Control Statements: For Loop, If, Else
To use simple yet useful control statements: for loop and if and else.

Let’s just say you need to check through a column vector of data values to see if it meets a certain condition or only executes a function if it means a certain condition. In this example, we need control statements that allow us to control the flow of a program.
There are quite a few control statements you can learn in programming, but the most useful and simplest control statements are the “for loop” statement, the “if” and “else” statements.
