Explanation:
namespaces can be nested. That is we can have a hierarchy of namespaces.
For examples suppose we have a namespace top. Within this we have another namespace first. At the next level we have a namespace called second. Then we have a class MyClass as a member of this namespace second. Then the complete description of the class will be as follows:
top::first::second::MyClass
Answer:
if ((b*b - 4*a*c)<0)
cout << "no real solutions";
return;
Explanation:
To check if "b squared" – 4ac is negative, we use the expression if ((b*b - 4*a*c)<0). This expression evaluates the 'bsquared' and substracts '4ac' from it. It then compares the resulting value with zero. if it is less than zero it means it is a negative number, so it executes the statement following cout << "no real solutions"; and returns

Answer:
public static double average(int num1, int num2){
return (num1+num2)/2;
}
public static double average(int num1, int num2, int num3, int num4){
return (num1+num2+num3+num4)/2;
}
Explanation:
- In the first instance, the method average() accepts two parameters and returns their average
- In the second instance the method accepts four parameters and returns their average
- The concept of method overloading allows a program to have more than method with the the same name but with different parameters list like we find in this example
