Answer:
Following is the program in the python language
s="Hellooo" #string initialization
k=0 # variable declaration
vowel_count=0 #variable declaration
while k<len(s): #iterating the loop
c1=s[k] #store in the c1 variable
if c1=='a' or c1=='e' or c1=='i' or c1=='o' or c1=='u': #check the condition
vowel_count= vowel_count +1; # increment the variable vowel_count
k = k+1
print(vowel_count) #display
Output:
4
Explanation:
Following is the description of program
- Create the string "s" and store some characters on them.
- Declared the variable "k" and initialized 0 on them .
- Declared the variable "vowel-count" and initialized 0 on them .
- Iterating the while loop ,inside that loop we shifted the string "s" into the " c1" variable and checking the condition in the if block by using or operator if the condition is true then it increment the "vowel_count" variable by 1 .
- Finally outside the loop we print the value of "vowel_count".
