Q.1 What is the role of parameter passing in subprogram invocations ? Consider following code :

Void swap (int a, int b){
    int temp = a;
    a = b;
    b = temp;
}
void main(){
    int list[5] = {1,3,5,6,10};
    value = 15;
    swap (value,list[0]);
    swap (list[0],list[2]);
    swap (value,list[3]);
}

Consider different methods of parameter passing find the values of variable value and list after each call of swap function.

Q.2 Differentiate between static and dynamic storage management approaches.
