Please write in C Programming;

$1-$ Given the following:

int arr$[200]$;

Write a for loop that populates the array with the

following sequence:

$4,8,12,16,20,$dots..,$796,800,804$

$2-$ Given the following sequence:

$036912$dots$30$

Declare an array of integers called "multi" of the length

required to store the above sequence. Declare the

required variable$($s$)$ and write a for loop that stores the

above values in the array.

$3-$ Declare a $10$x$10$ array and set the array elements to the

following values.

$0,1,2,3,4,5,6,7,8,9$

$10,11,12,13,14,15,16,17,18,19$

Declare the required variables and write the code

required to initialize and print out all the array value

with one row per line of output.

$4-$ Given an array with $200$ rows and $800$ columns. The

array already contains data. Write the code required to

output the sum of all the elements in the last $50$ rows.

$5-$ Write the function definition of a function named "sale"

as follows: The function accepts two arguments of type

float, one is the item total and the other is the sale tax

percentage $($out of $100\%).$ The function should return

the amount of tax calculated for the purchase.

$6-$ Write the function definition of a function that

repeatedly asks for the user's age and when the age

entered is higher than zero and less than $150($age

should be an integer$),$ then the function should return

that age.

$7-$ Write a function named "robot". This function has two

integer parameters named "forward" and "reverse" and

a return of type integer. If the value passed to forward is

$1$ and to reverse is $0$ then the return should be $127.$ If

the value passed to forward is $0$ and to reverse is $1$ then

the return should be $-127.$ If both are $0$ or both have

nonzero values, then the return should be $0.$
