    Just for an idea i will explain something:

    Topdown Approach
    Execution starts from top of the program to the end...
    Eg: C program
    Code:
    #include<stdio.h>
    void test();
     void main() 
          {
           test();
          }
    void test()
    {
    printf("Test program");
    }
     In this program, Execution starts from top of the main function to the bottom ofthe test function.
    
    Eg: Bottom -to -top approach(C++ program)
    
    #include <iostream>
    using namespace std;
    class sample
    {
    public:
           void test()
               {
              cout<<"Sample";
              }
    };
    
    void main()
            {
            Sample s;
            s.test();
            } 
    In this program,Execution starts from the bottom of the main function to the test function present in a class.
