this is how i did!! and it works too!!! but my professor doesnt want me to define a specific number like 5 i did in the program!!! and he doesnt want me to use the std library too!!!how can i make the user input any size of the number user wants!!!and he wants me to do using own algorithm and use swap and other methods!! help me if u can !!! #include #include #include #define s 5 using namespace std; int main () { cout >per[i]; } int size = sizeof per/sizeof(int); (per,per+size); do { for (int i=0; i<size; i++) { cout << per[i] << " "; } cout<<endl; } while ( next_permutation (per,per+size) ); return 0; }

&nbsp;you can use dynamic memory allocation using &quot;new&quot;

To dynamically allocate an array: &nbsp; int n; printf(&quot;Kati euta number: &quot;); scanf(&quot;%d&quot;, &amp;n); &nbsp; &nbsp; int * arr = (int *) malloc(n * sizeof(int)); for(int i=0;i&lt;n;i++) { printf(&quot;\nNumber %d halnus: &quot;,i+1); scanf(&quot;%d&quot;,&amp;arr[i]); } &nbsp; for(int i=0;i&lt;n;i++) { printf(&quot;%d\t&quot;,arr[i]); } &nbsp; free(arr); Your Prof. might want you to swap the elements in the array (in place). See&nbsp;http://www.cplusplus.com/refer... details on this function. Good luck!
