Learn C++ by Creating

Today you will create the quintessential first program. It is customary, when learning a new programming language, to start with Hello World! This program is the bare minimum of what a c++ program can be. It will output “Hello World!” and that is it.

PROJECT DESCRIPTION

Today you will create the quintessential first program. It is customary, when learning a new programming language, to start with Hello World! This program is the bare minimum of what a c++ program can be. It will output “Hello World!” and that is it.

PROGRAMMING CONCEPTS

• int main(){ }
• <iostream>
• std::cout <<
• \n
• std::cin.ignore();
• return 0;

PROJECT DESCRIPTION

Learning C++ programming can be very intimidating, but we will be working on building our skills one level at a time. This time we will be adding some user interaction to the Hello World application from Level 1.

PROGRAMMING CONCEPTS

• <string>
• std::string name;
• getline (std::cin, name);

PROJECT DESCRIPTION

This level offers a small glimpse of what you can do with strings. We are going to use Nice to Meet You to play with some of the included features in the string library.

PROGRAMMING CONCEPTS

• string.length()
• string.front()
• string.back()
• string.append(“string”)
• std::cout <<a<<b<<c;

PROJECT DESCRIPTION

Alan Turing was mathematician who proposed a test in 1950 known as the Turing Test. A computer program would be considered intelligent if it could convince a human, through a text conversation, that it was human. For this level we will build upon Level 2 to try to have a conversation.

PROGRAMMING CONCEPTS

• Variable Declarations
• Writing One Line on Multiple Lines

PROJECT DESCRIPTION

So far we have built programs using strings, but lets look at a new data types. We are going to create a little basic calculator. Plus, we are going to use a namespace to make writing our code simpler.

PROGRAMMING CONCEPTS

• int
• using namespace std;
• endl
• cin >>
• Integer Arithmetic
• Modulo

PROJECT DESCRIPTION

Computers do not treat all numbers the same. It sees integers and decimals differently and we are going to explore that by modifying our Integer Calculator to handle decimals. That means that we will be using a the data type double for the first time.

PROGRAMMING CONCEPTS

• <iomanip>
• double number1;
• cout << setprecision(3) << fixed;
• double/doubl

PROJECT DESCRIPTION

Computers do not treat all numbers the same. It sees integers and decimals differently and we are going to explore that by modifying our Integer Calculator to handle decimals. That means that we will be using a the data type double for the first time.

PROGRAMMING CONCEPTS

• if(){}
• number = 4;
• number1==number2

PROJECT DESCRIPTION

This level continues where we left off at the end of Level 7. Our last program did not output anything if we got the answer wrong. In this level we will be adding that missing component.

PROGRAMMING CONCEPTS

• else{}
• //Comments
• camelCase

PROJECT DESCRIPTION

This level continues where we left off at the end of Level 7. Our last program did not output anything if we got the answer wrong. In this level we will be adding that missing component.

PROGRAMMING CONCEPTS

• <, >
• if-else if-else
• else if ( ){ }
