Full array of strings

From "The point of the sword"

The topic requirements are simple, output a string of full array, for example: input ABC output Abc/acb/bac/bca/cba/cab

Code I really do not see how to understand, perhaps this is the recursive program is more difficult to debug the reason for it.

voidPermutation (Char*PSTR,Char*Pbegin) {    if(*pbegin==' /') {cout<<pstr<<Endl; }    Else    {         for(Char*pch=pbegin;*pch!=' /';p ch++)        {            Chartemp=*pCh; *pch=*Pbegin; *pbegin=temp; Permutation (Pstr,pbegin+1); Temp=*pCh; *pch=*Pbegin; *pbegin=temp; }    }}voidPermutation (Char*pstr) {    if(pstr==NULL)return; Permutation (PSTR,PSTR);}
