Write an algorithm to compute the area of a circle (area = * radius* radius), or circumference of a circle (circumference=2 * * radius) or a triangle (area = 1/2 x base x height) based on the input by the user (i.e. either C, F or T respectively). Display Invalid User Input if the user entered other letters. Once you have completed the algorithm, implement the algorithm using C++.

Write an algorithm to compute the area of a circle (area = 7 * radius" radius), or circumference of a circle (circumference=2*77* radius)or a triangle (area=1/2 x basex height) based on the input by the user (i.e. either 'C', 'F' or 'T' respectively). Display "Invalid User Input" if the user entered other letters. Once you have completed the algorithm, implement the algorithm using C++
