Basic interger reverse c++ help?

Question

include <iostream>

using namespace std;

int main()

{

int x[10];

int i;

cout << "Type in your 10 numbers" << endl;

for (i=0; i<10; i++)

cin >> x[i];

while (x != 0)

++i;

--i;

cout << endl;

cout << "The Numbers reversed are:" << endl << endl;

while (x != 0)

{

cout << x;

--i;

}

cout << x;

cout << endl;

return 0;

}

What's wrong with my program it will not Display the reverse intergers.? Please Help

Answer 1

There are a few errors. These two lines

while (x != 0)

++i;

will just cause an infinite loop. You declared x as an array. So x !=0 is always true. Incrementing i does not change this. So remove these two lines

Also this bit

while (x != 0)

{

cout &lt;&lt; x;

--i;

}

cout &lt;&lt; x;

makes no sense. You declared x as an array so you must address it as x[i]

I think you want to change this bit to

while (i != 0)

    {

        cout &lt;&lt; x[i];

        --i;

    }

cout &lt;&lt; x[0];

Then it should work

Answer 2

if you are forced to use both FOR-loop and WHILE-loop:

#include &lt;iostream&gt;

using namespace std;

int main()

{

int x[10];

int i;

cout &lt;&lt; &quot;Type in your 10 numbers&quot; &lt;&lt; endl;

for (i=0; i&lt;10; i++)

cin &gt;&gt; x[i];

cout &lt;&lt; endl &lt;&lt; &quot;The Numbers reversed are:&quot; &lt;&lt; endl &lt;&lt; endl;

while (i &gt; 0)

{

cout &lt;&lt; x[--i];

}

cout &lt;&lt; endl;

return 0;

}

&gt;&gt;&gt;&gt;&gt;&gt;&gt;&gt;&gt;&gt; OR &lt;&lt;&lt;&lt;&lt;&lt;&lt;&lt;&lt;&lt;&lt;&lt;

if you are free to choose which loops to use:

#include &lt;iostream&gt;

using namespace std;

const int ENTRIES = 10; //use constants!

int main()

{

int x[ENTRIES];

cout &lt;&lt; &quot;Type in your 10 numbers&quot; &lt;&lt; endl;

for (int i = 0; i &lt; ENTRIES; i++)

cin &gt;&gt; x[i];

cout &lt;&lt; endl &lt;&lt; &quot;The Numbers reversed are:&quot; &lt;&lt; endl &lt;&lt; endl;

for(int i = ENTRIES - 1; i &gt;= 0; i--)

cout &lt;&lt; x[i];

cout &lt;&lt; endl &lt;&lt; endl;

return 0;

}

Answer 3

&quot;while (x != 0)

++i;

--i;&quot;

what is that for???

&quot;while (x != 0)

{

cout &lt;&lt; x;

--i;

}

cout &lt;&lt; x;&quot;

and that???

for (i=9; i&gt;=0; i--)

cout &lt;&lt; x[i];

will display the numbers reversed.
