Question

input: 8732
desired output: 2378

not sure why it isn't printing the value backwards, if you couldgive me a hand that would be good.

#include <cstdlib>
#include <iostream>
using namespace std;

/**
* Prototypes
*/
bool invert(int &n);

/**
* This program will read a positive integer number, invert itand print
* the new number.
*/
int main(int argc, char *argv[])
{
   // Variables declaration
   int num;
  
   // Get a value for n
   cout << "Enter an integer number (n>0):";
   cin >> num;

   // Invert the number and print the result

    invert(num);
    if (num<=0){
    cout << "Invalid number."<<endl;}
    else{
    cout << "The number "inverted" is: "<< num << endl;}

    system("PAUSE");
}




bool invert(int &n)
{
   int inv = 0, dig;
    if (n<=0){
    return false;}
    else{
   for (inv;inv<n;inv++){
       for(inv=n-1;inv>=0;inv--)
    return true;}
}}

Explanation / Answer

please rate - thanks note- I moved the call to invert #include #include using namespace std; /** * Prototypes */ void invert(int &n); /** * This program will read a positive integer number, invert itand print * the new number. */ int main(int argc, char *argv[]) {     // Variables declaration     int num;        // Get a value for n     cout > num;     // Invert the number and print the result        if (num
