Hi,

Write code to solve the following problem. Define a function that takes a String as a parameter and returns an integer value. The function need to loop through each character in the input string to find a value of “x”. If a value of “x” is found in the string then return the position within the string where “x” is found else return -1.

Hi Stella,

Just a quick question about your problem. Is "x" a string or a character?

    Ok I usually would use Linux to program because there is a compiler (gcc), but I need to use Windows

    will compile the C language. I have tried Microsoft Visual C++ Express 2008 but I find it to be way
    too bulky and hard to use. The command-line compiler is similar to gcc I guess, and it creates
    executable files for Windows, but the compiler in the actual program compiles C++ but not C for some
    reason. And it will only compile files in projects, not standalone files. In my....

    Lets start this thread and find out more about our coding roadmap! The first code I ever wrote was
    on a BBC Micro Computer that came with its on embedded ROM-OS and ROM-BASIC - this was when I was in
    my 5th grade (1990-91). It was pretty powerful for those times, offering decent 16-color graphics
    and a powerful sound engine behind it (using normal computer speakers) - that PCs never achieved.
    In about an year or so, I shifted over to PCs coz the lack of applications for the BBC Micro was
    getting to me (all appz for it had to be either written in Assembly or that ROM ....
