1. Declare the variables for the program. 

2. Take the input string from the user. 

3. Take the replacing character from the user.

4. Replacing the string. 

5. Print the string. 

6. End the program.

{
    //declaring the variables for the program
    char str[50], ch, i;
    
    //taking input string form the user
    printf("Enter any string: ");
    gets(str);
    
    //taking the replacing character from the user
    printf("Enter any character: ");
    scanf("%c", &ch);
    
    //Replacing the vovewls from the characters
    for(i=0; str[i]!='\0'; i++)
    {
        if(str[i]=='a' || str[i]=='e' || str[i]=='i' || str[i]=='o'

        {
            str[i] = ch;
        }
    }
    
    //Printing the output string from to the user after replacing the character
    printf("\nNew String (after replacing vowel with %c) = %s", ch, str);
    
    return 0;
}

#include<stdio.h>

#include<string.h>

int main()

{

//declaring the variables for the program

char str[50], ch, i;

//taking input string form the user

printf("Enter any string: ");

gets(str);
