Program to accept Strings starting with a Vowel

Given a string str consisting of alphabets, the task is to check whether the given string is starting with a Vowel or Not.

Examples:

Input: str = "Animal"
Output: Accepted

Input: str = "GeeksforGeeks"
Output: Not Accepted

Approach:

  • Find the first character of the string
  • Check if the first character of the string is a vowel or not
  • If yes, print Accepted
  • Else print Not Accepted

Below is the implementation of the above approach:

          || str[0] == 'I' || str[0] == 'i'
          || str[0] == 'O' || str[0] == 'o'
          || str[0] == 'U' || str[0] == 'u'))
        return 1;

void check(string str)
{
    if (checkIfStartsWithVowels(str))
        cout << "Not Accepted\n";
    else
        cout << "Accepted\n";
}
  
// Driver function
int main()
{
    string str = "animal";
    check(str);
  
    str = "zebra";
    check(str);
  
    return 0;
