复制字符串中的元音的程序
给定一个字符串“str”,任务是复制这个字符串中的元音。
例子:
Input: str = "geeks"
Output: geeeeks
Input: str = "java"
Output: jaavaa
方法:使用循环迭代字符串。检查字符是否是元音并复制它。返回
然后打印结果字符串。
下面是上述方法的实现:
C++
// C++ program for printing string
// with duplicate vowels
#include
using namespace std;
// Function to check for the Vowel
bool isVowel(char ch)
{
ch = toupper(ch);
return (ch == 'A' || ch == 'E'
|| ch == 'I' || ch == 'O'
|| ch == 'U');
}
// Function to get the resultant string
// with vowels duplicated
string duplicateVowels(string str)
{
int t = str.length();
// Another string to store
// the resultant string
string res = "";
// Loop to check for each character
for (int i = 0; i < t; i++) {
if (isVowel(str[i])) {
res += str[i];
}
res += str[i];
}
return res;
}
// Driver Code
int main()
{
string str = "helloworld";
// Print the original string
cout << "Original String: "
<< str << endl;
string res = duplicateVowels(str);
// Print the resultant string
cout << "String with Vowels duplicated: "
<< res << endl;
}
Java
// Java program for printing string
// with duplicate vowels
import java.util.*;
class GFG
{
// Function to check for the Vowel
static boolean isVowel(char ch)
{
ch = Character.toUpperCase(ch);
return (ch == 'A' || ch == 'E' ||
ch == 'I' || ch == 'O' || ch == 'U');
}
// Function to get the resultant string
// with vowels duplicated
static String duplicateVowels(String str)
{
int t = str.length();
// Another string to store
// the resultant string
String res = "";
// Loop to check for each character
for (int i = 0; i < t; i++)
{
if (isVowel(str.charAt(i)))
res += str.charAt(i);
res += str.charAt(i);
}
return res;
}
// Driver Code
public static void main(String[] args)
{
String str = "helloworld";
// Print the original string
System.out.println("Original String: " + str);
String res = duplicateVowels(str);
// Print the resultant string
System.out.println("String with Vowels duplicated: " + res);
}
}

输出:
Original String: helloworld
String with Vowels duplicated: heelloowoorld
