Question
Vivek wants to count the number of digits in the given integer and find the sum of the first and last digits of the number. Write a suitable program to complete the above task using a for loop.
Solution
Sure, here is a Python program that completes the task:
def count_digits_and_sum_ends(n):
# Convert the integer to a string to easily access digits
n_str = str(n)
# Count the number of digits
num_digits = len(n_str)
# Find the sum of the first and last digits
sum_ends = int(n_str[0]) + int(n_str[-1])
return num_digits, sum_ends
# Test the function
n = 12345
num_digits, sum_ends = count_digits_and_sum_ends(n)
print(f"The number of digits in {n} is {num_digits}.")
print(f"The sum of the first and last digits of {n} is {sum_ends}.")
This program defines a function count_digits_and_sum_ends that takes an integer n as input. It converts n to a string to easily count the number of digits and access the first and last digits. It then returns the number of digits and the sum of the first and last digits. The program then tests this function with the number 12345.

Problem StatementVivek wants to count the number of digits in the given integer and find the sum of the first and last digits of the number. Write a suitable program to complete the above task using a for loop.ExampleInput:1221Output:Sum = 2Digits = 4Explanation:Counting Digits: The number 1221 has 4 digits.First and Last Digits: The last digit is 1 (1221 % 10). To find the first digit, divide 1221 by 10 repeatedly until it's less than 10. The first digit is 1.The sum is 1 + 1 = 2.Note: This question helps in clearing coding technical tests for service-based companies.Input format :The input consists of an integer n.Output format :The first line prints "Sum = " followed by an integer which is the sum of the first and last digits.The second line prints "Digits = " followed by an integer which is the number of digits.Refer to the sample output for the formatting specifications.Code constraints :In this scenario, the test cases fall under the following constraints:10 ≤ n ≤ 10000Sample test cases :Input 1 :1221Output 1 :Sum = 2Digits = 4Input 2 :10Output 2 :Sum = 1Digits = 2Input 3 :10000Output 3 :Sum = 1Digits = 5
Write a C program to calculate sum of digits of a number. – using while loop
Write a C program to count number of digits in a number. Using do-while loop
#include<stdio.h> int main(){ int number,sum=0,digit; printf("Enter an integer : "); scanf("%d",&number); while (number != 0){ digit=number%10; sum += digit; number /= 10 } printf("The sum of digits of the given number "%d" = %d",number,sum); return 0; }
James, a mathematics teacher, is developing a programming exercise to help his students practice continuously summing the digits of a number until it becomes a single-digit integer. He wants to create a simple program using a 'while' loop that takes a positive integer input and generates the final single-digit result. Input format :The input consists of a positive integer n.Output format :The output prints "The single-digit sum of n is Y." where n is the input integer and Y is its single-digit sum.Refer to the sample output for formatting specifications.Code constraints :1 ≤ n ≤ 1010Sample test cases :Input 1 :456Output 1 :The single-digit sum of 456 is 6.Input 2 :999Output 2 :The single-digit sum of 999
