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 << "Input "< int per[s];

for (int i=0; i {
cin>>per[i];
}
int size = sizeof per/sizeof(int);

(per,per+size);

do {
for (int i=0; i {
cout << per[i] << " ";
}
cout< } while ( next_permutation (per,per+size) );
return 0;
}

 you can use dynamic memory allocation using "new"

To dynamically allocate an array:
 
int n;
printf("Kati euta number: ");
scanf("%d", &n);
 
 
int * arr = (int *) malloc(n * sizeof(int));
for(int i=0;i<n;i++)
{
printf("\nNumber %d halnus: ",i+1);
scanf("%d",&arr[i]);
}
 
for(int i=0;i<n;i++)
{
printf("%d\t",arr[i]);
}
 
free(arr);

Your Prof. might want you to swap the elements in the array (in place). See http://www.cplusplus.com/reference/algorithm/swap/ for details on this function.
Good luck!
