Question

C++写程序输出a+b+c的和

Answer 1

#include "stdafx.h"
#include <iostream>

void Max2(double a,double b)
{
int max=a>b?a:b,
cout<<"Double a "<<"and"<<" double b's Max is:"<<max<<endl;
return ;
}

void Max2(int a int b)
{
int max=a>b?a:b;
cout<<"Int a "<<"and"<<" int b's Max is:"<<max<<endl;
return ;
}
void Max3(double a,double b,double c)
{
double temp=a>b?a:b;
double max1 = temp1>c?temp:c;
cout<<"Double a "<<", double b "<<"and"<<" double c's Max is:"<<max<<endl;
return;
}

void Max3(int a,int b,int c)
{
double temp=a>b?a:b
double max= temp>c?temp:c;
cout<<"Int a "<<", int b "<<"and"<<" int c's Max is:"<<max<<endl;
}

int main(int argc, char* argv[])
{
double a,b,c;
// int a,b,c;
cin>>a;
cin>>b;
cin>>c;
Max2(a,b);
Max3(a,b,c);
return 0;
}

简单，你把第一行代码给删了

Answer 2

#include <iostream>
using namespace std;

int main()
{
int a,b,c;
cout<<"依次输入a,b,c的值，用空格或者回车分开"<<endl;
cin>>a>>b>>c;
cout<<"a+b+c="<<a+b+c<<endl;
return 0;
}

Answer 3

#include<iostream>
int main()
{
std::cout<<"Enter three nembers:"<<std::endl;
int a,b,c;
std::cin >>a>>b>>c;
std::cout << "The sum of " << a<< " and " <<b<<"and"<<c
<< " is " <<a + b + c<< std::endl;
system("PAUSE");
return 0 ;
}

Answer 4

用你的开发环境(VC6/VC2003/VC2005/VC2008/Vc2010/VC2012)创建个命令行程序工程

然后在那个工程提供的文件中编写你的代码
通过在main函数中调用你的函数完成你的需求.
