what is the difference in this pointers decalarition ?

int *ptr[10];

and

int (*ptr)[10];

[relient]

One is an array of pointers while the other is a pointer to an array.
Example:

int *ptr[10];
int var1, var2;
ptr[0] = &var1;
ptr[1] = &var2;

......

int (*ptr)[10];
int multiDimensiona lArray[5][10];

ptr = multiDimensiona lArray;

[code break]

Thank you relient

so how i can access array (multiDimension alArray) with pointer( ptr ).

[relient]

The same way you would with the multiDimensiona lArray variable.

ptr[0][1] = 5;

int *ptr[10] refers to a ptr is an arrary of 10 pointers to an integer.

whereas int (*ptr)[10] refers to a ptr is a pointer to an array of 10
integers.
