Here is a small program. Which of the statements about this code is correct?
```
#include
const double NUM = 2.9345358;
double num = 3;
double numTimes(int x);
int main( )
{
using namespace std;
int value;
cout << “Enter a value, I’ll multiply it by “
<< NUM << endl;
cin >> value;
cout << “You entered “ << value
<< “ NUM times this is “ << numTimes(value)
<< endl;
return 0;
}
double numTimes(int x)
{
double d;
d = NUM * x;
return d;
}
```
a) The variable x is a parameter in function numTimes
b) The variable value is an argument in a call to numTimes.
c) The line double numTimes(int x); is a function definition.
d) The line return d; in the function numTimes is necessary.
e) The lines of code are a function declaration:
```
double numTimes(int x)
{ . . .}
```
a) The variable x is a parameter in function numTimes, b) The variable value is an argument in a call to numTimes., and d) The line return d; in the function numTimes is necessary.
c) is a function declaration or prototype not a definition. e) is a definition. It is also a declaration, as definitions are also declarations, but the lines of code do not constitute a declaration.
