Understanding Pointers in C Pointers are special variables that store the address of other variables, unlike regular variables which hold values like integers or floats. They belong to derived data types and their declaration involves specifying a base type (e.g., int, float) followed by an asterisk (*) and pointer name. The base type indicates the data type of the variable whose address is stored by the pointer but does not define its own datatype as integer or float.
Declaring and Initializing Pointers To declare pointers correctly, use syntax such as 'int *p' where p will point to an integer-type variable's memory location. Initialization assigns it using '&variable_name', ensuring compatibility between declared types; for example assigning 'float *ptr = &b;' requires b’s datatype be float too otherwise errors occur during execution.
