An Algol-60 example of passing parameters by name. Later versions of the language switched to passing parameters by value. The syntax is not guaranteed to be correct - it's hard to come across an Algol-60 compiler these days...
begin
integer array A[1:3];
integer i;
integer procedure what(n);
integer n;
begin
for i:= 1 step 1 until 3 do n := i
end;
what(A[i])
end
Question 1: What is the result of the following code?
Question 2: Write a similar procedure to compute the sum of all
elements in an array.
