this is my c++ hw btw Now modify the lab so that it prompts the user to input a letter using cin statements, and that letter replaces the character you used to draw the picture in Lab 1. You'll prompt the user: "Please enter a letter" If the user enters a 'B' then the output would look like this: BBBBBBBBBBBBBBBBBB BB BBBBBB BBBBB BBBB BB BBB BBBB BB BB BBBB BBB BB BBBBBBBBBBBBBBBB BB BBBBBBBBBBBBBBBBBBBBBB BB BBBBBBB BBBBBB BBBB BBBBBBBBBB BB BB BB
