size_type max_size() const;
Parameters : None
Return value : Maximum number of characters
Exceptions : None

CPP

// 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.
