Learn how to write a C program to check whether a number is perfect or not. Step-by-step tutorial with code examples and explanations.
Any number can be the perfect number in C if the sum of its positive divisors excluding the number itself is equal to that number. For example, 6 is a perfect number in C because 6 is divisible by 1, 2, 3, and 6. So, the sum of these values is 1+2+3 = 6 (Remember, we have to exclude the number itself.
Feb 22, 2024 · A perfect number is a positive integer equal to the total of its positive divisors, except the number itself in number theory. For example, 6 is a perfect number since 1 + 2 + 3 equals 6. Some of the first perfect numbers are 6, 28, 496, and 8128.
C Program to Check Perfect Number. A perfect number is a positive integer number in which sum of all positive divisors excluding the number itself is equal to that number. For example: 28 is perfect number since its divisors are 1, 2, 4, 7 and 14. Sum of divisors is: 1+2+4+7+14=28.
Jan 10, 2024 · A perfect number is a positive integer that is equal to the sum of its proper divisors (excluding itself). In this tutorial, we will delve into a C program designed to check whether a given number is a perfect number. The program involves finding the sum of the proper divisors and comparing it with the original number. Example.
In this tutorial, we will learn how to find if a number is perfect or not by using C programming language. A positive number is called a perfect number if the sum of its proper positive divisors is equal to the number. For example, 6 is a perfect number.
