Operators in C Programming and Its Types | C Programming Language

Operators in C Programming: -

An operator in general is a symbol that operates on a certain data types. An operator is a symbol that tells the compiler to perform specific mathematical or logical functions.

The types of operators are: -

Arithmetic Operators in C Programming-:

             The arithmetic operators performs arithematic operations. The arithmetic operator is given below:-

(+) - Addition

(-) -Subtraction

(*)- Multiplication

(/)- Division

(%) - Modulo Division

 

Relational operators in C Programming:-

            Relational operators are used to compare logical, arithmetic and character expression. A list of relational operators is give below:-

(<)            Less than

(>)           Greater than

(< =)         Less than or equal to

(> =)        Greater than or equal to

(==)             Equal to

(! =)             Not equal to

Logical Operators in C Programming: -

            An expression logical operator returns either 0 or 1 depending upon whether expression is used to calculate the value of logical expression. There are three types of logical operators in C language. They are:-

(&&)     logical AND

(||)     Logical OR

(!)      Logical NOT

 

Assignment Operator in C Programming

          An assignment operator is used to form an assignment expression, which assigns the value to an identifier. The most commonly used assignment operator is = (equal to.). it is written in the form.

Identifier = expression;

Example: - i=100; j=200;

 

Increment and Decrement operator in C Programming

            Increment and decrement operators are unary operators that add or subtract one form their operands respectively. The increment operator ++ which adds 1 to its operand and the decrement operator -- which subtracts 1 from its operands.

 

Conditional Operators in C Programming

            Conditional operators which is also called ternary operator can be used as shorthand for some if-else statements. The operator consists of two symbols: the question mark (?) and the colon (:).

The general syntax of the conditional operator is:

Identifier = (test expression)? Expression 1: Expression 2;

Program

#include<stdio.h>
#include<conio.h>
 int main()
{
 int
 a,b;
 printf(" Enter an integer number:\n ");
 scanf("%d",&a);
 (a%2==0)?printf("\n %d is an even number.",a):printf("\n %d is an odd number.",a);
 return 0;
}

OUTPUT

Size of operators in C Programming

            This operator returns the size of its operands in bytes. The size of operator always precedes its operand. The operand may be an expression or it may be a cast.

For example, in C programming: - 

i= integer 

char= character

printf("Size of integer :",sizeof(i));

printf("Size of character:",sizeof(char));

Program:-

#include<stdio.h>

#include<conio.h>

int main()

{

int integerType;

float floatType;

double doubleType;

char charType;

printf("Size of int: %ld bytes\n",sizeof(integerType));

printf("Size of float: %ld bytes\n",sizeof(floatType));

printf("Size of double: %ld bytes\n",sizeof(doubleType));

printf("Size of char: %ld byte\n",sizeof(charType));

return 0;

}
