A program is an application or an equivalent interface whereas a process is the underlying function or functions of a program
Typically, all functions in any program constitute a single process. Multiple processes can communicate via Interprocess Communication (IPC), but are usually regarded as separate programs.
Commands provide access to a program's functions.
A process in which a program is developed. wordd.
There is no limit to the number of functions you can have in a program. The only practical limit is dependant upon the amount of memory you have available in order to load the compiled program, whether it has 4 functions or 4 trillion functions. If the program makes use of dynamic libraries, then the amount of available memory reduces accordingly.
In order to make a large program more manageable, it is convenient to identify and isolate specific tasks that a program performs and to separate out those tasks into functions. These functions are used/invoked as needed by the main part of the program. They can also be invoked by other functions. Often a program will perform the same task in different parts of the program. Using a function to perform the task and invoking the function from the different parts of the program means that only one copy of the code is needed. This helps reduce the size of the program.
Functions are very important in C++, as you can't write the simplest program to print hello without using a function. Overall you can say that function are building blocks of a C++ program. Functions can also be defined by the programmer to reduce program size.
Program is a set of instruction whereas process is program in execution. Program is passive entity whereas process is active entity .Program has single instance whereas process has several instances.For eg.several notepad windows can be opened but same program is executed behind each window. Program is dependent on logic used whereas process is dependent on program.
C programs do not function without functions.
When you tell your computer to run a program, a new process is created which runs the code in that program. A process is an instance of a program.
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
Programming someone requires inserting a chip into their brain, and soldering it up to their nervous system.
