Challenges I

Variable assignment 1

Use = to assign the value 123 + 456 to a variable named x.

Then print x.

Multi-line hello world

Make your program output "hello" on one line, and "world" on the next line.

In other words, your program must output:

hello
world

Variable assignment 2

Use = to assign the string "some string" to a variable named something that you choose. (But don't use x.) Then print the variable.

Exploration

What happens if you multiply a string with a number? What do you think would make sense?

Find out by multiplying "test" by 3 using the * sign and printing the result.

Two assignments

Use = to assign the string "lesson" to a variable named something that you choose.

Then use = to assign the number 5 to another variable.

Then print the first variable.

Then print the second variable.

Area of a rectangle

Write a program that stores 45 in a variable named width and that stores 81 in a variable named height.

Then multiply the two variables, storing the result in a variable named `area'.

Finally, print the calculated area.

Adding to variables

Store the value 999 in a variable named number.

Then, on a new line, store number + 1 into the number variable, like this:

number = number + 1

This has the result of adding 1 to the number variable.

Then print number.

Imperial to metric

Store the number 6 in a variable named feet.

Then store the number 3 in a variable named inches.

Then store 30*feet + 3*inches in a variable named cm.

Finally, print cm to see how many centimeters 6 feet and 3 inches are.

Years to hours

Bob just turned 35 years old.

Calculate and print how many hours Bob has lived.

You should assume that there are always 365 days in a year, and 24 hours in a day. (So ignore leap years.)

You can use variables to store the results of your calculations, or you can do the whole thing in one line.
