Mention The Levels Of Pointers Can You Have? |
|
Answer» The ANSWER depends on what you mean by “levels of pointers.” If you mean “How many levels of indirection can you have in a single declaration?” the answer is “At LEAST 12.” int i = 0; int *ip01 = & i; int **ip02 = & ip01; int ***ip03 = & ip02; int ****ip04 = & ip03; int *****ip05 = & ip04; int ******ip06 = & ip05; int *******ip07 = & ip06; int ********ip08 = & ip07; int *********ip09 = & ip08; int **********ip10 = & ip09; int ***********ip11 = & ip10; int ************ip12 = & ip11; ************ip12 = 1; /* i = 1 */The ANSI C standard says all compilers MUST handle at least 12 levels. Your compiler might support more.
