Question

12. Write a program that print a table of the binary(out of four digit) octal and hexadecimal equivalents of the decimal number in the rang 1 to 15.

Answer 1

Is that a question or a demand. :)

You don't state which language.

#include
int main()
{
int x;

for (x=1; x<=15; x++)
printf("%d: Oct=[%o]\tHex=[%x]\n",x,x,x,x);
}

Oh, and to print binary value, you'll need to write a little routine for that. (Come on - you gotta do some of your own homework.)
