创建静态库项目
1.创建静态项目MathFucsLib:
选择 win32控制台应用程序->输入MathFuncsLib项目名称->下一步->选择 静态库;取消 默认的预编译头->完毕
2.向静态库添加类MyMathFuncs:
#pragma once
//MathFuncsLib.h
namespace MathFuncs
{
class MyMathFuncs
{
public:
static double Add(double a,double b);
static double Substract(double a,double b);
static double Multiply(double a,double b);
static double Divide(double a,double b);
};
}
//MathFuncsLib.cpp
#include "MathFuncsLib.h"
#include <stdexcept>
using namespace std;
namespace MathFuncs
{
double MyMathFuncs::Add(double a,double b)
{
return a+b;
}
double MyMathFuncs::Substract(double a,double b)
{
return a-b;
}
double MyMathFuncs::Multiply(double a,double b)
{
return a*b;
}
double MyMathFuncs::Divide(double a,double b)
{
if (b==0)
{
throw new invalid_argument("b cannot be zero!");
}
return a/b;
}
}
3.确认生成的是lib文件:项目,属性->配置属性,常规->配置类型:改为静态库(.lib);编译生成MathFuncsLib.lib
