error "expected initializer before 'using'" c++
提问by user3316789
im new here ,and new at proggraming in general . whem im trying to run this code:
我是新来的,一般是编程方面的新人。我正在尝试运行此代码:
#include<fstream>
#include <iostream>
#include "main.h"
using namespace std;
int main()
{
short arr_size ()
float temp;
point point_arr[99];
ifstream my_file ("points.txt");
while(!my_file.eof())
{
my_file>>temp ;
point_arr[arr_size].set_x(temp);
my_file>>temp ;
point_arr[arr_size].set_y(temp);
arr_size++;
}
arr_size--;
my_file.close();
ex_point(point_array,arr_size);
cout<<"the middle point is:("<<mid_p(point_array,arr_size).get_x()<<","<<mid_p(point_array,arr_size).get_y()<<")\n";
return 0;
}
im getting this error : "error "expected initializer before 'using'" c++" this is the first time i get this error . it may be somthing wrong with "main.h" ? this is "main.h " :
我收到此错误:“错误”在‘使用’之前的预期初始化程序”c++”这是我第一次收到此错误。“main.h”可能有问题?这是“main.h”:
#ifndef MAIN_H_INCLUDED
#define MAIN_H_INCLUDED
#include<iostream>
class point
{
float x ,y ;
public :
point(float a,float b){x=a;y=b;}
point(){};
void set_x(float a){x=a;};
void set_y(float b){x=b;};
const float get_x(){return x; };
const float get_y(){return y; };
const void show();
const float pitagoras();
};
const point mid_p(point[],float);
const void ex_point(point[],float)
#endif // MAIN_H_INCLUDED
thank you ! ivory
谢谢你 !象牙
回答by Brian
const void ex_point(point[],float)
at the end of main.h
is missing a semicolon.
末尾main.h
缺少分号。
