CS – 415 Homework 1: Due: In class, 3/21/23

data[1..10] : integer;

x, y: integer;

procedure f1(pet : array[1..10] of integer)

procedure f11(s : integer)

begin

pet[x] = 12; data[s] = 24;

end

procedure f12(x : integer)

begin

f11(y+x)

end

begin

x = x + y; f12(y);

output pet array; output data array

end

procedure f2(temp : array [1..10] of integer)

procedure f21(p : integer)

begin

x = 2; p = x * p;

end

procedure f22(q : integer)

begin

q = 7;

end

begin

x = 5; f22(x);

temp[x] = x; f21(temp[x]);

output temp array output data array

end

begin

x, y, and all elements of the data array are initialized to 1.

Call f2(data);

Output data array

Call f1(data);

Output data array

end
