std::basic_string::max_size is used to compute the maximum number of elements the string is able to hold due to system or library implementation limitations.
size_type max_size() const; Parameters : None Return value : Maximum number of characters Exceptions : None
// CPP program to compute the limit of a string // using max_size #include <iostream> #include <string> int main()
{ std::string str;
// Calling max_size()
std::cout << "Maximum size of a string is " << str.max_size() << std :: endl;
} |
Output:
Maximum size of a string is 4294967294
Note : The maximum size can depend on the compiler and system.
