This article mainly describes how to split classes into separate .c and .h files in C++
1.C file
#include"circle.h"
Circle::Circle()
{
radius = 1.0;
}
Circle::Circle(double radius_)
{
radius = radius_;
}
double Circle::getArea()
{
return (3.14 * radius * radius);
}
2. Header file (.h)
#pragma once
class Circle
{
private:
double radius;
public:
Circle();
Circle(double radius_);
double getArea();
};
3.main function file
#include<iostream>
#include"circle.h"
int main()
{
Circle c1;
Circle c2{
2.0 };
std::cout << c1.getArea() << std::endl;
std::cout << c2.getArea() << std::endl;
}
Summarize
1. Appropriate splitting can make the code function clearer and clearer. If you don't understand, please leave a message.
