Why you are ask logical gates?

Answer 1

AND,OR,NOT

AND(&&): if both statements are true, result is also true,else false

OR():either one statement must be true for result to be true

NOT(!):opposite/reverse of i/p

Example:

int i=5;

if(i==5&&i>3)

printf("true");

here 5==5 and greater than 3 also;result is true

NOT:

int i=0;

if(!i==1)

printf("true");

here NOT(1) is 0 same as NOT(TRUE)=FALSE

NOT(0) is 1 same as NOT(FALSE)=TRUE
