Computer programming Assignment
1. Declare two integer arrays of sizes 10 each. Your task is to print the elements which are
common in both the arrays.
Sample Input:
a[]: 1,2,3,4,5,6,7,8,9,20
b[]: 2,4,6,8,10,12,14,16,18,20
Sample Output:
Common elements: 2, 4, 6, 8, 20
2. Write a program which will take a character array a[] of size 15 and a character array b[] of size
10 from the user. Also take an index from the user, and starting from the given index place array
b[] in array a[]. At the end, display a[].
Sample Input:
a[]: program
b[]: computer
Index: 3
Sample Output:
a[]: procomputer
3. Write a program in which you have a character array of size 50. Input array from the user. Then

  1. Write a program which will take choice (1 โ€“ 3) from the user in main(). For choice 1 call function1() , for choice 2 call function2() and for choice 3 end the program. Use switch case for handling user choice. The functions will perform the following tasks: function1() will take a number within its scope and print all the even numbers upto that number. function2() will take a number as argument from main() and print all the multiples of 3 upto that number.

Sample Input: 2 , 16 Sample Output: 3, 6, 9, 12, 15

  1. Write a program which will take an alphabet (small or capital) from the user in main() and pass it to a function previous_alphabet()****. The function will return the alphabet previous to the given alphabet to main(). Display the results in main(). After every output, ask whether the user wants to run the program again or not.
