接受以元音开头的字符串的程序

给定由字母组成的字符串str ，任务是检查给定的字符串是否以元音开头。

例子：

Input: str = "Animal"
Output: Accepted

Input: str = "GeeksforGeeks"
Output: Not Accepted 

方法：

• 查找字符串的第一个字符
• 检查字符串的第一个字符是否为元音
• 如果是，打印 Accepted
• 不接受其他打印

下面是上述方法的实现：

CPP

// C++ program to accept String
// starting with Vowel
 
#include 
using namespace std;
 
// Function to check if first character is vowel
int checkIfStartsWithVowels(string str)
{
 
    if (!(str[0] == 'A' || str[0] == 'a'
          || str[0] == 'E' || str[0] == 'e'
          || str[0] == 'I' || str[0] == 'i'
          || str[0] == 'O' || str[0] == 'o'
          || str[0] == 'U' || str[0] == 'u'))
        return 1;
    else
        return 0;
}
 
// Function to check
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;
}

Java

// Java program to accept String
// starting with Vowel
class GFG
{
 
// Function to check if first character is vowel
static int checkIfStartsWithVowels(char []str)
{
 
    if (!(str[0] == 'A' || str[0] == 'a'
        || str[0] == 'E' || str[0] == 'e'
        || str[0] == 'I' || str[0] == 'i'
        || str[0] == 'O' || str[0] == 'o'
        || str[0] == 'U' || str[0] == 'u'))
        return 1;
    else
        return 0;
}
 
// Function to check
static void check(String str)
{
    if (checkIfStartsWithVowels(str.toCharArray()) == 1)
        System.out.print("Not Accepted\n");
    else
        System.out.print("Accepted\n");
}
 
// Driver code
public static void main(String[] args)
{
    String str = "animal";
    check(str);
 
    str = "zebra";
    check(str);
}
}
