Computers never do what you want them to do. They only do what you tell them to do
Definitions
1. Algorithms - its a way to solve a problem with a finite of steps.
2. Pseudocode - a program code unrelated to the hardware of a particular computer and requiring conversion to the code used by the computer before the program can be used.
3. Machine Language - a system of instructions and data excecuted by a computer's centeral processing system.
High level computer language- In computing, a high-level programming language is a programming language with strong abstraction from the details of the computer.
A high level language isolates the execution semantics of a computer architecture from the specification of the program, making the process of developing a program simpler and more understandable with respect to a low-level language. The amount of abstraction provided defines how 'high level' a programming language is.
Flowchart- a logic to solve problems.
