Write c$-$ program that store ten marks entered from the key board in an array of integers, and then find the following: $1$ marks

Average for the marks greater than $80\mathrm{.}1$ marks

If the average of the marks greater than $80$ is less than $90$ then we will add bonus to each mark as follows : $3$ marks

a$)$ If the mark is greater than $80$ the bonus is $2$ marks

b$)$ If the mark is less than or equal $80$ the bonus is $4$ marks

$10$ :

$80.$

$90,$:

$.80.$

$.804.$
