I am in a C programming class and I am having trouble with my code for one of the questions as I am unsure on how to write it. The question is: Write a subroutine that takes four strings pointers as parameters: pstrDestination, pstrSource, pstrToFind, pstrReplaceWith. The subroutine should copy the source string into the destination string (and terminate) but it should replace all instances of pstrToFind with pstrReplaceWith. Assume the destination string is large enough to hold the source. For example source="I love Star Trek and I love Star Wars", find=”love”, replace “really love”, would be copied as “I really love Star Trek and I really love Star Wars”.
