Escape Sequence

#include<stdio.h>

#include<conio.h>

void main()

{

clrscr();

printf("feel_the_coder\n"); // \n is the escape sequence

printf("Subscibe Us\a"); // \a is also a escape sequence for a audible/visible alert

printf("Give me space\t"); // \t is escape sequence and moves cursor to next horizontal tab

getch();

}

Operators

#include<stdio.h>

#include<conio.h>

void main()

{

int a,b,c; // variables

a=10;

b=5;

c=a+b;

clrscr();

if(a==10||b==6) // OR operator

printf("%d",c);

if(a==10&&b==5) // AND operator

printf("%d",c);

if(a!=b) // NOT operator

printf("%d",c);

getch();

}

Note - if() is a conditional statement which you will study in subsequent posts.
