Question
Transcribed Image Text:Here is part of the code from the main function in a program:
```cpp
int n1, n2, n3 = 8;
double answer;
string name = "Homer", city;
```
Assume function `doSomething` has a string parameter and that it returns an int. Which of these would be valid ways to call the function from `main`? Please check all that apply. Wrong answers subtract points.
- [ ] `city = doSomething(name);`
- [ ] `answer = sqrt(doSomething("Bob"));`
- [ ] `n2 = doSomething("Adele is great!");`
- [ ] `cout << doSomething(n1) << endl;`
- [ ] `cout << doSomething(name) << endl;`
- [ ] `n1 = doSomething(name);`
