How can I extract data and load into variables from a string.

[ahmad2005]

I'm a getting string line from a serial output. Now I wanna extract this string and load the substrings into the different variables. How can I do this?
For example, I have a string line something like "=>Data1=10&Data2=20&Data3=30". Now I wanted to load these data values into three variable like variable1=10, variable2=20, and variable3=30.

How could be the best way to do this. Can anyone give me an example code in C ?

Look at the 'strtok' function. It is for searching for characters throughout a string and dividing it at that point (Tokenizing). If you loop the function until it returns nul (meaning it has reached the end of the string) and use '=' as the search character it will return a pointer to each of the values in turn, no matter how long the string is.
