What

• A single group of objects all the same type.
• Array indexes start at 0 and go to array count minus 1.

• Syntax:

      type name[CONSTANT INT];
  

• Examples:

      char foo[24];         /* Array of chars */
      char bar[5], *ptr;      /* The [] doesn't carry either! */
  

• The size of an array does not need to be known.
• There is NO bound checking for arrays.
• Syntax:

      extern type name[];
  

• Only static or global arrays are implicitly pre initialized. This is just like other static or global variables.
• static and global array elements initialized to the default for their type, usually this is 0 or NULL
• A Static Array may be defined without a size if it is pre initialized.
• All of the following declarations are the same:

      int a[4] = { 3, 2, 1, 0 };
      int a[4] = { 3, 2, 1 };
      int a[] = { 3, 2, 1, 0 };
  

• New operator [ ]

      int a[4];
  
      a[3] = 10;
      for (i = 0; i < 4; i++) {
          a[i] = i;
      }
