    trying if statement in the tutorial and stumble a problem

    I was doing the example in the tutorial and When I tried to run the program I got few error. Some of them I do not understand such as the file and directory is not there. cin is not identified. It also said there an error on iostream. I am using the compiler that this site directed me.(codeblock VB 2005/08) I really appreciate any feedback.

    Code:
    
    #include <iostream>
    
    using namespace std;
    
    int main ()
    {
       int age;
    
       cout<<"Please enter your Age";
       cin >>age;
       cin.ignore ();
    
       if ( age< 100)(
      cout<<"You are pretty young!\n";
      )
      else (age ==100)(
         cout<<"You are really old\n";
    )
    cin.get();
    }
    ,

    Code:
    
    C:\Users\gameffect\Documents\first1\if statements.c|1|error: iostream: No such file or directory|
    C:\Users\gameffect\Documents\first1\if statements.c|3|error: expected '=', ',', ';', 'asm' or '__attribute__' before 'namespace'|
    C:\Users\gameffect\Documents\first1\if statements.c||In function 'main':|
    C:\Users\gameffect\Documents\first1\if statements.c|9|error: 'cout' undeclared (first use in this function)|
    C:\Users\gameffect\Documents\first1\if statements.c|9|error: (Each undeclared identifier is reported only once|
    C:\Users\gameffect\Documents\first1\if statements.c|9|error: for each function it appears in.)|
    C:\Users\gameffect\Documents\first1\if statements.c|10|error: 'cin' undeclared (first use in this function)|
    C:\Users\gameffect\Documents\first1\if statements.c|14|error: expected ')' before ';' token|
    C:\Users\gameffect\Documents\first1\if statements.c|16|error: expected ';' before 'else'|

    You need to name your source files to end in .cpp, if you want to compile them as C++ programs.

    What you're seeing is 'C' complaining about things it doesn't know about.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    you use curly braces not ( ) to outline blocks, and you should have else if (..)

    solved my problem

    When I run it it says this on there
    Code:
    "ch2 - Debug" uses an invalid compiler. Probably the toolchain path within the compiler options is not setup correctly?! Skipping...

    I figure out my last problem but a new one occured. I would appreciate it for any help

    Can you create a new C++ console project, and copy/paste your code into a new source file inside the new project?

    Did you mess around with any of the options when you ran the Codeblocks installer? You should go to the global compiler/debugger screen and see what is currently set as the debugger, you should be able to navigate to mingw/bin/gdb.exe and select that if it is not already set. (The path will be something like that, I am just guessing right now)

    FYI: The debugger used by Code::Blocks in supporting Visual Studio in the command line program that needs downloaded/installed separately from the VS Compiler.

    I think this link is to the correct tool; but, I am not sure.
