number.\n");
    scanf ("%d", &second);
    printf ("Type the third number.\n");
    scanf ("%d", &third);
    average = (first+second+third)/2.0;
    printf ("The average of %d, %d, and %d is %.3f\n", first, second, third, average);
return (0);
}

这些是我采取的步骤.我把average.c和average.h放在桌面上.我打开终端并输入

cd Desktop 
gcc /Users/reneelion/Desktop/average.c average

然后它说:

average: No such file or directory.

我是编码的初学者,不知道该怎么做.

我假设你想要输出文件average？然后用这个:

gcc average.c -o average
