How do i change my merge algorithm to accept different arguments in c++? -

the original code wrote uses these arguments:

int m = size of sorted list 1

int n = size of sorted list 2

int a[] = sorted list 1

int b[] = sorted list 2

int c[] = merged list of 1 , 2

i asked add code existing file uses these different arguments:

intvectorit start1

intvectorit end1

intvectorit start2

intvectorit end2

intvectorit start3

these variables defined here (n size of first sorted array, m size of second sorted array):

typedef vector<int> intvector;  typedef intvector::iterator intvectorit;  intvector vector1(n); intvectorit start1,end1,it1; start1 = vector1.begin(); end1 = vector1.end();  intvector vector2(m); intvectorit start2,end2,it2; start2 = vector2.begin(); end2 = vector2.end();  intvector vector3(n+m); intvectorit start3,end3,it3; start3 = vector3.begin(); end3 = vector3.end();  //--the variables version of merge intvector myvector(n+m); intvectorit mystart,myend,myit; mystart = myvector.begin(); myend = myvector.end(); 

my merge code:

void mymerge(int m, int n, int a[], int b[], int c[]) {   int i, j, k = 0;    while (i < m && j < n)   {         if (a[i] <= b[j])         {               c[k] = a[i];               i++;         }          else         {               c[k] = b[j];               j++;         }          k++;   }    if (i < m)   {         (int p = i; p < m; p++)         {               c[k] = a[p];               k++;         }   }     else   {         (int p = j; p < n; p++)         {               c[k] = b[p];               k++;         }    }  } 

if me figure out how take iterators arguments, me out ton. thank in advance.

since sounds homework, won't write whole solution. however, here suggestions on migrating mymerge:

change signature to

void mymerge(     intvectorit astart,     intvectorit aend,     intvectorit bstart,      intvectorit bend,     intvectorit cstart,      intvectorit cend     ); 

change running indices iterators, e.g.

intvectorit = astart; 

change loop stopping condition use iterators, e.g.

i != aend
