Getting started

Hello, Qu

hello, world, and a bit of arithmetic.

catalog/demo_hello.qu

The first program to run in Qu. Prints a greeting, does some ordinary arithmetic, and shows string interpolation with a format spec.

What it exercises

• print(), string interpolation, +/-/*// and ^, variables

How it works

print("Hello, Qu!")

a = 6
b = 7
print("a + b = {a + b}")
print("a * b = {a * b}")
print("b ^ 2 = {b ^ 2}")
print("pi    = {pi:.4f}")

Results

Hello, Qu!
a + b = 13
a * b = 42
b ^ 2 = 49
pi    = 3.1416
