Answer:

The following C++ program will assign the number 34.5678 to a variable named number. It will display number rounded to the nearest integer value and then will display number rounded to two decimal places.

#include <iostream>

#include <cmath>

using namespace std;

int main()

{

double number = 34.4576 ;

  int i = int(number+0.5);

/* round() is used to round off the given digit  and returns the nearest integral value to provided parameter in round function. */

       int j = round(number);

  cout << i << endl;

  cout << j << endl;

/* ceil() function returns the smallest integer which is greater than the given integer and will round up to the nearest integer. */

       float b = ceil(number * 100.0) / 100.0;

       cout << b;

       return 0;

}
