Logical operators in c

Using logical operators we can check multiple conditions .this condition has two answers true or false ,for example “3 is odd or even number” the answer is true .there are so many multiple conditions in logical operators .these are shown in table 2

Operator	Meaning	Example
&&	Logical AND	If c=1 and d=2 then, (c==1) && (d>1) equals to 0
||	Logical OR	If c=1 and d=2 then, (c==1) || (d>1) equals to 1.
!	Logical NOT	If c =1 then, expression ! (c == 1) equals to 0.

if there are two conditions .the logical operators works as shown in below table

logical operator	first condition	second condition	result
&&	true	true	true
&&	true	false	false
&&	false	true	false
&&	false	false	false
||	true	true	true
||	true	false	true
||	false	true	true
||	false	false	false

example:

#include <stdio.h>

int main()

{

int a = 5, b = 5, c = 10, result;

result = (a = b) && (c > b);

printf("(a = b) && (c > b) equals to %d \n", result);

result = (a = b) && (c < b);

printf("(a = b) && (c < b) equals to %d \n", result);

result = (a = b) || (c < b);

printf("(a = b) || (c < b) equals to %d \n", result);

result = (a != b) || (c < b);

printf("(a != b) || (c < b) equals to %d \n", result);

result = !(a != b);

printf("!(a == b) equals to %d \n", result);

result = !(a == b);

printf("!(a == b) equals to %d \n", result);

return 0;

}

(a = b) && (c > b) equals to 1

(a = b) && (c < b) equals to 0

(a = b) || (c < b) equals to 1

(a != b) || (c < b) equals to 0

!(a == b) equals to 1

!(a == b) equals to 0
