思路很清晰的c++课件。例子很简明

例2.10 函数重载

#include <iostream.h>

int square(int x){  return x*x;}
float square(float x){return x*x;}
double square(double x){return x*x;}

int main()
{	int i=12;
	float f=3.4f;
	double d=5.67;
	cout<<i<<'*'<<i<<'='<<square(i)<<endl;
	cout<<f<<'*'<<f<<'='<<square(f)<<endl;
	cout<<d<<'*'<<d<<'='<<square(d)<<endl;
	return 0;
}
