Are there any better methods to do permutation of string?

Question

void permute(string elems, int mid, int end)
{
    static int count;
    if (mid == end) {
        cout << ++count << \" : \" << elems << end         


        

Answer 1

This is not the best logic, but then, i am a beginner. I'll be quite happy and obliged if anyone gives me suggestions on this code

#include
#include
#include
int c=1,j=1;


int fact(int p,int l)
{
int f=1;
for(j=1;j<=l;j++)
{
f=f*j;
if(f==p)
return 1;

}
return 0;
}


void rev(char *a,int q)
{
int l=strlen(a);
int m=l-q;
char t;
for(int x=m,y=0;x>a;
int f=1;

for(int o=1;o<=strlen(a);o++)
f=f*o;

perm(a,f,0);
getch();
}
