Let us develop a simple program
where the cat sprite moves
towards a basketball when the
right arrow key is pressed. The
code for the cat sprite can be
similar to this. Sensing block
STORING USER INPUT
The program can also be developed to take input from the
user. Earlier, we developed a program to divide 12 by 5.
Scratch gives an option to take input from the user also. To
develop a program to divide two numbers and find the
quotient, define the script of the sprite as:
When the program is run, a small text input box opens at the
bottom of the stage. Type the value of the variable and press
the Enter key or click on the tick mark symbol on the right
side of the text box. The final output of the program will be
similar to this.
