C Program To Convert Decimal Number To Binary Number, using While Loop

Lets write a C program convert a number from Decimal number system(base 10) to Binary number system(base 2), using while loop.

Note: Binary number system can be derived by base 2 to the power of whole numbers.

Expected Output for the Input
User Input:
Enter a decimal number
14

Output:
Binary equivalent of 14 is 1110

Thank you. Great explanation and it made a lot of sense how you went through the logic. As soon as you introduced your variables I realized why my code wasn’t working. Thank you great vid

[srps]

sir, when you are calculating the 19th decimal into binary equivalent, you got the wrong number like 16+8+4+2+1=31. how it is possible?

[loriejanedialoring]

Hi! Can you do a sample loop using java same problem decimal to binary. Thank you

[Im_RajSingh]

Sir actually binary representation of 8 is 1000, at start there was a error in ur chart, 2%2 is 0 and not 1

[dlwpdle]

Sir why we use printf bin ??and why its outside of loop?

[dvatsetsem]

I dont understand why we need place = place * 10?
what is have us? +

[jesusstudentbrett]

awesome work!! the text of the C code was so nice and large!! so clear... great job!!! clap clap clap clap!!!

[tinula]

Dear sir, Can you explain a c program to find my lucky number once i enter my birthday as, year, month, date. (lucky number = year+ month+date, and digit adding continue until gets lucky number that is single digit integer") thank you

[bishalbhandari]

How can i make it 8 bits binary for example if number is 5 instead of 101, i want it to be like

[partiid]

Yeah, what about the numbers that are above the range of Int? It sucks.

[kuntalsur]

You have made it so complex. No need to do with bin & place. It can be done only by num & rem.

[RohitKumar-oigc]

when I am putting 4 digit program, not working as a decimal to binary idkw

[factworldpresents]

Where is decimal number input
While(num) X
While (num!=0) correct

[murieldebonaportonguarezi]

When I use a high number, like 2000, the algorithm returns a wrong number, how can I solve this?

[goldenwind]

Only able to convert 2 digit nos not 3 digit

[mohithmvs]

u said decimal but u are doing only for integers. Change your title please

[EternalBlaze]

The flaw of this program is, if the binary number starts with 0, it wont print it
