What are the string limits for the Standard Template Library in C++?
687
While an individual quoted string cannot be longer than 2048 bytes, a string literal of roughly 65535 bytes can be constructed by concatenating strings.
The capacity of a string reflects how much memory the string allocated to hold its contents. This value is measured in string characters, excluding the NULL terminator. For example, a string with capacity 8 could hold 8 characters. Returns the number of characters a string can hold without reallocation.
There is no official limit on the size of a string. The software will ask your system for memory and, as long as it gets it, it will be able to add characters to your string.
#include <iostream>

int main() {
std::cout << std::string().max_size() << std::endl;
return 0;
