嘿伙计我的C项目中有一个带有功能指针的编译错误。
感谢您的帮助:)
文件夹结构:
主文件夹: enter image description here
自定义文件夹: enter image description here
Heder Folder:
路径: C-Lib/Headers
档案:ShowPointer.h
代码(Main.c):
#include <stdio.h>
#include "./Headers/ShowPointer.h"
int main(){
printf("Hej this is written in VIM some C code.\n");
getchar();
}
代码(ShowPointer.c):
#include <stdio.h>
#include "../Headers/ShowPointer.h"
void ExPointer(int *pPointer, int *pPointerMax){
for (int i = *pPointer; i<*pPointerMax; i++){
printf("%d. %d %p\n", i, *pPointerMax-i, pPointerMax);
}
getchar();
}
代码(ShowPointer.h):
#ifndef SHOWPOINTER_FILE
#define SHOWPOINTER_FILE
typedef void ExPointer (*)(int , int);
#endif
编译: 我用这段代码编译这个项目:
gcc -o main main.c Lib/ShowAddress.c
错误: 出于编译错误文本(代码):
In file included from main.c:2:0:
./Headers/ShowPointer.h:4:25: error: expected declaration specifiers or ‘...’ before ‘*’ token
typedef void ExPointer (*)(int , int);
^
In file included from Lib/ShowAddress.c:2:0:
Lib/../Headers/ShowPointer.h:4:25: error: expected declaration specifiers or ‘...’ before ‘*’ token
typedef void ExPointer (*)(int , int);
对不起,我的英语不好。

你想要
public override string ToString()
{
return $"[{code},{param},{len}]";
}
