I don't understand why I can't make a sum of two functions that returns an int value. For example:
def N1():
x=3
return x
def N2():
y=4
return y
print (N1+N2)

#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?

In the code below the output is 2. This code is used in a challenge and I get an error when I select the answer 2. It accepts as correct the answer 1 which I believe is wrong. If you agree please thumbs up.
If you find any other errors please post them here!
#include <iostream>
using namespace std;
int main()
{
for(int i=1; i>=1; i++) {
if(i<1 || i>1){
cout << i;
break;
}
}
return 0;
}

Define a Python function "orangecap(d)" that reads a dictionaryd of this form and identifies the player with the highest total score. Your function should return a pair(playername,topscore) whereplayername is a string, the name of the player with the highest score, andtopscore is an integer, the total score of playername.
