Write a function int_to_binary that converts an integer to a character string that

is the binary representation of the integer. Adjust the 1s and 0s in the right-hand

portion of the string and pad the remainder of the string with blanks. The string

should contain no insignificant zeros, except that the integer 0 should produce the

string consisting of all blanks and one character “0”. If the integer is negative, the

first nonblank character should be a minus sign; if it is positive, the first nonblank

character should be ”1”. Declare the function result to have length 5. If the declared length is not long enough to contain the result, it should consist of all asterisks.

You should write the function in such a way that changing the length of the function result to 16 requires no additional changes in the function.
