1. Introduction

Algorithms are Step-by-step procedures to solve a problem.

This section covers some key aspects of algorithms, including control structures and their pseudocode.

1.1. Control structures

Control flow is the execution order of instructions or functions in a program.

Flow of control is implemented via control structures:

• sequence, which executes line by line in written order

• selection, which chooses between alternatives

• iteration, where looping determines how many times the instruction is executed.
