Bitwise OR of C LanguageSymbol: ^ returns an exclusive bitwise OR. Rule: The same is zero, and the difference is one. For example, only one number appears in a group of data. All other numbers are paired. Find this number. (Using bitwise operations)

The most powerful of C language-pointerPointers are inseparable from addresses. When we mention pointers, we should think of addresses, because in C language, the value of pointer variables is an address. With this value, it can point to the memory
