Relational Operator
>
>=
<=
==
no1=5
no2=3
no1>no2 = true 1
false 0
Control Statement
no=5
rem = no%2
if(condition)
{
}
if - else

{
}
else
{ }

#include< stdio.h >
#include< conio.h > void main() { int no;
int rem;

4. INTRODUCTION TO BITWISE OPERATOR

/*
Bitwise Operator
&
|
!
<< shift left
>
>
shift right
a=5 101
b=3 011
& 001 = 1
| 111 = 7
^ 110 =6
a=101 =5
1010=10
a=101
10=2
1=1
*/
#include< stdio.h >
#include< conio.h >
void main()
{ int a=5,b=3,c; clrscr();
c = a&b; printf("C(a&b) : %d",c);
c= a|b; printf("nC(a|b) : %d",c);
c=~a; printf("nC(~a) : %d",c);
c = a^b; printf("nC(a^b) : %d",c);
c=a<<2; printf("nC(a<<1) : %d",c);
c=a>>2; printf("nC(a>>2) : %d",c);
getch();

5. INTODUCTION TO TERNARY OPERATOR

/*
condition?true:false
*/
#include< stdio.h >
#include< conio.h >
void main()
{
int no1,no2,max;
clrscr();
printf("Enter No1 : ");
scanf("%d",&no1);
printf("Enter No2 : ");
scanf("%d",&no2);
max = (no1>no2)?no1:no2;
printf("nMAX : %d",max);
getch();
}

6. INTODUCTION TO GOTO OPERATOR

#include< stdio.h >
#include< conio.h >
/*
label:
goto label; */
void main()
{
int no;
clrscr();
back:
printf("Enter No : ");
scanf("%d",&no);
if(no%2==0)
goto back;
printf("nNO is : %d",no);
getch();
}

7. W.A.P TO CHECK WHETHER ENTERED DATA IS NUMBER OR DIGIT

#include< ctype.h >
{
char ch;
clrscr();
ch = getchar();
if(isalpha(ch)>0)
{

printf("It is character.");
}
else if(isdigit(ch)>0)
{
printf("It is digit");
}
else
{

printf("It is not character and not digit.");
}
getch();
}

8. W.A.P TO CHECK WHETHER ENTERED NUMBER IS A LEAP YEAR OR NOT

#include< stdio.h >
#include< conio.h >
void main()
{
int a;
clrscr();
printf("Enter the year:");
scanf("%d",&a);
if (a%4==0)
{
printf("IT is a leap year");
}
else if (a@0==0 && !(a0==0))
{
printf("IT is a leap year"); }
else
{
printf("It is not a leap year");
}
getch();
}

9.W.A.P TO CTEATE A SIMPLE CALCULATOR USING RELATIONAL OPERATOR

/*
This program read the no from user and display it
Arithmetic operator
+
-
*
/
%
5/3 = 1
5%3 = 2
*/
#include< stdio.h >
#include< conio.h >
void main()
{
int a,b;
int sum,sub,mul,div,mod;
// int b;
clrscr();
printf("Enter No1 : ");
//To get the no from user
scanf("%d",&a);
printf("Enter No2 : ");
scanf("%d",&b);
sum = a+b;
sub =a-b;
mul = a*b;
div = a/b;
mod = a%b;
printf("nNo1 is : %d",a);
printf("nNo2 is : %d",b);
// printf("nADDITION : %d",sum);
printf("nAddition of %d and %d is %d",a,b,sum);
printf("nSUBTRACTION : %d",sub);
printf("nMULTIPLICATION : %d",mul);
printf("nDIVISION : %d",div);
printf("nMODULO : %d",mod);
getch();

}

10. SWAPPING OF NUMBERS

#include
#include
void main()
{
int a=4,b=3,temp;
clrscr();
printf("n before A:%d t B:%d",a,b);
temp=a;
a=b;
b=temp;
printf("n after A:%d t B:%d",a,b);
getch();
}

11. W.A.P FOR ADDITION OF ALL DIGITS IN A GIVEN NUMBER

#include< stdio.h >
#include< conio.h >
void main()
{
int no,sum,rem;
clrscr();
sum=0;
printf("ENTER NO :");
scanf("%d",&no);
while(no>0)
{
rem = no % 10;
sum + = rem;
no / = 10;
}
printf("THE SUM OF DIGITS IS :%d",sum);
getch();

}

12. W.A.P TO PRINT REVERSE OF A NUMBER SO ENTERED BY THE USER

#include< stdio.h >
#include< conio.h >
void main()
{
int no,sum,rem;
clrscr();
sum=0;
printf("ENTER NO :");
scanf("%d",&no);
while(no>0)
{
rem = no % 10;
sum = ( sum * 10 )+ rem;
no / = 10;

} printf("n REVERSE IS %d",sum);
getch();

}

13. W.A.P TO CHECK WHETHER A NUMBER SO ENTERED IS ARMSTRONG NUMBER, EXAMPLE IS 153=1*1 + 5*5 + 3*3

#include< stdio.h >
#include< conio.h >
void main()
{
int no,temp,sum,rem;
clrscr();
printf("n Enter the No.:");
scanf("%d",&no);
temp=no;
sum=0;
while(no>0)
{ rem = no % 10;
sum = sum + ( rem * rem * rem);
no = no / 10; } if( temp == sum)
{ printf("n %d is armstrong",temp);
else
{ printf("n %d is not armstrong",temp); }
getch();

}

14.W.A.P TO GET BASE AS WELL AS POWER FROM THE USER AND ITS VALUE

#include< stdio.h >
#include< conio.h >
void main()
{
int a,b,temp=1,i;
clrscr();
printf("n Enter a & b for a^b:");
scanf("%dt%d",&a,&b);
for(i=1;i<=b;i++)
{ temp=temp*a; }
printf("n RESULT IS:%d",temp);
getch();

}
