The character represented by ch is first converted to unsigned char and then copies it into the first … WebWe use memset () to set all values as 0 or -1 for integral data types. It will not work if we use it to set as other values. The reason is simple, memset works byte by byte. That's why your initialization with INT_MAX is wrong here.
