In this post we will learn how to write a C Program to Convert Decimal Numbers to Binary Numbers.

*Example 2*

Convert the decimal number 35 to binary.

*Solution*

Write out the number at the right corner. Divide the number continuously by 2 and write the quotient and the remainder. The quotients move to the left, and the remainder is recorded under each quotient. Stop when the quotient is zero.

0 <- 1 <- 2 <- 4 <- 8 <- 17 <- 35 Dec.

**Binary 1 0 0 0 1 1 **
