What is a selection in programming?

Home / Programming / Selection In Programming. A selection is used to make choices depending on information. An algorithm can be made smarter by using IF, THEN, and ELSE functions to reiterate instructions, or to move the process in question to different parts of the program. Selection is also called a decision.

Why do we use selection in programming?

Why is selection important? Selection allows there to be more than one path through a program. Many solutions feature several choices or decisions. … Without selection it would not be possible to include different paths in programs, and the solutions we create would not be realistic.

What is sequencing in coding?

In programming, sequence is a basic algorithm: A set of logical steps carried out in order. Computers need instructions in the form of an algorithm in order to complete a desired task, and this algorithm must have the correct order of steps, or sequence. Example: We can relate sequence to our everyday lives.

What is selection and iteration in programming?

Iteration is when we use loops to repeat code in a program. Selection is when we use conditionals (if/else) to execute different blocks of code in a program.

What is selection in C++?

Selection Statements (C++) The C++ selection statements, if and switch, provide a means to conditionally execute sections of code. The __if_exists and __if_not_exists statements allow you to conditionally include code depending on the existence of a symbol. See the individual topics for the syntax for each statement.
