When I run my program and enter the next temper such as "T", it will still show me the results as if I entered "C".

How do I fix this?

Your logical expressions are wrong.

You cannot use
shape==Rr

You must use
shape==R shape == r

if(shape==Cc)

i incorrect.

Thi is what it check when it run thi if

if (shape is equal to the character C OR if c exists)

Since c always exists, this if function will always return as true regardless of what shape is and, as of result, always run thi if. The correct way to do this is

if(shape==C shape==c)

else if (shape==Tshape==t)

else if (shape==Rshape==r)

You are also missing a fallback case (the final else), you can try adding after the last "else if"

else

cout << "Incorrect character entered\\n";

Fix thi for all of your ifs and the code should work correctly. Good luck!

Hopefully all the C family will go away.
