WebMar 15, 2024 · Setting the initial value of an object to zero is called zero initialization. Syntax : static T object; Tt = {} ; T {} ; char array [n] = " "; Zero initialization is performed in the following situations:-. Zero is initialized for every named variable with static or thread-local storage duration that is not subject to constant initialization ... Webint foo = 0; auto bar = foo; Here, bar is declared as having an auto type; therefore, the type of bar is the type of the value used to initialize it: in this case it uses the type of foo, which is int. Variables that are not initialized can also make use of …
WebApr 11, 2024 · Your long int is likely a signed 32-bit integer type, which means the largest positive integer it can store is 2,147,483,647, but your sum adds up to 5,000,000,015. Because this is larger, integer overflow has occurred. Replace the long int type with long long int. Or to make the sizes of the types more explicit, include and use int64_t.
