C Syntax

Syntax defines the set of rules for writing programs. Every language specification defines its own syntax.

A program in C-Language can be composed of:

  • Variables − Represents a named in memory block that can store values for the program.
  • Literals − Represents constant/fixed values.
  • Operators − Symbols that define how the operands will be processed.
  • Keywords − Words that have a special meaning in the context of a language.

First C Program

#include<stdio.h>
#include<conio.h>
void main()
{
    clrscr();
    printf("This is my first C Program"); /*to print the statement*/
    getch();
}

Code Explanation

  • stdio - Standard input output
  • .h - header file
  • conio - Console input output
  • main is a function from where a program start its execution.
  • { } - curly brackets define the scope of the program
  • printf() is a function which is use to print the string
  • scanf() function is use to receive the values from user
  • & means address of a variable
