Wouldn't it be more efficient to write
while(num<5){
cout << "The number is" << num << endl;
num = num + 1;
}
as
while(num<5){
cout << "The number is" << num++ << endl;
}

#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?
