Note: #define macros are evil in 4 different ways: evil#1, evil#2, evil#3, and evil#4. But they're still useful sometimes. Feel ashamed, feel guilty, but when an evil construct like a macro improves your software, use it.

Classism. We consider arrays ''second class objects''. They don't vote, and they get treated as pointers. Additionally, they're merely objects, not citizens. Marx wrote about this a lot. [a]

The array is the conductive transfer unit of the direct current into the water which generates the ionic field and hence transfers the energy into the body.

Normally I dislike #define macros, but you should use them with pointers to members because they improve the readability and writability of that sort of code.) I strongly recommend these features. In the real world, member function invocations are a lot more complex than the simple example just given, and the difference in readability and writability is significant. comp.lang.

The function of the plates on the Array is to produce the complex field that interacts directly with the water, and through the water is translated to bio electric energy, that is then carried by the water to our bodies. The array plates are composed of copper and of a proprietary non-reactive alloy.

Usually, you don't want to. When people speak casually of a pointer to an array, they usually mean a pointer to its first element. Instead of a pointer to an array, consider using a pointer to one of the array's elements. Arrays of type T decay into pointers to type T (see question 6.3), which is convenient; subscripting or incrementing the resultant pointer will access the individual members of the array.

An array is not a pointer, nor vice versa. An array reference (that is, any mention of an array in a value context), turns into a pointer (see questions 6.2 and 6.3). There's hardly such a thing as an array (it is, after all, a ''second-class citizen''); the subscripting operator [] is in fact a pointer operator. a higher level of abstraction, a pointer to a block of memory is effectively the same as an array (though this says nothing about other uses of pointers).

Part of the ANSI conspiracy to restrict people to passing pointers; this was undertaken after the first discovery that passing large arrays recursively could cause crashes. Since then, with the passing of MS-DOS, it has become a non-issue; since all serious machines have virtual memory, you can pass as much data as you want on the stack without detectable problems. [a]

It is the programmer's responsibility to make sure your recursion code have a exit point!!! See the following code (borrowed from above question), no compiling errors, no linking errors, but the program will never print out the "after". struct Node { int num; Node *next; Node() { next = new Node(); //Infinite recursion!!! } }; int main() { printf("before\n"); Node a; //run out of memory, soon be dead! printf("after\n"); }

My compiler complained when I passed a two-dimensional array to a function expecting a pointer to a pointer. The rule by which arrays decay into pointers is not applied recursively. An array of arrays (i.e. a two-dimensional array in C) decays into a pointer to an array, not a pointer to a pointer.

conversion specifier would you use with printf( ) to formaqt an integer as a double? Write down the full syntax required to convert the integer 33.

Your hints about dynamic creation of arrays work fine for one-dimensional arrays. But I need a global matrix. There is no problem if the matrix is small. But, if I simply put int A[200][100] = {{}}; I will increase the size of my program by about 40K (200*100*sizeof(int)). This is really unacceptable. Obviously, I need to create a matrix dinamically. But I have no any idea how to do this. Very good question. Solving this problem requires good knowledge about how arrays and pointers are related.

array object is created with the java::new command. To create an int[5] array with values 11 through 15, you would enter: set arrayObj [java::new {int[]} 5 {11 12 99 14 15}] $arrayObj set 2 13 Note that in the above example the array type is passed with brackets around it.
