PROGRAM-10
Program to convert the case of inputted sentence and arrange the words in alphabetical order.
ALGORITHM
Step1-Start.
Step2-We have made parameterized constructor and the parameter is
String str1and we have assigned str to str1.
Step3-Input the String in the function getdata.
Step4-We have convert the case of the String and find out the length of
the String in the function proceed.
Step5-We have done type casting and stored the character in c we have
found the character of the string in ch as well as the next character
of the string in ch1.
Step6-We have checked the condition i.e. (ch== ‘’||ch1== ‘c’).If this
condition found true then go to Step7 .
Step7-We have taken out the character of the string and check the condition i.e.(ch!= ‘’).If this condition found true then go to step-8.
Step8-We have taken the character of the String in String s
Step9-Apply break
Step10-We have print the arranged string in the function disp.
Step11-Use inheritance and we have made main function in class alph
Step12-We have called the function made above and we have arrange
the string in alphabetical order
Step13-End

PROGRAM-11
PROGRAM TO ARRANGE GIVEN ARRAY IN
ODDS AND EVEN ORDER.
ALGORITHM
Step1- Start.
Step2-Initialise the array i.e. int a [ ] =new int[10].
Step3-Now declare the constructor arr ( ) and within it
initialize 0 to all the values of array.
Step4-Now make another function input ( ).
Step5-Initialise a loop from 0 to 9 i.e. for(x=0; x<10; x++).
Step6-Within this loop accept the number by the user and store number in a[ ].
Step7-Now make another function arrange ( ).
Step8-Within the function initialize a loop from 0 to 9 i.e. for(x=0; x<10; x++) and initialise temp=0.
Step9-Run another loop from 0 to 8 i.e. for(y=0; y<9; y++) and check if (a[y] %2==0 && a[y+1%2! =0).If true then goto step 10.
Step10-Initialise temp=a[y], a[y] =a[y+1] and a[y+1] =temp and then close all the loops.
Step11-Initialise another loop for(x=0; x<10; x++) and print the values of a[x].
Step12-End
