Question

suppose I declare a dynamic array like

int *dynArray = new int [1]; 

which is initialized with an unknown amount of int values at some point.

How would I iterate till the end of my array of unknown size?

Also, if it read a blank space would its corresponding position in the array end up junked?

Copying Input From users post below:

Thing is:

a) I’m not allowed to use STL (means: no )

b) I want to decompose a string into its characters and store them. So far I wanted to use a function like this:

 string breakLine (string line){            int lineSize = line.size();           const char *aux;           aux=line.data();           int index=0;            while (index<=lineSize){          mySynonyms[index]=aux[index];            index++;          } 

I thought that the array aux would end up junked if there was a large blank space between the two numbers to be stored (apparently not). And I was wondering if there was a way to iterate till an undefined end in this type of array. Thanks for you answers.

No portable way of doing this. Either pass the size together with the array, or, better, use a standard container such as std::vector
