then the function should be rearranged as

6, 2,10,8, 18

If an array of ten elements has initial content as : 8, 10, 1, 3, 17, 90, 13, 60, 16, 5 The function should rearrange the array as: 90, 13, 60, 16, 5, 8, 10, 1, 3, 17.

Q25.Write a program in C++ to use a function for replace the repeating elements in an array by 0 . Do not use parallel array. The order of the array should not change. (4) Eg : Array : 10 , 20 , 10 , 50 , 30 , 20 , 10 Result : 10 , 20 , 0 , 50 , 30 , 0 , 0 Q26. Write a program/function in C++ which accepts a integer array and its size as an arguments and prints the output (using nested loops) in following format : (4)

Example : if the array is having 1 2 4 5 7 Then the output should be 1 2 2 4 4 4 4 5 5 5 5 5 7 7 7 7 7 7 7 Q27. Write a program/function in C++ which accepts an integer array and its size as arguments/parameters and exchanges the values at alternate locations . (3) example : if the array is 8,10,1,3,17,90,13,60 then rearrange the array as 10,8,3,1,90,17,60,13
