The input statement
Syntax:
input( variable[, variable, …] )
E.g.:
input(a)
input(a, b)

The output statement
Syntax:
output(string/ variable[, string/variable, …] )
E.g.:
output(a)
output(a, b)
output(“Hello guys..”)
output(“The value of X is “, x)

Exercises
Create an algorithm that asks two integers and display them back on screen.
Create an algorithm that asks three integers, multiplies them, and displays the result on screen.

Exercises
Create a algorithm that asks one integer (seconds) and converts it into hours, minutes, and seconds form. Display the result on screen.
Create a algorithm that calculates and shows the area of a circle. The algorithm gets radius of the circle in floating-point number.

Exercises
Create an algorithm that asks for two coordinates ({x1, y1} and {x2, y2}) in integer. Display the linear equation that through the coordinates in y=mx+c form.
E.g.:
The linear equation that through {1, 2} and
{5, 7} is y=1.25x + 0.75.

Exercises
The quadratic equation is shown by:
a 2 + bx + c = 0
This equation has two roots.
Create an algorithm that receives three inputs, such as a, b, and c. Then the algorithm prints two roots of the equation to the screen.
