While declaring Pointer for an Integer value, we assign a
default size i.e 4 byte of memory for the Integer variable.
But in the case of char by default it assigns 1 byte of
memory for that character variable.

The type of declaration is the same for both.

Char a[5], *p; // for char variable
int *i; // for Int variable
