Can some one please help!!!!!

Im new to c++ ive installed code blocks compiler and completed the hello world prog and varables section so I thought I would try other progs from online from c++ programming site to get an understanding of c++ but every prog I try all I get is different errors for every line, this are the sort of errors
from the compiler on virtually every prog I try:

C:\Users\Jason\Programming\Code\main.cpp|1|error: iostream.h: No such file or directory|
C:\Users\Jason\Programming\Code\main.cpp|4|error: '::main' must return 'int'|
C:\Users\Jason\Programming\Code\main.cpp||In function 'int main()':|
C:\Users\Jason\Programming\Code\main.cpp|6|error: 'clrscr' was not declared in this scope|
C:\Users\Jason\Programming\Code\main.cpp|8|error: 'cout' was not declared in this scope|
C:\Users\Jason\Programming\Code\main.cpp|8|error: 'endl' was not declared in this scope|
C:\Users\Jason\Programming\Code\main.cpp|9|error: 'cin' was not declared in this scope|
||=== Build finished: 6 errors, 0 warnings ===|


Every day I try to do a little and learn some thing new but every day Im feeling like giving up because I get this from the compiler. What is the not "declared in this scope" is my compiler not configured correctly. Ive gone through the setup guide on this site and followed it exactly. Please help!!!!!

Unfortunately, many tutorials out there, possibly including some of the old ones on this website, are outdated or plain wrong. I suggest that you work through a book like Accelerated C++.

This is in old pre-standard header that is not available any longer the correct replaced by

Code:

---

#include <iostream>

---

Note the missing file extension.

In a C++ program main function must be defined to return an int

Code:

---

int main()

C:\Users\Jason\Programming\Code\main.cpp|6|error: 'clrscr' was not declared in this scope|

The function clrscr() is not a standard function an is probably not available with your compiler. To fix this error delete all calls to this function.

These errors are because you are not properly scoping functions in the standard namespace. To fix these errors you will either need to use the scope resolution operator (:: ) in front of each call to these functions (std::cout) or by the using namespace std; declaration prior to your main function.

The stuff here seems to be more consistent/up to date:

C++ Language Tutorial - C++ Documentation

Altho there is nothing about compiling there, it does say the code should work with any C++ compiler.

I'm sure it's frustrating at first if you are new to programming. Hang in there and don't be afraid to ask questions.

Thank you lazerlight, You are one pretty programmer!! and every one who has posted you are a real help.

Thank you, you are one pretty programmer!!

One additional advice which is off-topic only at first sight and which is not at all meant as an offence: Try to work on the way you're writing. Grammar rules also apply to posting on the internet. Use punctuation, spell out your words instead of using sms speak, use paragraphs, think about what you want to say and how to express that before-hand.

Programming languages *need* strict grammar rules, because your CPU's capabilities of interpretation are very limited. If you can't even put enough effort to express yourself properly in a natural language, you will never learn a programming language to a high extend.
