提问by eden
I am trying to run this basic file (ex1.c) with zsh
我正在尝试使用 zsh 运行这个基本文件（ex1.c）
#include <stdio.h>
int main(int argc, char *argv[])
{
puts("hello world.");
return 0;
}
I am getting this error:
我收到此错误：
zsh: permission denied: ./ex1.c

You need to compile it first, probably by doing gcc -o ex1 ex1.c.
After compiling it, you will have an executable called ex1, which you can run by doing ./ex1.
If you receive another permission deniederror, you can make it executable by doing chmod +x ex1.
您需要先编译它，可能是通过执行gcc -o ex1 ex1.c.
编译后，您将拥有一个名为 的可执行文件ex1，您可以通过执行./ex1. 如果您收到另一个permission denied错误，您可以通过执行chmod +x ex1.

You can't just run a file with C code. You'll have to first compile it. If you have a gcccompiler available, that's going to be:
你不能只用 C 代码运行一个文件。你必须先编译它。如果你有一个gcc可用的编译器，那就是：
gcc -o ex1 ex.c
./ex1

It's a C source file, it is not supposed to be run like this, you have to compile it first.
这是一个C源文件，不应该这样运行，你必须先编译它。
This would do:
这会做：
make ex1 # Implicit rule which in turn will perform cc -o ex1 ex1.c
./ex1
