In c++

No multiple return statements in a function. At most,1 return statement in a function is allowed

.No exit() function is allowed either.

No global variable is allowed. Constants are ok.

No reference to cin or cout in a function unless it is allowed explicitly in the question

Please include code that shows how you have tested these functions

This is to practice the usage of pointer.

Write a function named duplicateWithoutBlanks that accepts a C-string of characters. It will create a new C-string using new operator and return a copy of that given string without any blank in the duplicate string.

For example, if it is given this string of Hello, World!, it will return a new string containing Hello, World! Note: It only uses pointer notation. Please show how this function is being used and tested.

Oh! can you at least work on that since that's only I got for example and the question.
