Count a number of digit in a Number using C Programming

Q20. Write a program to read a long integer from a user and count a number of digits of it.

==> Code goes like this :
/* Counting digits in a integer */
#include<stdio.h>
int main()
{
long long num;
int count=0;
printf("\n Enter a number:");
scanf("%lld",&num);
while(num!=0)
    {
        count++;   //incrementing count
        num/=10;   //removing the last digit
    }
    printf("\n Total digit=%d",count);
    return 0;   
}

Output:

I have used Dev CPP to compile this program.
If you are using Turbo C++ IDE, then use conio.h in link section after stdio.h
and use getch(); to hold the output screen, just before the end of main function.
If you have any confusion regarding the program, please, comment below.
Happy Coding !
Thank you
