When you write the routine for functions and sub programs and go for the main function, it is called the bottom up approach. If you do the process in reverse it is called the top down approach..
Top-down, Bottom up Approach
It is a programming language. s of course its a programming language with bottom up approach for programming. because it follows oops concepts
Top down and bottom up programming are two approaches or methodologies employed for designing structured programs in C.TOP DOWN APPROACHIn a top down approach a program(structured) is designed by using the top down methodology as follows..First the overall structure of the program is designed and it is defined and then it is followed by the designing of individual functions..BOTTOM DOWN APPROACHThe bottom down approach is just the opposite of the top down approach..ie, the program is designed by first designing the individual functions followed designing of overall program structure
Most programmers would agree that a bottom-up approach is best.
top-down and bottom-up processing
top down/bottom up approach, plan, prepare, execute, assess
bottom-up
Top down approach is based on Chip level flow, If the design is small then we can opt for this approach . Bottom down approach is hierarchical based chip design flow, If our Design is big, then , the chip is divided in to small manageable modules, it is similar to "Divide and Conquer approach", Finish the small manageable modules , so that the run time will be controlled, and then finally integrate in to one-chip.
buttom up is first create class, generate methods and create a wsdl from this, top down is first create wsdl and than generate codes depend on this wsdl
bottom-up
Is open-source development a top-down or bottom up methodology
