What’s wrong with the following code? (Hint: try to replace ap += SIZEOF_LOCALS with alloc_locals and see what happens) Can you fix it without changing the order of the variable definitions in the code?
func main():
tempvar x = 0
local y
ap += SIZEOF_LOCALS
y = 6
ret
end
Rewrite the solution to Exercise – A simple Cairo program using temporary variables.
func main():
[ap] = 100; ap++
[ap] = [ap - 1] * [ap - 1]; ap++ # x * x (x^2)
[ap] = [ap - 1] * [ap - 2]; ap++ # x^2 * x (x^3)
[ap] = [ap - 2] * 23; ap++ # x^2 * 23
[ap] = [ap - 4] * 45; ap++ # x * 45
[ap] = [ap - 3] + [ap - 2]; ap++ # x^3 + x^2 * 23
[ap] = [ap - 1] + [ap - 2]; ap++ # x^3 + x^2 * 23 + x * 45
[ap] = [ap - 1] + 67; ap++ # x^3 + x^2 * 23 + x * 45 + 67
ret
end
