Write the output of the following statements:

1. if (today is Sunday) then 2. if (a>90) then
print "Weekend" print "Excellent"
else else
print "No weekend" print "Try harder"

Assume that today is Sunday Assume that the value of a is 85.

Once you understand how conditions work, you can guess the output based on different inputs. This
is called logical reasoning.

For example,

if marks ≥ 40 then

print "Pass"

else
print "Fail"
Try these inputs:

Marks = 75 Æ Output: Pass

Marks = 28 Æ Output: Fail

Marks = 40 Æ Output: Pass
By checking the condition, you can predict the correct output.

Timeline

A loop allows a set of instructions or a block of code to be executed repeatedly.

Loops are classified on the basis of how many times they repeat — one is finite and the other is
infinite.
A finite loop is a type of loop that repeats a set of instructions for a fixed number of times.
An infinite loop, on the other hand, keeps repeating the instructions forever unless it is manually
stopped or interrupted by a condition.
An algorithm is a list of clear and step-by-step instructions to solve a problem or complete a task.
The if statement is the simplest conditional statement.
