Pointer Rules in C programming language.Here is the list of c programming pointer rules, these points must be remembered while you are working on pointers to avoid compilation and run time errors.Few rules about C pointers 1) A pointer variable does not store value directly just like int, fl...
C語言沒有字串型別,而是用char array來模擬字串,由於本質是array,所以可以用pointer來表示字串,也因如此,造成C語言在操作字串時含其他語言差異甚大。 1/* 2(C) OOMusou 2007http://oomusou.cnblogs.com 3 4Filename : C_string.c 5Compiler : Visual C++ 8.0 / BCB 6.0 / gcc 3.4.2 / ISO C++ 6...
If you do need to have a pointer to"c"(in the above example), it will be a "pointer to a pointer to a pointer" and may be declared as − int***d=&c; Mostly, double pointers are used to refer to a two−dimensional array or an array of strings. ...

In the above code, we took three pointers pointing to three strings. Then we declared an array that can contain three pointers. We assigned the pointers ‘p1’, ‘p2’ and ‘p3’ to the 0,1 and 2 index of array. Let’s see the output : ...
Pointers to char are oftenused to represent strings. To represent a valid byte string, a pointer must be pointing at a char that is an element of an array of char, and there must be a char with the value zero at some index greater or equal to the index of the element referenced by...

In the C function pointer is usedto resolve the run time-binding. A function pointer is a pointer that stores the address of the function and invokes the function whenever required. Where function pointers are used in real time? Function Pointer are pointers i.e. variable, which point to th...
