Question

C++

Write a function named timesOfLetter that reads an array and returns the number of times of each lowercase vowel and each uppercase vowel appear in it using reference parameter.

• Write a function named timesOfNumber that reads an array and returns the number of times of each odd number, and each even number appear in it using reference parameter.

• Write a function named isChar() that determines the input is alphabetic or not during inputting.

• Write a function named isInt() that determines the input is a digit or not during inputting.

• Initialize the size of the arrays as 10.

#include <iostream>
using namespace std;

bool isChar (char c)
{
if ((c >= 65 && c <= 90) || (c >= 97 && c <= 122)) // ASCII value range for capital alphabets is 65 – 90 and for small alphabets is 97 – 122
return true;
else
return false;
}

bool isInt (char c)
{
if (c >= 48 && c <= 57) // ASCII value range for digits is 48 – 57
return true;
else
return false;
}

void timesOfLetter (char *array, int *l_vowel, int *u_vowel)
{
char c;

for(int i=0; i<10 ; i++){ // reading 10 alphabets from user

else

}

for(int i=0; i<10 ; i++){

if (array[i]=='A' || array[i]=='E' || array[i]=='I' || array[i]=='O' || array[i]=='U') // checking uppercase vowels
