Acknowledgment

I would like to express my special thanks of gratitude to my teachers as well as our principal who gave me the golden opportunity to do this wonderful project, which also helped me in doing a lot of Research and I came to know about so many new things. I am really thankful to them.

Secondly I would also like to thank my parents and friends who helped me a lot in finishing this project within the limited time.

I am making this project not only for marks but to also increase my knowledge.

THANKS AGAIN TO ALL WHO HELPED ME.

No Of Digits in Number

#include<conio.h>

void main()

{

clrscr();

int x=0,n;

cout<<"Enter the number :";

cin>>n;

while(n>0)

{

n=n/10;

x=x+1;

}

cout<<"The no of digits are :"<<x;

getch();

}

Output:-

Decimal to Binary & viceversa
