Erasing an Array member in C

[hefty1985]

Hi Guys,

I think I put the question in the wrong format in the previous time .I am trying to eliminate certain elements off an array or vector in C without affecting other elements. Any idea of how this can be done neatly. For example:

Input Array : 8 7 6 5 **0** 9 **0** 8 7

Ouput Array: 8 7 6 5 9 8 7

Any idea how a C function can be written to execute such functionality. I am nit sure if C has STL erase( ) as in C++. Any idea of using erase and if so how would it work for the above example (no need to write full code just important bits).

Best regards,

Hefty

HI,
There is no readymade functions available to erase elements in an array.
What u have to do is traverse through the array and if u find the element in array is invalid then move the subsequent element to the current position.

I think You have to write a function of your own to carry out this task.

I suggest you my own way of doing it.

Have a function with parameters, the parameters should be Array's subscript
values.

Use a for Loop to prepone the values which are after the position mentioned.

For Ex:

void func1(int *arr, int pos1) // if you put more positions then assign default values so that it can work for lesser parameters also
{
  for(int j=pos1,k=pos1+1;arr[k]!='\0';j++,k++)
   {
        arr[j] = arr[k];
   }
        arr[j] = arr[k];
}
 

Confirm whether this is the one you are looking for...

Thanks this what I was after. But I could not understand what the last line of your code is doing !!!.
