hi its been 2 years since the last time i program in c and this is my first after 2 years. So i'm not that familiar anymore to the syntax in c(especially i'm already programming in java). So my problem is, i don't know if i did something syntactically wrong in my code. But an error occurred and it said that: "invalid operands to binary +" to the line..

valString += tempExpName;

//valString and tempExpName are both of type string. I already included stdlib.h in my code, but it won't removed the error.

--please could someone explain to me what is really wrong? Thanks :)

The problem...your trying to add two char pointers...I think.

Could you post the rest of the code.

thanks. I realized it after i posted it. I just can't add two char pointers/strings. I have to used the function strcat(str1, str2), right?

Well if you want to append one string onto another, then yes use strcat.
