C++ Lib实例

Lib文件的调用:

1.生成的Lib文件和对应的头文件[MyStaticLib.h  StaticLib.lib]复制到工程目录

2.将2个文件[MyStaticLib.h  StaticLib.lib]导入工程

 1 #include <iostream>
 2 #include "MyStaticLib.h"
 3 using namespace std;
 4 #pragma comment(lib,"StaticLib")
 5 int main()
 6 {
 7     int m = 700, n = 360;
 8     cout << "MaxCommDiv: " << GetMaxCommDiv(m, n) << endl;
 9     cout << "MinCommMul: " << GetMinCommMul(m, n) << endl;
10 }
