Question

Write a program that prompts the user to input a decimal number and outputs the number rounded to the nearest integer.

Answer 1

// c++ program to find nearest integer of entered decimal point number
#include <iostream>
using namespace std;
int round(double value); // function prototypes
int main()
{
   double num;
   int intnum;
   cout << " Please enter number " ;
   cin >> num;
   // echo print the input
   cout << " The number entered: " << num ;

   // calculate and display the nearest integer for each number
   intnum = round(num);
   cout << " The nearest integer: " << intnum;
  
}
// function round will round a floating point value to its nearest integer value
int round(double value)
{
   return int(value + 0.5);
}
