incrementing all array elements at a time by 1

I don't know why you are searching for a built in function to do this as only 2 lines of code will get the desired code.Look how it could be done:

int[] myArray = {1,2,3,4,5};
int temp=0;

for(int i=0; i<myArray.length; i++)
{
    temp = myArray[i]+1;
    myArray[i] = temp;
}
//your array value was changed above,now see exactly it works or not!
for(int k=0; k < myArray.length; k++)
System.out.println(myArray[k]);

Output:
2,3,4,5,6

Hope that will help you.

In C++ you can use the class std::valarray. It is similar to std::vector, but defines a number of standard operators that modify each element individually. check out http://www.cplusplus.com/reference/valarray/valarray/operators/[^] as a reference; it also includes some example code.

For incrementing an array you could write e. g.:

#include <valarray>     // std::valarray

void foo ()
{
  int myarray[]= {10,20,30,40};

  std::valarray<int> bar (myarray, 4);  //  10 20 30 40

  bar += 1; // 11 21 31 41
}

P.S.:
A word of warning if you use this class in Windows: some standard windows header file #defines the macros min() and max(), which will nuke the functions std::valarray::min() and std::valarray::max() if included before you include valarray. You can prevent this in various manners:
1. use #undef to kill these definitions
2. use #define NOMINMAX before including the windows headers to prevent their definition
3. #include valarray first

(Just one of the many reasons why I hate #define !)

You will need to loop (a for loop[^] will be suitable for that) to get this done. Therefore you can't do that in that way.

Probably you are more interested in a linked list[^], where you will be able to add or remove nodes easily.

Hope this helps. :thumbsup:
