any one good at programming ?

Question

i wanna write a program in borland c language when the user write a even number the program print this number is even and if else else print to the user this number is odd how i can make the computer characterize which is even and which is odd

Answer 1

Use the modulo (%) character. The modulo is like a division character but it only returns a 0 or 1.

0=no remainder
1=remainder

Example:
input: 67
------------------------------------
number = 67;

if((67%2)=0){
printf("the number %d is even", number);
}
else{
printf("the number %d is odd", number);
}

In the above example, when you express (67%2) this returns a 1 since there is a remainder. Therefore, 1=0 is a false statement and the program will print the line in the else block.

Answer 2

very simple...two ways to find it out...

you can take the mod % of the entered number by 2
if the answer is 1 then its an odd number, else its an even number

secondly you can divide the entered number with 2

if the result is integer...the number is even, if the result is float, the result is odd

Answer 3

just another unique way would be:

int number;
//get input
if (number & 0x1)
printf("number is odd");
else
printf("number is even");
