  • Last Updated : 21 Aug, 2018

The smatch::max_size() is a built-in function in C++ STL which returns the maximum number of elements in the match_results object that can be held by the smatch container.

Syntax:

smatch_name.max_size()

Parameters: This function does not accept any parameters.
Return value: This function returns the maximum number of elements that can fit into the smatch container.

Below programs illustrate the above function:

Program1:






// C++ program to illustrate the 
// smatch::max_size() function in C++ STL
// when data-type is char 
#include <bits/stdc++.h>
using namespace std; 
int main()
{
    // match_results object(smatch)
    match_results<char*> match;
  
    cout << "max_size: " << 
    match.max_size() << endl;
  
    return 0;
}
Output:
max_size: 768614336404564650

Program2:




// C++ program to illustrate the 
// smatch::max_size() function in C++ STL
// when data-type is int 
#include <bits/stdc++.h>
using namespace std; 
int main()
{
    // match_results object(smatch)
    match_results<int*> match;
  
    cout << "max_size: " << 
    match.max_size() << endl;
  
    return 0;
}
Output:
max_size: 768614336404564650
