Conditions in a Program
While writing a program, we need to make certain decisions based on the logic of the program.
Such situations are called conditions. Conditional statements are used in a program to instruct the
computer to make a decision. The result of the computer’s decision for a condition will always be
either a true or a false.
if-then-else
The program executes the statements written after ‘if’ when the condition is true. If it is false, the
statements written after ‘else’ will be executed.
Yes If (Condition) No
to be checked
Then Else
