- They are called functions.
- It causes the contents of the
iostreamfile to be substituted for this directive before final compilation.- It makes definitions made in the
stdnamespace available to a program.cout << "Hello, world" << endl;orcout << "Hello, world\n";int cheeses;cheeses = 32;cin >> cheeses;cout << "We have " << cheeses << " varieties of cheese\n";- The function
froop()expects to be called with one argument, which will be typedouble, and that the function will return a typeintvalue. For instance, it could be used as follows:
int gval = froop(3.14159);
The functionrattle()has no return value and expects anintargument. For instance, it could be used as follows:
rattle(37);
The functionprune()returns anintand expects to be used without an argument. For instance, it could be used as follows:
int residue = prune();- You don‘t have to use
returnin a function when the function has the return typevoid. However, you can use it if you don‘t give a return value:
return;- The likely cause it that the function loses a statement
using namespace std;to declare a directive of output.
placeusing namespace std;above themain()function;
placeusing std::cout;in themain()function;
type as following:using std::cout << "Please enter your PIN: " << std::endl;

{
cout << "Three blind mice" << endl;
}
void f2()
{
cout << "See how they run\n"; // 也可以用f1()函数中的endl形式。
return; // void f2()表明无返回值，故可以这样写；也可以如f1()不写return语句。
