The following program fragment is written in a programming language that allows global variables and does not allow nested declarations of functions. global int i=100, j=5; void P(x) { int i=10; print(x+10); i=200; j=20; print (x); } main() {P(i+j);} If the ... and call by need parameter passing mechanism, the values printed by the above program are: $115, 220$ $25, 220$ $25, 15$ $115, 105$

Consider the following pseudo-code (all data items are of type integer): procedure P(a, b, c); a := 2; c := a + b; end {P} begin x := 1; y := 5; z := 100; P(x, x*y, z); Write ('x = ', x, 'z = ', z); end Determine its output, if the parameters are passed to the Procedure P by value reference name

What is the return value of $f(p,p)$, if the value of $p$ is initialized to $5$ before the call? Note that the first parameter is passed by reference, whereas the second parameter is passed by value. int f (int &x, int c) { c = c - 1; if (c==0) return 1; x = x + 1; return f(x,c) * x; }
