c++ program to compute quotient and remainder

C++ Program to Compute Quotient and Remainder

#include 
using namespace std;

int main()
{    
    int divisor, dividend, quotient, remainder;

    cout << "Enter dividend: ";
    cin >> dividend;

    cout << "Enter divisor: ";
    cin >> divisor;

    quotient = dividend / divisor;
    remainder = dividend % divisor;

    cout << "Quotient = " << quotient << endl;
    cout << "Remainder = " << remainder;

    return 0;
}

Output

Enter dividend : 22
Enter divisor : 4
Quotient : 5
Remainder : 2

c program to check given number is armstrong number or not

C program to check given number is armstrong number or not   

• A Positive number is called Armstrong number.  

abcd.... = an + bn + cn + dn +

• In this case of Armstrong number of 3 digits, the sum cubes of each digits is equal to the number of itself.

123 = 1*1*1 + 2*2*2 + 3*3*3

#include 
int main() 
{
    int num, originalNum, remainder, result = 0; // Integer values
    printf("Enter a three-digit integer: "); // Enter by user three digits
    scanf("%d", &num); // storing values
    originalNum = num; // replace number

    while (originalNum != 0) // while loop
    {
        // remainder contains the last digit
        remainder = originalNum % 10;
        
        result += remainder * remainder * remainder;
        
        // removing last digit from the orignal number
        originalNum /= 10;
    }

    if (result == num) // if else
        printf("%d is an Armstrong number.", num);
    else
        printf("%d is not an Armstrong number.", num);

    return 0;
}

Output

Enter three integer 371
371 is an Armstrong number

c program to calculate power of a number

C program to calculate power of a number

• The program takes two integer from user and then calculate power.

          For example : 2 pow 3 .

• In case 2 is base number and 3 is exponent number.  (2*2*2)

#include 
int main() 
{
    int base, exp; // integer values 
    long long result = 1; // constant values
    printf("Enter a base number: "); // User enter 
    scanf("%d", &base); //storing values
    printf("Enter an exponent: "); // User enter 
    scanf("%d", &exp); // storing values

    while (exp != 0) // while loop
    {
        result = result * base;
        --exp;
    }
    printf("Answer = %lld", result); // finalize result
    return 0;
}

Output

Ente a base number 3
Enter exponent number 4
Answer = 81

c program to check whether a number is palindrome or not using while loop

C program to check whether a number is palindrome or not using while loop

• An integer is palindrome if the reverse of that number is equal to the original number.

#include 
int main() 
{
    int n, reversedN = 0, remainder, originalN;
    printf("Enter an integer: ");
    scanf("%d", &n);
    originalN = n;

    // reversed integer is stored in reversedN
    while (n != 0) 
 
    {
        remainder = n % 10;
        reversedN = reversedN * 10 + remainder;
        n /= 10;
    }

    // palindrome if orignalN and reversedN are equal
    if (originalN == reversedN)
        printf("%d is a palindrome.", originalN);
    else
        printf("%d is not a palindrome.", originalN);

    return 0;
}

Output

Enter an integer = 1001
1001 is palindrome
