Question 1 Question 2 Question 3

C++ Program only use array and loop and if/else condition.. don't use interception or vector because I am a beginner so make program only beginner level. Please add comments and also add proper output message "what programmer should ask the user".

# create an array with size 12. Check whether this array is a palindrome or not. Palindrome means whether we see the elements from start to end or end to start if both are same then array is a palindrome. Please enter 12 numbers for array one|| 12 54 25 62 -10 95 23 45 11 25 16 12 Array elements from left to right 12 54 25 62 -10 95 23 45 11 25 16 12 Array elements from left to right 12 16 25 11 45 23 95 -10 62 25 54 12 | Array is not a palindrome. # create three arrays, array one of size x, array two of size y and array three of size x + y. we can say array one has 10 elements, array two has eight then array three will have eighteen elements. Take input for array one and two from user, merge array one and two in array three, as first copy array one elements in array three and then copy array two elements in array three. Please enter 10 numbers for array one 12 4 5 8 7 2 -10 9 13 5 Please enter 8 numbers for array two 25 41 8 7 56 12 63 54 Elements in array three are 12 4 5 8 7 2 -10 9 13 5 25 41 8 7 56 12 63 54 # create an array of size 15, get input from the user. You have to find that if array has any duplicate value or not, if it has write array has duplicate values, otherwise write array has all unique values. Please enter 15 numbers for array 12 4 5 8 7 2 -10 9 13 5 41 21 24 Array has duplicate values. 8
