# Write a c program to convert decimal to binary using array The decimal system dealt with base 10, while the binary system operates in base 2. The columns in the binary system are different. Each switch in the computer can be represented by a bit binary digitbut the entity that it represents may not even be a number, much less a number in the binary number system.

But in the binary system, you get only 3 digits By convention, we use a positional notation when writing numbers. The decimal system uses 0 to 9 digits to represent numbers.

### C program to convert decimal to binary using user defined function

We can specialize Equation 2. In this example program, we used the loop function and then used it to reverse an array. The concept for converting a binary number is simpler. The binary number was stored inside an array and then, with the help of a loop and multiplication, we converted it into a decimal number. Every time you run out of digits, you shift the number 1 one column to the left and start with 0 again. The decimal system dealt with base 10, while the binary system operates in base 2. The decimal system uses 0 to 9 digits to represent numbers. For example, the eight-digit binary number is interpreted as 2. Algorithm 2. Showing the mathematical equivalence of the hexadecimal and decimal number systems is left as exercises at the end of this chapter. The remainder of this division will be stored in an array form. Each switch in the computer can be represented by a bit binary digit , but the entity that it represents may not even be a number, much less a number in the binary number system. Who knows, you may end up making the next Angry Birds! The base or radix of the decimal number system is ten.

Say we wish to convert a unsigned decimal integer, N, to binary. Moving a digit one place to the left increases its value by a factor of ten, and moving it one place to the right decreases its value by a factor of ten.

### C program to convert decimal to binary using user defined function

It is stated in Algorithm 2. After all, practice makes perfect. The number 0 will look like this: 0 The number 1 will look like this: 1 The number 2 will look like this: 10 The number 3 will look like this: 11 The number 4 will look like this: Going by this system, the number will be: Unsigned numbers have no sign. The binary number was stored inside an array and then, with the help of a loop and multiplication, we converted it into a decimal number. While we used a calculator for this, the method followed to convert this number to the binary form is known as the short division by two method, with remainder. The columns in the binary system are different. For example, in the decimal number system, the integer is taken to mean 2.

It is stated in Algorithm 2. Later, we use a loop to reverse the array and then print out the result. In this example program, we used the loop function and then used it to reverse an array.
