[求助]哪位请指点一下我错在哪里,谢谢!

我是初学者,安装了dev c++的开发工具,但是使用起来偶尔会出问题。即按照书本的案例编写的程序,仔细检查了几遍,和书上的一样,但是运行时仍会提示错误,该如何是好?

#include <iostream>

int Doubler(int AmountToDouble);

int main()
{
using std::cout;

int result = 0;
int input;

cout << "Enter a number between 0 and 10,000 to double:";
std::cin >> input;

cout << "\nBefore doubler is called...";
cout << "\ninput:" << input << " doubled:" << result << "\n";

result = Doubler(input);

cout << "\Back from Doubler...\n";
cout << "\ninput:" << input << " doubled:" << result << "\n";
char response;
std::cin>>response;
return 0;
}

int Double(int original)
{
if (original <= 10000)
return original * 2;
else
return -1;
std::cout << "You can't get here!\n";
}

result = Doubler(input);
int Double(int original)

函数名不一样

函数应该有前向声明

应该有 <iostream>

你哪炒错了吧?、
#include <iostream>

int Doubler(int AmountToDouble);


int main()
{
using std::cout;

int result = 0;
int input;

cout << "Enter a number between 0 and 10,000 to double:";
std::cin >> input;

cout << "\nBefore doubler is called...";
cout << "\ninput:" << input << " doubled:" << result << "\n";

result = Doubler(input);

cout << "\nBack from Doubler...\n";
cout << "\ninput:" << input << " doubled:" << result << "\n";
char response;
std::cin>>response;
return 0;
}

int Doubler(int original)
{
if (original <= 10000)
return original * 2;
else
return -1;
std::cout << "You can't get here!\n";
}
