Input & Output

Output

print('no newline')
println('with newline')
println(42)
println('x = ' .. x)

print and println take exactly one argument, any expression. Floats print with up to six significant digits.

Input

Input functions return the value read:

age = inputInt()
name = inputStr()

• inputInt() reads a whitespace-delimited token and converts it to an integer. If it is not a valid integer it prints Invalid value! and returns 0.
• inputStr() reads one whitespace-delimited word. It cannot read a line containing spaces.

Both read from standard input, so the prompt has to be printed first:

print('Enter your birth year: ')
year = inputInt()
