Question

Is there any already implemented function that has initialArray, sizeOfInitialArray, outArray, and sizeOfOutArray parameters, takes one array and removes specific element, after it creates new array of the exact-element size, something like this below:

void removeElement(int *initialArray, int sizeOfInitialArray, int *& outArray, int & sizeOfOutArray)
 {
       // some code here
 }

I know I remember there was some function exactly processing the code as I want, buy I forgot the name of that function.

Thanks in advance for your efforts.

Answer 1

please see remove from stl..it will process inplace then you may create a new array and return back..

NotTested! complete code will be

#include <algorithm>
void removeElement(int *initialArray, int sizeOfInitialArray, int ValueToBeRemoved, int      *& outArray, int & sizeOfOutArray)
{
 int* endOfArray = initialArray+sizeOfInitialArray;
 endOfArray = remove(initialArray,endOfArray,ValueToBeRemoved);
 sizeOfOutArray = (endOfArray - initialArray);
 outArray = new int[sizeOfOutArray];
 memcpy(outArray,initialArray,(endOfArray - initialArray)*sizeof(int));
}
