Arithmetic operators

By -

Arithmetic operators are:

  1. * (Multiply), /(divide), %(Modulas)-It's priority is most
  2. + -         It's priority is least.
i) Multiplication Operator:
  • This operator multiplies two operands.
  • If in any expression if there is * (multiplication) and + (Addition). Then according to precedence rule * (multiplication) is first solved.
  • If in arithmetic operators, operators are the same then it is solved from left to right.
  • i.e its associativity is left to right.

Program

#include <stdio.h>
#include<conio.h>
int main()
{
    int a;
    a=2*3;
    printf("Answer of multiplication operator is %d",a);
    getch();
}
Output:
Answer of multiplication operator is 6

ii) Integer divide Operator:
Examples:

 2/3 ? = 0
Instead of 0.6.
13/2 =6
instead of 6.5.

Because in c language if any operations are performed between two integers. then, our result will be in integer.

Program:

#include <stdio.h>
#include<conio.h>
int main()
{
    int a;
    a=2/3;
    printf("Answer of Integer divide operator is %d",a);
    getch();
}
Output:
Answer of Integer divide operator is 0


iii) Modulo Operator:

The remainder obtained after the division operation on two operands is known as modulo operation.
The operator for doing modulus operation is "%".
Ex. a%b=c

where c is the remainder obtained when a is divided by b.

 Example:
 2%3 ? = 2
Instead of 0.6/0
13%2 = 1
instead of 6.5.

Program:

#include <stdio.h>
#include<conio.h>
int main()
{
    int a;
    a=2%3;
    printf("Answer of modulo operator is %d",a);
    getch();
}
Output:
Answer of modulo operator is 2

iv) Addition and subtraction operator:


4+1-2
It is solved from left to right and ans. is 3.
Here + is operated first.


4-2+1
it is solved from left to right and ans. is 3.
Here - is operated first.

Program

#include <stdio.h>
#include<conio.h>
int main()
{
    int a;
    a=4-2+1;
    printf("Answer of Addition and subtraction operator is %d",a);
    getch();
}
Output:
Answer of Addition and subtraction operator is 3

Getting input in C

By -
                 Getting input in C There are two ways to get input from user in C language. 1) By scanf() function 2) By gets() or fgets() function 1. By scanf() function:-            The standard input-output header file named stdio.h   contains the definition of the function printf()   and scanf(), which are used to display on the screen and to take input from user. Program:-   #include < stdio . h > void main ( ) { // defining a variable int x ; /* displaying message on the screen asking the user to input a value */ printf ( "Please enter a value..." ) ; /* reading the value entered by the user */ scanf ( "%d" , &x ) ; /* displaying the number as output */ printf ( "\nYou entered: %d" , x ) ; } Output:- Please enter a value... The Output was aski...

Unary Operator

By -
What is a Unary Operator? Unary Operators are the operators which require only one operand. While binary operator requires two operands and tertiary requires three operands. Unary operators are: +, -, ++, --, sizeof() 1) + and -   Note: (+) and (-) are not of addition and subtraction but it denotes only sign of operator as positive or negative. Ex. +1, +2, +3... -1, -2, -3... 2) ++ and -- It seems to be  ++ (two plus-plus), But it is a single operator. It is called the increment operator . Increment operator are of two type: i) Pre increment ii) Post increment The meaning of both the increments is the same. i.e To add +1 in  any value x++ or ++x; or to increase the value by 1. x++ is x=x+1 where x is a variable. Example: 7++ output is 8 25++ output is 26 program: (Pre-increment)  #include <stdio.h> #include <conio.h> int main() {     int x=7;     ++x;  / /Whe...
