Points to follow for reading the code:

1) * – read as pointer to
2) [] – read as array of
3) () – read as function returning
4) Start reading from the variable name
5) Read the right first without going over the parenthesis
6) Then go left without going over the other parenthesis.
7) Start inwards and move outwards.
9) Reading is from right to left.

char *ptr <\/em><\/strong>: ptr is a pointer to char type

int **ptr<\/strong><\/em>:<\/em><\/strong>\u00a0 ptr is a pointer to a pointer to int type

int (*ptr)[5]<\/strong>: ptr is a pointer to array of size 5 where each element is of int type.

char *ptr[5]<\/strong>: ptr is an array of size 5 where each element points to pointer to character type.

char *(*ptr)[5]<\/strong>: ptr is a pointer to array of size 5 where each element is a pointer to char type

void *fun()<\/strong>: fun is a function returning a pointer to void.

int (*fun)()<\/strong>: fun is a pointer to function returning int type.

int *(*ptr)()[]<\/strong>: ptr is a pointer to function returning an array of pointer to integers

int (*(*ptr[])())(void)<\/strong> – ptr is array of pointer to function returning pointer to int that takes no parameters

char (*(*var())[])()<\/strong>: var is a function returning a pointer to an array of pointer to function returning char.

int *(*(**fun [][5])())[]<\/strong>: fun is an array[5] of pointer to pointer to function returning pointer to array of pointer to int

float (*(*ptr[5])())(void (*)(char, char *))<\/strong>: ptr is an array of size 5 where each element is a function pointer that takes no parameter and returns a pointer to function that takes two parameters and returns float<\/p>\n","protected":false},"excerpt":{"rendered":"

When reading code, follow these points: 1) * – pointer to 2) [] – array of 3) () – function returning 4) Start at the variable name 5) Read right first without crossing parenthesis 6) Then go left without crossing 7) Start inwards and move outwards. Reading is right to left.
