Question

write a program to print the sum and average of all the palindromic numbers from 2 to 2000 in c++​

Answer 1

Answer:

Here's a program in C++ to print the sum and average of all the palindromic numbers from 2 to 2000:

```

#include <iostream>

using namespace std;

int main() {

int sum = 0;

int count = 0;

for (int i = 2; i <= 2000; i++) {

int num = i;

int rev = 0;

while (num > 0) {

int digit = num % 10;

rev = rev * 10 + digit;

num = num / 10;

}

if (rev == i) {

sum += i;

count++;

}

}

float average = (float) sum / count;

cout << "Sum of palindromic numbers from 2 to 2000: " << sum << endl;

cout << "Average of palindromic numbers from 2 to 2000: " << average << endl;

return 0;

}

```

This program uses a for loop to iterate through all the numbers from 2 to 2000. For each number, it checks if it is a palindrome by reversing the digits of the number and comparing it to the original number. If it is a palindrome, it adds it to the sum and increments the count. Finally, it calculates the average by dividing the sum by the count and prints both the sum and average.
