Hello, I am new to programming and new to this forum. I am in the process of writing a calculator program and I know i have to use a switch statement to jump to either a multiplication, division, addition or subtraction function if the characters "*/+-" are used. How do i set up a switch statement to pick up any of these characters out of a string such as *8 (multiply 8) and take that 8 to a multiplication function where it will be solved and return a value
Thank You
Search the web for things like reverse polish notation and shunting yard algorithm.

This is a recurring assignment, take a look at the Shunting-yard algorithm. It will show you everything you need.
EDIT: Too slow.

You need to stop and think about how you would do it on paper. How are you writing your lines of input?
<operator> <N1> <N2>
<N1> <operator> <N2>
Then, make a program that can read the pieces you need from a line of text. There is a FAQ on getting input, but something simple like scanf should get you started.
Give it a shot, post your code when you are stuck, along with the errors/problems you are having.
Quzah.
Hope is the first step on the road to disappointment.
