Running C on VS code: undefined reference to `WinMain'

Question

This is what it looks like on VS code terminal when I run the code.

Windows PowerShell

Try the new cross-platform PowerShell https://aka.ms/pscore6

PS D:\C C++> cd "d:\C C++\" ; if ($?) { g++ TEST.C -o TEST } ; if ($?) { .\TEST }
D:/msys64/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/11.2.0/../../../../x86_64-w64-mingw32/bin/ld.exe: D:/msys64/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/11.2.0/../../../../x86_64-w64-mingw32/lib/../lib/libmingw32.a(lib64_libmingw32_a-crt0_c.o): in function `main':
C:/M/mingw-w64-crt-git/src/mingw-w64/mingw-w64-crt/crt/crt0_c.c:18: undefined reference to `WinMain'
collect2.exe: error: ld returned 1 exit status
PS D:\C C++>

This is the simple program I tried to run.

#include<stdio.h>

int main(){
    int age;
    printf("Enter age\n");
    scanf("%d",&age);
    printf("age is %d",age);
    return 0;
}

screenshot of the program

I've never seen anyone try to run code like that. The simple gcc myCode.c -o myCode.exe doesn't work? — Raphael Sauer, Dec 30 '21 at 11:14
Save the file before running the program, it should solve the error. — Gaurav Pathak, Dec 30 '21 at 11:27
Does this answer your question? [undefined reference to \`WinMain@16'](https://stackoverflow.com/questions/5259714/undefined-reference-to-winmain16) — Gaurav Pathak, Dec 30 '21 at 12:32
Yes, I just have to save it. I forgot that the autosave is off, thank you for your help! — user17796205, Dec 31 '21 at 17:18

Save the file as said by @Gaurav Pathak and check if you've set the path to the compiler.

Try to run gcc a.c -o a.exe for once, sometimes the code runner does something unexpected.
