Thread: if

Code:

 int input;
 scanf("%d",&input);
 if(3%2) // I don't know what this means
 printf("A");
 if(2%2) // I don't know what this means
 printf("B");

thanks

the "%" operator is called the "modulus operator".it gives the remainder after dividing two numbers..
example ---> 3%2 == 1 ( since remainder is 1)

if(3%2) // Is it equal to if(TRUE)
if(2%2) // Is it equal to if(FALSE)

you have to use a condition..like..

Code:

if(3%2 == 1)
{
  printf("A");
}
else
{
 printf("B");
}

the above statement prints A because 3%2 == 1 is true..

but i read my note which is just if(3%2) i don't know the meaning of this

Code:

if(condition)

is a conditional statement. If the condition results in logical 0 then the body of the loop won't be excuted whereas if the condition is logial 1 then the body of the loop will be executed.
Example:

Code:

if(1>2)
{
}

Here the body of the loop wont be executed.

Code:

if(2>1)
{
}

Here the body of the loop will be executed.

In your example '%' is modulus operator. Read more about it you'll know the answer.

get it thanks
