Jun 28, 2009 Hi. I'm using dev C and want to make a windows app instead of making console programs all the time. The problem is when i go file new and select windows app it loads up a page with pre written code and i dont know where to put my code in or how to modify the program. Dec 11, 2013 made with ezvid, free download at To compile a c program by dev c. Mar 18, 2020 C is a general-purpose object-oriented programming language. It was created by Bjarne Stroustrup at Bell Labs circa 1980. C is very similar to C (invented by Dennis Ritchie in the early 1970s). C is so much compatible with C that it will probably compile over 99% of C programs without changing a line of source code. Jun 22, 2016 C – Program to Make Simple calculator in C June 22, 2016 admin C 2 Write a program and call it calc.cpp which is the basic calculator and receives three values from input via. 2) Object oriented – C supports object oriented programming features, which means we can use the popular OOPs concepts such as Abstraction, Inheritance, Encapsulation and Inheritance in C programs, these features make writing code in C a lot easier. We will cover them in detail in this tutorial series.

Example 4 - while loop example
#include <stdio.h>
int main()
{
int c =1;// Initializing variable
while(c <=10)// While loop will execute till the condition is true
{
printf('%d ', c);// Note the space after %d for gap in the numbers we want in output
c++;
}
return0;
}
int main()
{
int c =1;// Initializing variable
while(c <=10)// While loop will execute till the condition is true
{
printf('%d ', c);// Note the space after %d for gap in the numbers we want in output
c++;
}
return0;
}
Output:
1 2 3 4 5 6 7 8 9 10
1 2 3 4 5 6 7 8 9 10
Example 5 - C program check if an integer is prime or not
#include <stdio.h>
int main()
{
int n, c;
printf('Enter a numbern');
scanf('%d',&n);
if(n 2)
printf('Prime number.n');
else
{
for(c =2; c <= n -1; c++)
{
if(n % c 0)
break;
}
if(c != n)
printf('Not prime.n');
else
printf('Prime number.n');
}
return0;
}
int main()
{
int n, c;
printf('Enter a numbern');
scanf('%d',&n);
if(n 2)
printf('Prime number.n');
else

}
Example 6 - command line arguments
#include <stdio.h>int main(int argc,char*argv[])
{
int c;
{
int c;
printf('Number of command line arguments passed: %dn', argc);
for(c =0; c < argc; c++)
printf('%d argument is %sn', c +1, argv[c]);
printf('%d argument is %sn', c +1, argv[c]);
return0;
}
}
This program prints the number of arguments and their contents.

}
// Defining the function
void my_function()
{
printf('Welcome to my function. Feel at home.n');
}
void my_function()
{
printf('Welcome to my function. Feel at home.n');
}
Example 9 - Using comments in a program
#include <stdio.h>
int main()
{
// Single line comment in a C program
printf('Writing comments is very useful.n');
/*

* Comments help us to understand a program later easily.
* Will you write comments while writing programs?
*/
printf('Good luck C programmer.n');
return0;
}
int main()
{
// Single line comment in a C program
printf('Writing comments is very useful.n');
/*
* Multi-line comment syntax
* Comments help us to understand a program later easily.
* Will you write comments while writing programs?
*/
printf('Good luck C programmer.n');
return0;
}
Example 10 - using structures in C programming
#include <stdio.h>#include <string.h>
struct game
{
char game_name[50];
int number_of_players;
};// Note the semicolon

#include <graphics.h>#include <conio.h>
int main()
{
int gd = DETECT, gm;
initgraph(&gd,&gm,'C:TCBGI');
outtextxy(10,20,'Graphics programming is fun!');
circle(200,200,50);
setcolor(BLUE);
line(350,250,450,50);
getch();
closegraph();
return0;
}
{
int gd = DETECT, gm;
initgraph(&gd,&gm,'C:TCBGI');
outtextxy(10,20,'Graphics programming is fun!');
circle(200,200,50);
setcolor(BLUE);
line(350,250,450,50);
getch();
closegraph();
return0;
}
How to compile C programs with GCC compiler?
If you are using GCC on Linux operating system, then you may need to modify the programs. For example, consider the following program that prints the first ten natural numbers.
#include <stdio.h>#include <conio.h>
int main()
{
int c;
{
int c;
for(c =1; c <=10; c++)
printf('%dn', c);
getch();
return0;
}
printf('%dn', c);
getch();
return0;
}
The program includes a header file
#include <stdio.h><conio.h>
and uses function getch, but this file is Borland specific, so it works in Turbo C compiler but not in GCC. The program for GCC must be like: Vegas movie studio serial number.int main()
{
int c;
{
int c;
/* for loop */
for(c =1; c <=10; c++)
printf('%dn', c);
return0;
}
printf('%dn', c);
return0;
}
If you are using GCC, save the program in a file say 'numbers.c' to compile the program, open the terminal and enter the command 'gcc numbers.c', this compile the program and to execute it enter the command './a.out' do not use quotes while executing commands. You can specify the output file name as 'gcc numbers.c -o numbers.out', to run execute './numbers.out' in the terminal.
C programming tutorial
A program consists of functions that contain instructions given to a machine to perform a task. The process of writing it includes designing an algorithm, drawing a flowchart, and then writing code. After writing it, you need to test it and debug it if it does not produce the required output.
To write a program, you need a text editor (use your favorite one) and a compiler. A compiler converts source code into machine code, which consists of zero's and one's only, ready to be executed on a machine.
An IDE (Integrated Development Environment) provides a text editor, compiler, debugger, etc. for developing programs and managing projects. Code::Blocks IDE provides an ideal environment for development. It can import Microsoft Visual C++ projects, is extendable as it uses plug-ins, open-source, and cross-platform.
How to write a C program?
A program must have at least one function which must be main. A function consists of declarations and statements. A statement is an expression followed by a semicolon. For example, a + b, printf('C program examples') are expressions and a + b; and printf('C is an easy to learn computer programming language'); are statements.
How To Make A Classes In Dev C++
To use a variable, we must indicate its type, whether it is an integer, float, character, or others. C language has many built-in data types, and we can create our own using structures and unions. Every data type has its size that may depend on the machine; for example, an integer may be of 2 or 4 Bytes. Data is stored in a binary form, i.e., a group of bits where each bit can be '0' or '1'.
Keywords such as 'switch,' 'case,' 'default,' 'register,' are reserved words with predefined meaning and can't be used as the name of a variable or a function. Memory can be allocated at compile-time or run-time using malloc and calloc functions. C language has many features such as recursion, preprocessor, conditional compilation, portability, pointers, multi-threading by using external libraries, dynamic memory allocation. Thanks to these, it is used for making portable software programs and applications. Using networking API's users can communicate and interact with each other and share files.
C standard library contains functions for mathematical operations, characters, input/output, files, and many more. The process of making a program which is known as coding requires knowledge of programming language and logic to achieve the desired output. So you should learn C programming basics and start making programs.
https://sitepub952.weebly.com/blog/looking-for-freeware-alternative-to-little-snitch. Learning data structures (stacks, queues, linked lists) using C provides you a greater understanding as you learn everything in detail. A general belief is to go for high-level languages. However, it's a good idea to learn C before learning C++ or Java. C++ is object-oriented and contains all features of C, so learning C help you learn C++ quickly, then you can study Java.
