How to write an effective program using c plus plus?

Answer 1

Here is a simple program that will tell you how to make an algorithm:

int main();

{

int length;

int width;

int total;

printf("What is the width: ");

scanf("%d", &width);

printf("What is the length: ");

scanf("%d", &length);

total = width * 2 + 2 * length; /*Here is the algorithm for finding the perimeter of a square*/

printf("The perimeter is: %d", total);

return 0;

}

Output:

What is the width: 32

What is the length: 55

The perimeter is: 174

Answer 2

Function-header, consisting of return type, name of function, parameter.

Function-body, consisting of statements enclosed in curly braces {}.

Simple example:

#include /*Function-call*/

void main(void) /*Function-header*/

{

printf("Hello world!"); /*Function-body and statements start here*/

}

Answer 3

C Programming language is already defined, you don't have to do anything with it.

You could write a C-compiler, if your were much more experienced than you are now.

Or you can write a program in C, I give you an example:

#include

int main (void)

{ puts ("Hello, world!"); return 0; }

Answer 4

An algorithm is simply a description of the logical step-by-step procedure required to solve a particular problem. You do not write algorithms in C (or indeed in any programming language) you write them in your native language (such as English). Algorithms that employ loops or conditional expressions are typically presented using a flowchart to better visualise the implementation of complex algorithms, however all complex problems can be broken down into a sequence of much simpler problems each of which has its own algorithm. When presenting algorithms to programmers from various backgrounds, pseudo-code is used to provide a language-agnostic version of the implementation that can easily be translated into any language but, ultimately, it is the programmer's responsibility to translate algorithms into functional code. But first you have to write the algorithm. Ignore the language and concentrate on the problem itself. Describe how the problem should be solved, then write the code to implement your solution.

Answer 5

No-one can answer a question like that here!

For a start you've not told us what you want the programme to do: complex word-processing, heavy mathematics, process-control, high-speed graphics...?

The most anyone could do here is answer specific queries about particular commands, routines or errors that have baffled you.

Even introductory books on C++, or any other language, are hefty tomes.

You can only learn effective computer programming on a formal course, unless your aptitude and previous experience is sufficient to allow you to pick it up from a text-book, worked examples and a heck of a lot of practice.

Answer 6

You can write a C++ program using nothing more than notepad, however a C++ editor is easier to work with. However, to execute the program, you will also need a C++ compiler and linker. A C++ integrated development environment (IDE) will provide all the tools you need to get started.

Answer 7

You will need to first know a C language such as C# or C++. You will then need a compiler that takes what you write and turns it into a running program.

Answer 8

Pseudo-code an C-source are different things, don't try to mix them.

Answer 9

Its not a single line question.
