How Do We Declare Float Pointer at Roy Mahan blog

How Do We Declare Float Pointer. Let us declare our first. Float var = 3.1415, * ptr; Int * ptr1 = & x ; Pointers (pointer variables) are special variables that are used to store addresses rather than values. // p is a pointer to float // pp is a pointer to a pointer to float int (* fp) (int); As for the question in your title, pointers of type int* and float* are of different types. An int* should point to an int object; A float pointer only stores an address of a float variable. Let's go through an example: To declare and initialize a pointer to a pointer, you need to add an extra asterisk (*) compared to a regular pointer. Once you got basics of memory addresses, reference and dereference operator. Float * p, ** pp; // fp is a pointer to function with type int(int) Similarly need to declare b as float pointer if needs to contain the address of float variable. Value at address contained in b is an integer.
