Consider the following C$++$ code:

$//$ This C$++$ program prints "You Pass" if a student's average is

$//60$ or higher and prints "You Fail" otherwise

#include

using namespace std;

int main$()$

$\{$

float average; $//$ holds the grade average

cout $$ "Input your average:" $$ endl;

cin $>>$ average;

if $($average $>60)$

cout $$ "You Pass" $$ endl;

if $($average $<mtext></mtext><mn>6</mn><mn>0</mn><mi>)</mi>$

cout $$ "You Fail" $$ endl;

return $0$;

$\}$

Exercise $1$: Use if$-$else$-$if statement to modify the C$++$ program above to allow the following categories: Invalid data $($data above $100),$A$$ category $(90100),$B$$ category $(8089),$You Pass$$ category $(6079),$You Fail$$ category $(059).$ Save the C$++$ program as Lab$3\_$p$3$a$.$cpp

Part $2$: Use nested if statements to rewrite your C$++$ program in exercise $1.$ Save the program as Lab$3\_$p$3$b$.$cpp

Part $3$: Use logical operators to connect more than one relational expression to rewrite your C$++$ program in exercise $1.$ Save the C$++$ program as Lab$3\_$p$3$c$.$cpp

Consider the following code:
