How do we arrive at 26 as answer here?
int a = 10;
int b = 13;
int *p1= &a;
int *p2= &a;
*p1 = b;
cout << (*p1) + (*p2);

#include <iostream>
using namespace std;
int sum(int a, int b=42) {
int result = a + b;
return (result);
}
int main() {
int x = 24;
int y = 36;
//calling the function with both parameters
int result = sum(x, y);
cout << result << endl;
//calling the function without b
result = sum(x);
cout << result << endl;
return 0;
}
why is da last function cout 66 and not 48 isn't it suppose to add 24+24?
