For this project, you are tasked with creating a text-based, basic String processing program that performs basic search on a block of text inputted into your program from an external .txt file. After greeting your end user for a program description, your program should prompt the end user to enter a .txt input filename from which to read the block of text to analyze. Then, prompt the end user for a search String. Next, prompt the end user for the...
