int main(){int age[5] ={10};

cout << “Array elements before passing array to function” << endl

for (int i =0; i <5; i++)

cout << “Array element"<< i+1 << <<age[i] [ << endl

updateAge(age); A

cout << "Array elements after passing array to function" << endl

for (int i =0; i <5; i++)

cout << “Array eIement"<< i+1 << <<age[i] [ << endl

void updateAge(int age[], int size){ age[3] = 20
