C Programming
Write a C program that asks the user for a positive number n (n ≥ 1) then, the program displays all the perfect numbers up to (including) n. A number n is said to be a perfect number if the sum of all its positive divisors (excluding itself) equals n. For example, the divisors of 6 (excluding 6 itself) are 1,2 and 3, and their sum equals 6, thus, 6 is a perfect number. Display the numbers with a space separation and finish with a newline, as usual.
#include <stdio.h>
int main()
{
int n,j;
long long int s,i;
printf("Enter a positive number: ");
scanf("%d",&n);
if(n>=1){
for(j=2;j<=n;j++){
s=1;
for(i=2;i*i<j;i++)
{
if(j%i==0){
if(i*i!=n)
s=s+i+j/i;
else
s=s+i;
}
}
if(s==j && j!=1)
printf("%d ",j);
}
}
else
printf("Not a positive integer");
printf("\n");
return 0;
}

A positive integer is said to be a perfect number if it equals the sum of its positive divisors (excluding the number itself). As an example, 6 is aperfect number because its divisors, 1, 2, and 3 sum up to 6. The first four perfect numbers are 6, 28, 496, 8128. Write a C program that asks the user to enter a number and checks if the number is perfect. Your program should run interactively until the user quits. Try...
A perfect number is a positive integer that is equal to the sum of its (proper) positive divisors, including 1 but excluding itself. A divisor of a number is one which divides the number evenly (i.e., without a remainder). For example, consider number 6. Its divisors are 1, 2, 3, and 6. Since we do not include number itself, we only have 1, 2, and 3. Because the sum of these divisors of 6 is 6, i.e., 1 + 2...
A perfect number is a positive integer that equals the sum of all of its divisors (including the divisor 1 but excluding the number itself). For example 6, 28 and 496 are perfect numbers because 6=1+2+3 28 1 + 2 + 4 + 7 + 14 496 1 + 2 + 4 + 8 + 16 + 31 + 62 + 124 + 248 Write a program to read a positive integer value, N, and find the smallest perfect number...
Write a program that asks the user for a lower limit and an upper limit. The program finds all pairs of amicable numbers where the first number of the pair is between those limits. The second number of the pair may or may not be between the limits. To do this sensibly, write a function int sumDivisors( int num ); that returns the sum of all the proper divisors of num. The main program looks at each integer N between...
Use C programming Make sure everything works well only upload Write a program that takes an integer from standard input and prints all prime numbers that are smaller than it to standard output. Recall that a prime number is a natural number greater than 1 whose only positive divisors are 1 and itself. At the start of the program, prompt the user to input a number by printing "Input a number greater than 2:\n". If the user's input is less...
Using loops, write a C# program that asks the user to enter repeatedly an integer number, it stops when the user enters -1, then the program should display how many numbers were entered, their the sum and their average
Write a program that asks the user to enter a string and then asks the user to enter a character. The program should count and display the number of times that the specified character appears in the string. python programming
Please paste your code and a screenshot of your output! 1. An integer n is divisible by 9 if the sum of its digits is divisible by 9. Develop a program to determine whether or not the following numbers are divisible by 9: n= 154368 n 621594 n-123456 2. A number is said to be perfect if the sum of its divisors (except for itself) is equal to itself. For example, 6 is a perfect number because the sum of...
C# Programming: A. Write a GUI program named MultiplicationGUI whose Main() method asks the user to input an integer into a TextBox and then calls a method named MultiplicationTable() after the user clicks a Button. MultiplicationTable() displays the results of multiplying the integer by each of the numbers 2 through 10.
C++ Write a program that asks user for a positive integer side length. If they enter an illegal value, they must be prompted to enter a good one until they do. It then displays, using asterisks, a filled diamond of the given side length. For example, if the side length is 4, the program should display:
