Answer:

def is_vow(c):

# this compares vowel with

# character 'c'

return ((c == 'a') or (c == 'e') or

(c == 'i') or (c == 'o') or

(c == 'u'));

# function to print resultant string

def removeVowels(str):

# print 1st character

print(str[0], end = "");

# loop to check for each character

for i in range(1,len(str)):

# comparison of consecutive

# characters

if ((is_vow(str[i - 1]) != True) or

(is_vow(str[i]) != True)):

print(str[i], end = "");

# Driver code

str= " geeks for geeks";

removeVowels(str);

Answer:

Explanation:

#include<stdio.h>

// function will check for a vowel

int checkVowel(char ch)

{      

if((ch=='A') || (ch=='E') || (ch=='I') || (ch=='O') || (ch=='U') || (ch=='a') || (ch=='e') ||    (ch=='i') || (ch=='o') || (ch=='u'))

               return 1;

 else

              return 0;

}

int main()

{

       char str[100];

       printf("Enter string : ");

       scanf("%[^\n]",str);

       int i,strlen,consecutiveVowel=0;

       for(i=0;str[i];i++);

       strlen=i;

       for(i=0;i<strlen-1;i++)

       {

             if(checkVowel(str[i]))

              {

                  if(checkVowel(str[i+1]))

                  {

                   consecutiveVowel++;

                  // to get the position of consecutive vowels

                   printf("positions of consecutive vowels :%d  &  %d  \n", i+1,i+2);

                  }

               }

          }

if (consecutiveVowel==0)

           printf (" Not found");      

  else

printf("Total Consecutive Vowel = %d\n",consecutiveVowel);

       return 0;
