4. Write a C Program to print Reverse of a given number
AIM:
Write a C Program to print Reverse of a given number
ALGORITHM:
1. Start the program
2. Ask the user to enter any number.
3. Declare and initialize another variable reversed with 0, where reversed an integer
variable.
4. Get the last digit of the given number by performing the modulo division (%) and
store the value in last_digit variable, likey last_digit= number % 10.
5. Multiply reversed by 10 and add last_digit, like reversed = reversed*10 + last_digit.
6. Divide numbered by 10, like numbered/10.
7. Repeat the steps 3 to 5 till numbered is not equal to (or greater than) zero.
8. Stop the program

5. PROGRAM:
RESULT:
Thus, a C Program for performing reversal of a number is completed and run
successfully

6. Write a C Program to Print the Odd and Even Series of a N Numbers
AIM:
Write a C Program to Print the Odd and Even Series of a N Numbers
ALGORITHM:
Step 1: Start
Step 2: [ Take Input ] Read: Number
Step 3: Check: If Number%2 == 0 Then
Print : N is an Even Number.
Else
Print : N is an Odd Number.
Step 4: Exit

7. PROGRAM:
RESULT:
Thus, a C Program for printing the odd and even series of a N numbers is completed
and run successfully

8. Write a C Program to get a string and convert the lowercase to uppercase and vice--versa
using getchar() and putchar().
AIM:
Write a C Program to get a string and convert the lowercase to uppercase and vice--
versa using getchar() and putchar().
ALGORITHM:
Step 1: Start the program
Step 2: Read char size of array str[15] and int i
Step 3: Specify the condition for while loop
Step 4: If string is capital
print str[i]+32
Else
Print s[i]-32
Step 5: increment the character i++
Step 6: print the string
Step 7: Exit the program

9. PROGRAM:
RESULT:
Thus, a C Program for getting a string and convert the lowercase to uppercase and vice--
versa using getchar() and putchar().s completed and run successfully

10. Write a C Program to input a string and find the number of each of the vowels appear in the
string.
AIM:
Write a C Program to input a string and find the number of each of the vowels appear in the
string.
ALGORITHM:
1. Start the program
2. set the count to 0
3. Loop through the string until it reaches a null character.
4. Compare each character to the vowels a, e, i o, and u.
5. If both are equal
6. Increase the count by one.
7. Print the count at the end.
8. Stop the program

11. RESULT:
Thus, a C Program for input a string and find the number of each of the vowels appear
in the string.is completed and run successfully

12. Write a C Program to Printing the reverse of a string
AIM:
Write a C Program to Printing the reverse of a string
ALGORITHM:
1. Start the program
2. Declare all the variables ( integer and character type )
3. Enter the string to be reversed
4. Find out the length of string
5. Swap the position of array element using loop
6. Store the swapped position
7. Print the reversed string as console output
8. Stop the program

13. PROGRAM:
RESULT:
Thus, a C Program for performing reversal of a string is completed and run
successfully
