Decision-making in programming is similar to real-life choices, where actions depend on
conditions.
Programs execute specific statements based on true or false outcomes, ensuring structured
and logical flow.
CONDITIONAL STATEMENTS
Decision making in BASIC-256 is done by conditional statements or decision-making statements
which decide the direction of the flow of program execution. Since they control the execution of
the program, you also call them Control statements. Control statements available in BASIC-256
are given below.
IF-THEN Statement
IF-THEN-ELSE Statement
IF-THEN Statement
The IF-THEN statement is the simplest conditional statement. Here, certain statement or block
of statements within the if block is executed only if specified condition evaluates to true. If the
condition evaluates to false, then the control of execution is passed to the last statement, outside
the if block.
The syntax of the IF-THEN statement is given below.
