What is a statement in coding?
In computer programming, a statement is a syntactic unit of an imperative programming language that expresses some action to be carried out. A program written in such a language is formed by a sequence of one or more statements. A statement may have internal components (e.g., expressions).
What are logical control structures?
Control structures determine the flow of a program. … There are selection type controls that make use of comparison and/or logical operators to select a course of action for the program, and there are loop type structures that repeat a set of instructions until some condition is met.
What is the syntax of if else statement?
Syntax. If the Boolean expression evaluates to true, then the if block will be executed, otherwise, the else block will be executed. C programming language assumes any non-zero and non-null values as true, and if it is either zero or null, then it is assumed as false value.

What are the 3 types of control structures?
Flow of control through any given function is implemented with three basic types of control structures:Sequential: default mode. … Selection: used for decisions, branching — choosing between 2 or more alternative paths. … Repetition: used for looping, i.e. repeating a piece of code multiple times in a row.
What is if not in Python?
