pointers are used in a way that is fundamentally distinct from the way in which we use “normal” variables, and we have to include an asterisk to tell the compiler that a variable should be treated as a pointer. Here are two examples of pointer declaration: ...
Here, type is the pointer's base type; it must be a valid C data type and var-name is the name of the pointer variable. The asterisk * used to declare a pointer is the same asterisk used for multiplication. However, in this statement the asterisk is being used to designate a variable...
The “&” (ampersand) operator is the address operator, using the ampersand will return the address of a variable. Print Address Code The “*” (asterisk) operator is a pointer to a variable. Compare Address’ Code Using pointers allows us to pass variables into functions, and then manipulat...

A pointer is a very powerful and sophisticated feature provided in the C language. A variable defined in a program the compiler allocates a space in the memory to store its value. The number of bytes allocated to the variable depends on its type. For ins
