Answer to Question #117733 in C++ for ayza

Question

Write a program to pass a reference of a character array in a function, store it in a pointer variable and then calculate the total characters and vowels in the array.

Answer 1

#include <iostream>
#include <string>
using namespace std;

void countChars(char (&arr)[8]) {
  string vowelsArr = "aeiou";
  char *ptr = arr;

  int total = 0;
  int vowels = 0;

  for (int i = 0; i < 8; ++i) {
    ++total;
    if (vowelsArr.find(*ptr) != -1) {
      ++vowels;
    }
    ++ptr;
  }

  cout << "total: " << total << endl;
  cout << "vowels: " << vowels << endl;
}

int main() {
  char a[] = {'d', 'f', 'a', 'x', 'e', 'r', 'b', 'u'};

  countChars(a);
}
