Ternary and Assignment Operators in C Language

Ternary and Assignment Operators in C Language

Ternary Operator (?:)

A conditional operator is a ternary operator, that is, it work on 3 operands.

Syntax

conditional Expression ? expression 1 : expression 2

Working of Conditional operator :-

• The first expression conditional Expression is evaluated first. This expression evaluates to 1 if it's true and evaluates to 0 if it's false.

• If conditional Expression is true, expression 1 is evaluated.

• If conditional Expression is false, expression 2 is evaluated.

Example :

#include <stdio.h>
int main ()
{
char february;
int days;
printf(" if this year is leap year, enter 1. if not enter any integer: ");
scanf(" %c", & february);

days = (february == '1') ? 29 : 28;

printf(" number of days in february = %d", days);
return 0;
}

Output

if this year is leap year, enter 1. if not enter any integer: 1
Number of days in february = 29

Assignment Operator

An assignment operator is used for assigning a value to a variable. The most common assignment operator is '='.

Operator	Example	Same as
=	a = b	a = b
+=	a += b	a = a+b
-=	a -= b	a = a-b
*=	a *= b	a = a*b
/=	a /= b	a = a/b
%=	a %= b	a = a%b

Example -

#include <stdio.h>
int main()
{
int a =5, c;
c=a;
printf(" c = %d \n", c);

c + = a; // c= c+a

printf(" c = %d \n", c);

c - = a; // c= c-a

printf(" c = %d \n", c);

c *= a; // c= c*a

printf(" c = %d \n", c);

c /= a; // c= c/a

printf(" c = %d \n", c);

c % = a; // c= c%a

printf(" c = %d \n", c);

return 0;
}

Output

c = 5
c = 10

c = 5

c = 25

c = 5
c = 0
