After writing it, you need to test it and debug it if it does not produce the required output. The process of writing it includes designing an algorithm, drawing a flowchart, and then writing code. & #13 Ī program consists of functions that contain instructions given to a machine to perform a task. You can specify the output file name as 'gcc numbers.c -o numbers.out', to run execute './numbers.out' in the terminal. 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. For example, consider the following program that prints the first ten natural numbers. If you are using GCC on Linux operating system, then you may need to modify the programs. How to compile C programs with GCC compiler? Outtextxy ( 10, 20, 'Graphics programming is fun!' ) & #13 Initgraph ( & gd, & gm, 'C: \TC \BGI' ) & #13 Printf ( 'First %d terms of Fibonacci series are: ', n ) & #13 Įxample 12 - C graphics programming & #13 Printf ( 'Enter the number of terms ' ) & #13

Int n, first = 0, second = 1, next, c & #13 My_function ( ) // Calling the function Void my_function ( ) // Declaring a function Printf ( 'Enter %d elements ', n ) & #13 Printf ( 'Enter number of elements in array ' ) & #13 This program prints the number of arguments and their contents. Printf ( 'Number of command line arguments passed: %d ', argc ) & #13 Int main ( int argc, char *argv ) & #13 Int c = 1 // Initializing variable Įxample 5 - C program check if an integer is prime or not & #13 Įxample 6 - command line arguments & #13
