Answer 1

You are very welcome, yes I am not native English speaking myself, but the positive side is we learn to code and increase our vocabulary as we go, at the same time : )

Answer 2

Hello there ...

It seems you have mistaken writing C++ code in a C code. The `cout` is an output stream of C++, it is not available in C language. Use `printf` function if you want to print something to the screen in C language. Or alternatively, move the code into a new C++ code, but remember to `include <iostream>` in the C++ code if this is your choice (discard `#include <stdio.h>`).

And in the "4" code above a little correction for this line:

`cout ("b="<<b<< "\n" );`

Should be written as follows, notice the removal of parentheses and use of `<<` (insertion) operator :

`cout << "b=" << b << "\n" ;`

Please confirm for any uncertainty, I am here to help.

P.S. Reference for `printf` function:

Hello ... sorry for delays ...

Alright, seems like I was a bit unclear in my previous suggestion - I just visited your profile and see you are starting out with C, not C++.

I see you updated your code, and tried to use `printf` function, understand since it's a function, we call them by their name and parentheses, which wraps the arguments to pass (if any). So just forget what I gave you before with the `cout` and << operator because we're using C language.

Fix for code "4" and "2" are similar, all we need is just call `printf` function with the format specifier and values to print, all wrapped within parentheses.

● In code "4"
printf("b = %d\n", b);

● In code "2"
printf("a = %d\n", a);

Syntax:
printf("format-specifier", argument-list)

format-specifier is a string that specifies how the values in argument-list are supposed to be printed. I suggest you to read the reference linked in my previous response for further details about printf function.

You are welcome for any further enquiries : )
