I am getting confused with
for(i = 0; i < some_size; i++)
According to the 1999 ISO C standard (C99),
size_tis an unsigned integer type of at least 16 bit (see sections 7.17 and 7.18.3).
size_tis an unsigned data type defined by several C/C++ standards, e.g. the C99 ISO/IEC 9899 standard, that is defined in
stddef.h.1 It can be further imported by inclusion of
stdlib.has this file internally sub includes
This type is used to represent the size of an object. Library functions that take or return sizes expect them to be of type or have the return type of
size_t. Further, the most frequently used compiler-based operator sizeof should evaluate to a constant value that is compatible with
As an implication,
size_t is a type guaranteed to hold any array index.
