how can i make a program that counts a number multiple by two?

[Ancient Dragon]

create a for loop and increment the loop counter by two -- inside he loop call printf() to display the value of the loop counter.

Or maybe I misunderstood the question.

get a number from the keyboard
multiply it by 2
call printf() to display the result

for(i=0;i<sizeof(num)/2;i++)

Wong. You fail the test. sizeof(int) may or may not be 2, depending on your compiler.

Sorry for that you can use this

for(i=0;i<sizeof(num)/sizeof(int);i++)

instead of

for(i=0;i<sizeof(num)/2;i++)

now it will work at any computer sorry for not considering this fact.
