Syntax of C Program

Syntax of C Program #include<stdio.h> //Header File void main(){ printf(“Hello”);//prints 'Hello' printf(“\n I am Devil”);//prints 'I am Devil' in New Line } Here is the simple example of Syntax in C program First Line is #include<stdio.h> is the HeaderFile. Then after void is the data type which returns nothing. Then Main() is the Function. C program always start from here. And Next Printf is the function which prints the string which is provide in the brackets. In the next printf function I used a ‘\n’ which is used for new Line. More Important thing is in the program is semicolon ‘;’ - It used to end the current statement. Here, Statement means one line of code wrote abobe. For ex , printf(“Hello”) -> so this is a single statement and we must provide the ‘;’ at the end of statememt. If I forgot to put semicolon at end of statement then compile takes this as single Statement and gives a compile time error because of th...

C Programming - The First Program

My First C Program. I can't wait to execute... Let's Begin Before we begin, let's talk about program. First we make simple program which prints a simple message as you want. I Like to print 'Hello Devil' on my Screen. One more - The File which is stored our program is saved with '.c' extention. For ex, I want to save my File as 'HelloDevil'. so, i simply put '.c' after the name Like 'HelloDevil.c' Let's Start... Program - HelloDevil.c #include<stdio.h> #include<conio.h> void main() { clrscr(); printf("Hello Devil."); getch(); } Output: Hello Devil. Program Explaination: The First main thing is to add header files, without it we can't run our program. The first Header file we uses is a <stdio.h> which is a standard input output header file which contains all the functions related to input and output. 2nd is <conio.h> is used for Console input and out...
