Basics Downloading and installing CodeBlock Creating and explaining first project Hello World – the terms (keyword, main, header file) Keyword – Keywords are reserved words for compiler whose purpose is already defined in compiler and user cannot use for personal use. E.g if, else, double, switch main – main is a necessary function to define to execute C/C++ program. Without main, we cannot run our program. Header file  - header file contains functions that perform certain tasks  Characters \n, \t, \a data types: int – 4b, float – 4b, double – 8b, char – 1b, string – equal to the number of characters variable: rules to define a variable cannot start with numbers and special characters. Only special character acceptable is _ e.g. _age Camel case: weightInKg Snake Case: weight_in_kg declaration vs initialization arithmetic operations (+, -, *, /, %) input from user – cin, getline() relational operators (>=, <=, >, <, ==, !=) if selection statement if…else – double s...
