Let us write some algorithm based on selection control structure.
Algorithm 6: Write an algorithm to input two numbers and display the larger one.
Step 1: Start
Step 2: Input NUM1 and NUM2.
Step 3: If NUM1 > NUM2 then
Display NUM1 is greater than NUM2.
Else
Display NUM2 is greater than NUM1.
Step 4: Stop
Algorithm 7: Write an algorithm to input a number and check whether it is positive, negative,
or zero.
Step 1: Start
Step 2: Input NUM.
Step 3: If NUM > 0 then
Display NUM, is a positive number.
Else if NUM < 0 then
Display NUM, is a negative number.
Else
Display NUM, is 0.
Step 4: Stop
Algorithm 8: Write an algorithm to input three numbers and display the smallest one.
Step 1: Start
Step 2: Input NUM1, NUM2, and NUM3.
Step 3: If NUM1 < NUM2 and NUM1 < NUM3 then
Display smallest number: NUM1.
Else if NUM2< NUM1 and NUM2 < NUM3 then
Display smallest number: NUM2.
Else
Display smallest number: NUM3.
Step 4: Stop
Algorithm 9: Write an algorithm to input a number and check whether it is even or odd.
Step 1: Start
Step 2: Input NUM
