详解C++编程中数组的基本用法

// using_arrays.cpp
int main() {
 char chArray[10];
 char *pch = chArray; // Evaluates to a pointer to the first element.
 char ch = chArray[0]; // Evaluates to the value of the first element.
 ch = chArray[3]; // Evaluates to the value of the fourth element.
}

// using_arrays_2.cpp
// compile with: /EHsc /W1
#include <iostream>
using namespace std;
int main() {
 double multi[4][4][3]; // Declare the array.
 double (*p2multi)[3];
 double (*p1multi);

 cout << multi[3][2][2] << "\n"; // C4700 Use three subscripts.
 p2multi = multi[3];    // Make p2multi point to
          // fourth "plane" of multi.
 p1multi = multi[3][2];   // Make p1multi point to
          // fourth plane, third row
          // of multi.
}

// initializing_arrays1.cpp
class Point
{
public:
 Point() // Default constructor.
 {
 }
 Point( int, int ) // Construct from two ints
 {
 }
};

// An array of Point objects can be declared as follows:
Point aPoint[3] = {
 Point( 3, 3 )  // Use int, int constructor.
};

int main()
{
}

// initializing_arrays2.cpp
class WindowColors
{
public:
 static const char *rgszWindowPartList[7];
};

const char *WindowColors::rgszWindowPartList[7] = {
 "Active Title Bar", "Inactive Title Bar", "Title Bar Text",
 "Menu Bar", "Menu Bar Text", "Window Background", "Frame" };
int main()
{
}

char szError1[] = "Error: Disk drive not ready.";
char *psz = szError1;

szError1 = psz;
