Operators in C

Operators:

1.    Arithmetic Operator

2.    Unary Operator

3.    Relational and Logical Operator

4.    Assignment Operator

5.    Conditional Operator

1.    Arithmetic Operator:

+, -, *, /, %

2.    Unary Operator:

++, --, SizeOf

++ = Increment Operator

-- = Decrement Operator

Prefix increment = ++i

Postfix increment = i++

Prefix decrement = --i

Postfix decrement = i--

3.(a). Relational Operator:

>, <, >=, <=, = =, !=

3.(b). Logical Operator:Char3

&&, ||, !

&& = Logical AND

|| = Logical OR

! = Logical NOT

4.Assignment Operator:

+=, -=, *=, /=, %=

5. Conditional Operator OR Ternary Operator: Chap5

?, :

Arithmetic Operator:

#include<stdio.h>

#include<conio.h>

void main()

{

int a,b,c;

clrscr();

printf(“Enter a values:”);

scanf(“%d”,&a);

printf(“Enter b values:”);

scanf(“%d”,&b);

c=a+b;

printf(“Answer=%d”, c);

getch();

}

Unary Operator:

PreFix Increment:

#include<stdio.h>

#include<conio.h>

void main()

{

int i;

i=2;

clrscr();

printf(“i=%d\n”,i);

printf(“i=%d\n”,++i);

printf(“i=%d\n”,i);

getch();

}

Output:

I=2

I=3

I=3

PostFix Increment:

#include<stdio.h>

#include<conio.h>

void main()

{

int i;

i=2;

clrscr();

printf(“i=%d\n”,i);

printf(“i=%d\n”,i++);

printf(“i=%d\n”,i);

getch();

}

Output:

I=2

I=2

I=3

PreFix Decrement:

#include<stdio.h>

#include<conio.h>

void main()

{

int i;

i=2;

clrscr();

printf(“i=%d\n”,i);

printf(“i=%d\n”,--i);

printf(“i=%d\n”,i);

getch();

}

Output:

I=2

I=1

I=1

PostFix Decrement:

#include<stdio.h>

#include<conio.h>

void main()

{

int i;

i=2;

clrscr();

printf(“i=%d\n”,i);

printf(“i=%d\n”,i--);

printf(“i=%d\n”,i);

getch();

}

Output:

I=2

I=2

I=1

SizeOf:

#include<stdio.h>

#include<conio.h>

void main()

{

clrscr();

printf(“Integer=%d\n”,sizeof(int));

printf(“Float=%d\n”,sizeof(Float));

printf(“Char=%d\n”,sizeof(Char));

printf(“Double=%d\n”,sizeof(Double));

printf(“Long Int=%d\n”,sizeof(long int));

getch();

}

Output:

Integer   =     2

Float      =     4

Char      =     1

Double  =     8

Long Int       =     4    

Relational Operator:

#include<stdio.h>

#include<conio.h>

void main()

{

int x,y;

x=30;

y=5;

clrscr();

printf(“The value of x==y is %d\n”,x==y);

printf(“The value of x>=y is %d\n”,x>=y);

printf(“The value of x<=y is %d\n”,x<=y);

printf(“The value of x!=y is %d\n”,x!=y);

getch();

}

#include<stdio.h>

#include<conio.h>

void main()

{

int x,y;

x=30;

y=5;

clrscr();

printf(“The value of x+y is %d\n”,x+y);

printf(“The value of x-y is %d\n”,x-y);

printf(“The value of x*y is %d\n”,x*y);

printf(“The value of x/y is %d\n”,x/y);

getch();

}

Assignment operator:

#include<stdio.h>

#include<conio.h>

void main()

{

int x,y,z;

x=6*5;

y=8+7;

z=6-3;

clrscr();

printf(“X=%d\n”,x);

printf(“y=%d\n”,y);

printf(“z=%d\n”,z);

getch();

}
