cout<<"Processing fib("<< n <<")...";

这句话是什么意思？
特别是 fib("<< n <<")引号“”之内 能这样搞吗？

[sunfen0307]

输出应该是：Processing fib( n )... //备注 n为具体值。

你自己把引号匹配错了吧，cout 那句应该是这么匹配的。

cout<<      "Processing fib("           << n <<          ")...";

[无芒]

这个意思
cout << "Processing fib(" << n << ")..." ;

C/C++ code


cout<< "Processing fib(" << n << ")...";

这是可以执行的源代码：
// Fibonacci series using recursion
#include <iostream>
int fib(int n);
using namespace std;
int main()
{

int n,answer;
cout<<"Enter number to find :";
cin>>n;

cout<<"\n\n";

answer = fib(n);

cout<<answer<<" is the "<<n;
cout<<"th Fibonacci number\n";
return 0;
}

int fib(int n)
{
cout<<"Processing fib("<< n <<")...";

if(n<3)
{
cout<<"Return 1!\n";
return (1);
}
else
{
cout<<"Call fib(" << n-2 <<")";
cout<<" and fib(" <<n-1 <<").\n";
return( fib(n-2) + fib(n-1) );

}
}
// Fibonacci series using recursion
#include <iostream>
int fib(int n);
using namespace std;
int main()
{

int n,answer;
cout<<"Enter number to find :";
cin>>n;

cout<<"\n\n";

answer = fib(n);

cout<<answer<<" is the "<<n;

}

return (1);
}
else
{
cout<<"Call fib(" << n-2 <<")";
cout<<" and fib(" <<n-1 <<").\n";
return( fib(n-2) + fib(n-1) );

}
}

去敲一遍，然后解释我的那个问题。

[lirunfa]

cout<<"Processing fib("<< n <<")...";

看好引号是怎么配对的，前两个一对，后两个一对
