Write a program that asks the user for an integer value gre ater than zero. It will verify that the user has entered a valid value and then try to allocate enough space using malloc for an array of n elements where n is the integer they ent ered in the first step. Your program should make sure that the allocation worked and then call a function named fillArray that uses a for loop and the square brackets operator to fill the arr ay with the first n odd numbers. For example, the variable that is zero elements away from the base address should get the value 1, the value that is 1 element aw ay from the base address should get the value 3, and so on (see the screen shot below). A fterwards, call another function called printDown that uses anot her f or loop and the square brackets operator to print them in reverse order separ ated by new lines. Print a line that has 3 asterisks ("*) in it by itself. Finally, call another function called print Up that uses another for loop that prints all of the array elements in order but without using the square bracket operator. To do this, you will need to use only the derefere nce operator and point er ar it hmet ic (i.e., increment or decrement the pointer).

Transcribed Image Text:Write a program that asks the user for an integer value gre ater than zero. It will verify that the
user has entered a valid value and then try to alloc ate enough space
elements where n is the integer
using malloc for an array of n
they entered in the first step.
Your program should make sure that the allocation worked and then call a function named
fillArray that uses a for loop and the square brackets operator to fill the array with the first
n odd numbers. For example, the variable that is zero elements away from the base address should
get the value 1, the value that is 1 element aw ay from the base address should get the value 3, and
so on (see the screen shot below). A fterwards, call another function called printDown that uses
anot her f or loop and the square brackets operator to print them in reverse order separated by
new lines.
Print a line that has 3 as terisks (**) in it by itself. Finally, call anot her function called
that uses another for loop that prints all of the arr ay elements in order but without using the
square bracket operator. To do this, you will need to use only the derefere nce operator and
point er ar it hmet ic (i.e., increment or decrement the pointer).
Don't forget to free the memory before the program ends.
