So today I'm going to tell you how what the code from yesterday means. Opposed to going line by line, explaining everything, I'm instead just going to explain what the major parts of the program mean.
First, "cin" means console input. This is where people type into the console.
"if(selection == 1)" means that if the user inputs one as their selection, the following code will execute.
"cout" means console output. This is all of the stuff that gets displayed in the console window.
"Sleep()" is a function I have explained before. Basically, it pauses the output in the console.
"endl;" ends the line. This pretty much simulates pressing the "enter" button in the console output.
Any text between quotation marks are strings.
"else" is what executes if the user types anything other than 1 (more options will be added soon).
"char" is a character.
"||" is an or operator.
Hopefully I've explained everything that may be foreign to someone who doesn't know C++. If you use the above as a guide, you should be able to piece together at least a basic understanding of what is happening. Trust me, none of this is advanced so anyone with at least a little bit of knowledge in C++ won't even need the above information. If you have any trouble understanding what is happening, I recommending reading a basic C++ tutorial online.
