Class XI
1.
WAP to enter a line in an array containing
alphabets, digits and special symbols and display them in separate line with
proper heading. Example-
Input Line: Every student23 has^$ equal @# right to
educa436tion.
Output should be:
Alphabets: Every student has equal right to education
Digits: 23436
Special Symbols: ^$@#
2.
WAP to enter any two string from user and check
whether both strings are equal or not? (Don’t
use string function)
3.
WAP to generate any 10 random numbers in
the range of 100 to 1000 and get the sum of all these numbers. Suppose the sum
of all the numbers are X. Now add all the digits of X and obtain Y. Now check
whether Y is Prime or not? If it is a prime number than find its cube else find
square.
4.
WAP to print the following series-
a.
Look at this series: 7, 10, 8, 11, 9, 12, ... …n
b.
Look at this series: 6, 11, 21, 36, 56….n
c.
Look at this series: 1, 6, 13, 22, 33…n
5. Write a program to display the
ASCII code of a character entered by the user.
6. Write a program to print
Fibonacci Series i.e., 0 1 1 2 3 5 8….till n.
7. Define a function named
Largest(int, int , int) which should take any three integer values from the
user and must return the largest integer. If the largest integer is even than
display its half or display its square root.
8. Write a program which should
take any string from user and check whether the string is palindrome or not. (A
string is palindrome if it has same sequence of characters after reversing as
it was earlier.)
9. Write a program to accept any
four digit number from user and check whether the number is Armstrong or not.
10.
Write a
program to accept a line form user of 200 character and reverse the sequence of
characters in the line.
11.
WAP to enter any two string of same size and
check total number of uppercase and lowercase letter is both line after
concatenation.
12.
WAP to enter any 2 number from user and display
and any 5 random numbers between them.
13.
WAP to generate any three digit random number
and check whether the number is prim or not. If number is prime then reverse it
otherwise find the product of the all the digits in the number.
14.
WAP to define an array to store any 20 integer
values and display the square root of all the even numbers and half of all the
odd numbers.5- Marks
15.
WAP to define an array to store any line of 100
characters and count total number of vowels in the given line.-5 Marks
16.
WAP to define an array to store a line of 100
characters and convert all the spaces into character ‘@’ and digits in ‘#’.
5-Marks
17.
WAP to define an array to store any 10 integers
and swap first two values with last two values. 5 Marks
Example- Array is:
1 2 3 4 5 6 7 8 9 10
Output
should be:
10 9 3 4 5 6 7 8 2 1
