41 : C Program to Count number of digits of entered Number

Check out the complete list of c-programs : C Program List    



This C program accepts a integer and counts the number of digits.

Variables :

1. number : Datatype int : Holds value of number inputted by the user.

2. temp_var : Datatype int : To hold temporary values.

3. sum : Datatype int : Holds result ie no. of digits.



Functions :

printf() : is used to display something on the console/screen. Format specifier %d in printf function is used to display a int variable on screen and %f for float. \n is used to add a newline

scanf() : is used to fetch data inputted by the user on the console/screen using keyboard. %d in scanf is indicates that inputted text is of type int.



Logic : 


   while(number >= 1 ) {
       
      temp_var = number%10; //get unit place digit
      sum = sum + 1; //increment the digit count by 1
      number = number/10; //remove the last digit
       
       
   }
