Question

Write an algorithm (flowchart OR Pseudocode) for the following problem

Take input character from the user unless he enters '$'. Thereafter display how may vowels were entered by the user. Also display the number of each vowel ('a', 'e', 'i', 'o' and 'u') separately.

For example if the user enters B

a

b

e

c

o

o

d

i

u

g

o

a

l

$

Then we have the output below:

#A=2

#E=1

#I=1

#O=3

#U=2

Answer 1

The algorithm ( pseudo code ) for the problem is given below:

start

count=0 // initialize total vowel count as 0

ac=0,ec=0,ic=0,oc=0,uc=0 // initialize count for a e i o u respectively

while (True)

{

ch = input () // takes the input from user

if (ch== "$")

break    // if input is $ then exit loop

else if(ch == "a") // this section check for "a"

count=count+1 // total count is incremented if the character entered is "a"

ac=ac+1   // count of "a" is incremented

else if(ch == "e") // this section check for "e"

count=count+1 // total count is incremented if the character entered is "e"

ec=ec+1 // count of "e" is incremented

else if(ch == "i")   // this section check for "i"

count=count+1 // total count is incremented if the character entered is "i"

ic=ic+1 // count of "i" is incremented

else if(ch == "o")    // this section check for "o"

count=count+1   // total count is incremented if the character entered is "o"

oc=oc+1    // count of "o" is incremented

else if(ch == "u")   // this section check for "u"

count=count+1   // total count is incremented if the character entered is "u"

uc=uc+1 // count of "u" is incremented

}

print ( "Total number of vowels :" , count) // print total count

print("#A :" , ac ,"\n #E : ", ec,"\n # I : ", ic,"\n #O : ", oc,"\n #U : ", uc) // prints the individual count of each vowel
