Run Code

1. Write a program that adds 1 plus 1 together and outputs the answer


2. Input a number from the user, then return the number inputted from the user multiplyed by 10.


3. Input a number from the user, then return the number inputted from the user multiplyed by itself. For example, if the user inputs 5, your program would return 25.


4. Create a program that inputs my postcode as a string. Create a variable NEIGHBOUR and use it to store (using the int function) the inputted postcode minus one. Output "The postcode in the next suburb is NEIGHBOUR" (where NEIGHBOUR is the value of the neighbouring postcode.)



Extension:



5. Write a program that calculates the area of a circle from a given radius input


6. Ask a user to input their age. Print out their year of birth by using the formula year of birth = current year - age (in years)


7. Write a program that inputs two whole numbers into two variables (call the variables num1 and num2), then outputs the sum, product and difference of those two numbers.


8. Write a program that inputs a whole number, and prints an arrow like this: ---> but with the length of the arrow (or number of dashes in the arrow) equal to the whole number inputted
