$($Validating User Input$)$ Modify the program in Figure $3\mathrm{.}6$ to validate its inputs.

For each input, if the value is other than $1$ or $2,$ keep looping until the user enters

a correct value. Write sWrite single C statements to perform each of the following tasks:

a$)$ Input integer variable x with scanf. Use the conversion specification $\%$d$.$

b$)$ Input integer variable y with scanf. Use the conversion specification $\%$d$.$

c$)$ Set integer variable i to $1.$

d$)$ Set integer variable power to $1.$

e$)$ Multiply integer variable power by x and assign the result to power.

f$)$ Increment variable i by $1.$

g$)$ Test i to see if it$$s less than or equal to y in the condition of a while statement.

h$)$ Output integer variable power with printf.ingle C statements to perform each of the following tasks:
