   Change depends on the language you use. The subscripts of C/C++/JAVA/C# are all starting from 0. Your array is available

   0~99999, 100000 available, but generally The string will be followed by ‘\0’ as the terminator, so there should be one less

   you can only use the array as 100000, and when used as a string, you can only use 99999

   can be implemented by the following statement:
   char *p; //Define pointer variable
   p = (char *)malloc(100000);//Apply space and assign value Give p.
   Parsing:
   malloc is a memory allocation function, which is defined as
   void * malloc(size_t size);
   The function is to apply the size of the memory size and return the assigned address value.
   And the character type, each element occupies 1 byte space, so the total space of 100000 variables is 100000 bytes, so the parameter size is 100000.

   Look at the array type you define, if it is int, lint, folat, etc.
