How to use try\catch\finally\throws.

[RobertTheBeast]

What exactly are these keywords. and an example of their implimentation? every time I try to use these I get errors. I understand they help in catching errors..

[clanmjc]

try/catch/throw

try
{
    //Throw an exception
    throw("A nonsense error!");
}
catch(...)
{
   std::cout << "The is an error" << std::endl;
}

Finally is not a c++ construct.

edit: @LB Whoops! Fixed

Thank you I understand it now. sorry about the "finally". I'm learning Java at the same time as c\c++.

clanmjc: You're throwing a const char* but nowhere do you catch it ;)

int x = 5;
try
{
    if(x == 0) throw(1ULL);
    else if(x % 2) throw("x must be even");
    x *= 4;
}
catch(unsigned long long e)
{
    std::cerr << e;
}
catch(const char *e)
{
    std::cerr << e;
}
