Write a program in a cpp file calledcountVowels_LastNameFistName.cppthat reads input from a text file (sentence.txt) and outputs the number of times eachlowercasevowel appears in the sentence to both thescreenandoutput_LastNameFirstName.txt.

Your program must contain the function belowcountVowelsthat return the number of times eachlowercasevowel appears in thesentence.

void countVowels(string str, int& aCt, int& eCt, int& iCt, int& oCt, int& uCt); (Noticethe return (void) and it should be the same. Also, no print statements in this function)

(Hint: that if str is a variable of type string, thenstr.at(i)returns the character at the ith position. The position of the first character is 0. Also, str.length() returns the length of the str, that is, the number of characters in str.)
