Question

Which of the following must be true if there is a variable of the same name and type in main as in a function’s parameter list? For example,
double area(double radius)
{
    return ( M_PI*radius*radius );
}

int main()
{
    double radius = 3;
    double a = 5;
    cout << "Area: " << area(a);

    return 0;
}

a. The value of the variable in the function area() will be the same as the value of the variable in main().

b. The variable in the parameter list must be a reference parameter.

c. The variable in the parameter list must be a constant.

d. This is a syntax error.

e. These are two separate data storage locations and except for having the same name are unrelated.
