Question

im simple asking if this is ok. i was asked to do the following. Write a program that will continuously ask the user for positive integers (until the
user enters a negative integer at which the program will be terminated). Every
time the user inputs a positive integer the program will print out this integer in
reverse. Your program should have a function that accepts and integer and returns
an integer in reverse. To convert the integer to its reverse, your program will call
this function. at the end of each output i keep getting 0. please explain why. also if i use void main with the function i get garbage. please explain why. thanks in advance

this is my code….

#include<iostream>
#include<cstdlib>

using namespace std;

int reverseNum(int num){
    for(int j=num; j>0; j--)
        cout<<j<<" ";
        cout<<endl;
    return false;
}

int main(){
    double enternum = 0;

    do{
        cout<<"Enter a positive number > 0, to begin countdown ";
        cin >>enternum; 
        cout<<reverseNum(enternum);
        cout<<endl;
    }
    while(enternum>0);

    if(enternum<=0)
        cout<<"Invalid entry, good bye.";
    cout<<endl;

    return 0;
}

Answer 1

because of this: return false; – I’ll leave it to you to figure out the rest..
