The following code should swap the vowels between two input strings. Most of the setup code is complete, the remaining task is to create a function named 'swap_vowels which takes as input two pointers-to-char. The function should swap the vowels between two input strings. If the strings do not contain the same number of vowels, then only the corresponding vowels will be swapped (see example output). The function should return an integer indicating how many vowels were swapped. Modify the given code as requested. Example Output Enter a string: perseverance Enter another string: curiosity pursivorince cereesaty
