1. Programming for Problem Solving

2. What is Computer Program? A computer program is a collection of instructions that can be executed by a computer to perform a specific task.

3. What is Computer Programming? Computer programming is the process of designing and building an executable computer program to accomplish a specific computing result or to perform a specific task.

4. Program and Programming A computer program is usually written by a computer programmer in a programming language. From the program in its human-readable form of source code , a compiler can derive machine code — a form consisting of instructions that the computer can directly execute. Alternatively, a computer program may be executed with the aid of an interpreter .

5. SOURCE CODE/HIGH LEVEl LANguage : Understable by human beings MACHINE CODE(Binary code) 0 and 1 /LOW LEVEL LANGUAGE: Understandable by computer

6. Compiler The name "compiler" is primarily used for programs that translate source code from a high-level programming language to a lower level language (e.g., machine code) to create an executable program.

7. Interpreter Interpreter is a program that executes instructions written in a high-level language.

8. Compiler vs Interpreter Interpreter  translates just one statement of the program at a time into machine code.  Compiler  scans the entire program  and  translates the whole of it into machine code at once. 

9. Programming Cycle in C++ Think about what program is supposed to do. Edit Program (comment program and then write code) Save Program Compile Program Fix Syntax Errors (Go back to Think above) Run/Test Program Fix Logic Errors (Go back to Think above) Run Program
