Can Sololearn's compiler be incorrect?

Question

I've created an simple arithmetic program and it keeps on giving the wrong output even though nothing is wrong with the code.

Answer 1

I can see you're not initializing "totalage", for one. If you don't initialize a variable, you're just going to get junk memory.

You want:

int totalage = 0;

Answer 2

You may post your code for inspection.

Answer 3

Please provide sample input, expected output and actual output

Answer 4

If you are talking about your "basic calculator (0-9)" code, you are using the "if" incorrectly. Replace
if (num1, num2, num3 >= 10) with
if (num1 >=10 && num2 >= 10 && num3 >= 10) and it will work.

Answer 5

You can try it with other compilers.

Answer 6

Actually, that works fine. This is the code. . .

Answer 7

#include <iostream>
using namespace std;

int main() {
int age;
int totalage;
int numofpers = 0;

cout << "Enter first person\'s age: " << endl;

cin >> age;

while (age != -1) {
totalage += age;
numofpers++;

cout << "Enter next person's name or enter -1 to cancel." << endl;
cin >> age;
}

cout << "Your total age is " << totalage << endl;

cout << "Your average age is " << totalage/numofpers << endl;

}
