I\'m trying to call a method in MacRuby that\'s defined like this: NSPropertyListSerialization ---------------------------
I have two questions: Q1. The character pointers are used to point to a location where a given string is stored. If we keep reassigning the string, does it lead to memory leak?
The two code examples below both add a node at t开发者_JS百科he top of a linked list. But whereas the first code example uses a double pointer the second code example uses a single pointer
template <typename T> inline T const& max (T const& a, T const& b) { return a < b ? b : a;
I created ptr as pointer to an array of 5 chars. char (*ptr)[5]; assigned it the address of a char array.
Consider the following code: int a[25][80]; a[0][1234] = 56; int* p = &a[0][0]; p[1234] = 56; Does th开发者_如何学Ce second line invoke undefined behavior? How about the fourth line?Both lines
I would like to create arrays of void pointers. # include <stdio.h> # include <stdlib.h> # include <unistd.h>
This is a piece of code that tries to build a linked list. struct node { char name[20]; int age; int height;
#include <stdio.h> int main (){ int x=10,*a=&x; int *b=(int *)&a; printf(\"%d%d%d%d%d%d\",x,a,*a,b,*b,**b);
I read in a C book that for an array num[7] the term num is equivalent to &num[0]. This concept was working fine for me but when I wrote this program shown below I again got confused.
