C++ int array max size
WebYou are given an array a a of length n n, and an integer x x. You can perform the following operation as many times as you would like (possibly zero): replace two adjacent elements of the array by their sum. Websize_t can store the maximum size of a theoretically possible object of any type (including array). size_t is commonly used for array indexing and loop counting. Programs that use other types, such as unsigned int , for array indexing may fail on, e.g. 64-bit systems when the index exceeds UINT_MAX or if it relies on 32-bit modular arithmetic.
