This program converts all the decimal numbers in an array to binary.
To convert a decimal number into binary, we follow the following steps:
Divide the decimal number by 2 and note the remainder
Divide the Quotient repeatedly by 2 and note the remainders till quotient is 0
Write remainder side by side in reverse order to know the binary number
For example 18
18 divide by 2 leaves quotient 9 remainder 0
9 divide by 2 leaves quotient 4 remainder 1
4 divide by 2 leaves quotient 2 remainder 0
2 divide by 2 leaves quotient 1 remainder 0
1 divide by 2 leaves quotient 0 remainder 1
So binary of 18 is 10010
