This is for a C lab that I have for class; if anyone can help I'd be grateful.

4: .Make a new folder for lab4 write this in c. create a header file functions4.h with the prototypes for the two functions shown below Include a preprocessor wrapper 1. void splitAlpha const char *original, chalower, charupper The variables original, lower, and upper are pointers to null-terminated strings (character arrays).The function splitAlpha should copy the lowercase letters from original to lower, and the uppercase letters from original to upper. The memory areas pointed to by lower and upper are assumed to be large enough to hold the number of characters that need to be moved. The string original may contain non-alphabetic characters The contents of original should not be changed. For example, if original contains "The symbol for Intel is INTC." After the function completes, lower should contain "hesymbolforntelis" (remember to put in the null character) and upper should contain "TIINTC" (null character at the end)
