Question 4
Given the class Qz4:
class Qz4 {enum{ arr_l=5 };int *arr; // array of intint seed;char *name;public:Qz4(char *str, int i) : name(str), seed(i) {arr = new int[arr_l];for(int i=0;i<arr_l;arr[i]=seed + i++);}~Qz4() {delete [] arr;cout << "arr destroyed for " << name << endl;}void print_arr() {cout << name << ":" << endl;for(int i=0;i<arr_l;i++) cout << "Element #" << i << "=" << get_arr(i) << endl;}void set_arr(int idx, int val) {arr[idx]=val;}int get_arr(int idx) {return arr[idx];}};
Can you predict the output of the program below?
int main() {Qz4 q1("Q1",0), q2("Q2",10);q2=q1;q1.set_arr(0, 32);q2.set_arr(1, 56);q1.print_arr();q2.print_arr();}
