编译一个C程序时，我得到这个错误：hello：没有这样的文件或目录 [英] When compiling a C program, i get this error: hello: no such file or directory

问题描述

我之前编写过其他程序，但由于某种原因，我再也无法工作了。我有一个mac这是我的代码。它的目的是获取三个数字并找到平均值。

I have compiled other programs before but, for some reason, I can't work anymore. I have a mac Here's my code. Its purpose is to take three numbers and find the average.

#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。我在桌面上放置了average.c和average.h。我打开终端并键入

These are the steps I have taken. I put average.c and average.h on the desktop. I open terminal and type

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

然后它说：

Then it says:

average: No such file or directory.

我是一名编程初学者，不知道该怎么做。

I am a beginner at coding and don't know what to do.

推荐答案

我假设你希望输出文件是 average ？然后使用这个：

I assume you want the output file to be average? Then use this:

gcc average.c -o average
