[me001]

does anyone know hwo i could fix this problem? the error message reads that

setName(newFirstname[], newLastname[]);
expected primary-expression before ']' token

If you are using the new operator, you are expected to put a number in the brackets to indicate the size of the array. Are Lastname and Firstname classes? Structs? Or are they variables?

[me001]

they are members within in a class. so if i initialize the char array to 40 for each within in the class, then i have to do it then too??

IF they already exist, then you shouldn't be using the new operator. new will create a new variable rather than using the one you already have.

setName(newFirstname[], newLastname[]);
 

If this is a function prototype:
1) what is the return type?
2) what are the types of the arguments? All you say is that they are arrays but you don't say arrays of what.
