copying-paste your errors which you are getting will be helpful. paste your errors or tell me what type of error are you facing ?

here are the errors that appear.

ok. I will firstky try to remove the errors in the code, then will explain you if you really want to know the reasons.

  1. change line #1 to #include<iostream>
  2. replace void main() with int main()
  3. write a statement "return 0;" (without quotes) at the end of your code, so as to return an integer because main() expects you to return an integer.

  4. EXIT_SUCESS is also okay here, but you can use return 0; also if you want.

make all these changes, and post your doubts here, if you have any. hope it helps. thanks.

it went well but there is another error after i apply some changes

13 C:\Users\CBS NETZONE\Documents\C++\main.cpp `cout' undeclared (first use this function)   (Each undeclared identifier is reported only once for each function it appears in.) 

Use std::cout instead, unless you added the line using namespace std; at the top of your code (after the #includes).

I will say that std is a "thing"(don't know how to explain this word) in which many things are declared. like cout, cin,etc for an instance. you have to mention it's declaration place before using it. so two ways are there.
1. use std::cout at each place instead of cout.
2. Add using namespace std on the top before using any cout, cin.

hope it helps! thanks.

@ nitin1

std is a namespace that all of the standard c++ functions and classes are in. A namespace is just another level of orginizing your code. You can equate it to the file cabinet metaphor. The function is a piece of paper. The file the function is in is a folder. The namespace is the drawer that the folder is in. Your project is the file cabinet that contains it all.

awesome metaphor!!
