Start with the program which simply prints what you type in.
Then you've got something to work with for the next step, say determining the case.
Post when you've got code, AND are stuck.

i already start with simple program,look like it easy, but when come to more complicated program, dont know what to do,
maybe its a late start for me to do programming, i am 33years old, taking online learning, with work and family...
So post your easy program, then tell us which step you think you need to do next, and where in the code it might go.
We'll be here to guide you.

Salem's guidance is really splendid. You need to try once more. You do have very simple inbuilt functions like isalpha(),toupper(),tolower() etc to serve your purpose which you have mentioned in your post.
