How to determine the end of an integer array when manipulating with integer pointer?
- by AKN
Here is the code:
int myInt[] ={ 1, 2, 3, 4, 5 };
int *myIntPtr = &myInt[0];
while( *myIntPtr != NULL )
{
cout<<*myIntPtr<<endl;
myIntPtr++;
}
Output: 12345....<junks>..........
For Character array: (Since we have a NULL character at the end, no problem while iterating)
char myChar[] ={ 'A', 'B', 'C', 'D', 'E', '\0' };
char *myCharPtr = &myChar[0];
while( *myCharPtr != NULL )
{
cout<<*myCharPtr<<endl;
myCharPtr++;
}
Output: ABCDE
My question is since we say to add NULL character as end of the strings, we rule out such issues!
If in case, it is rule to add 0 to the end of integer array, we could have avoided this problem. What say?
