Answer:
When myMethod is invoked by a method in the same class as myMethod.
Explanation:
When you are in a class, it is like a different enviroment and within that class you can call a method without using the dot notation because you are still within the class.
Outside the class and despite the type of method, public, private or static, the dot notation will be required.
Answer:
Following are the program to this question:
#include <iostream>//defining header file
using namespace std;
int recurs(int x, int n)//defining a method recurs that accepts two parameter
{
if(n==0)//defining if block that checks n value
{
return 1;//return value 1
}
else//defining else block
{
return x*recurs(x,n-1);//use return keyword that retun value
}
}
int main()//defining main method
{
cout<<recurs(5,3); //use print method to call recurs method
return 0;
}
Output:
125
Explanation:
In the above-given program, the integer method "recurs" is declared which accepts, two integer variables, which are "x, n", inside the method the if conditional statement is used.
- In the if block, it checks the value of n is equal to "0" if this condition is true, it will return a value, that is 1.
- Otherwise, it will go to the else block, in this block, it will use the recursive method to print its value.
