unordered_multimap max_size() function in C++ STL
The unordered_multimap::max_size() is a built-in function in C++ STL which returns the maximum number of elements that the unordered_multimap container can hold.
Syntax:
unordered_multimap_name.max_size()
Parameters: The function does not accepts any parameters.
Return Value: It returns an integral values which denotes the maximum size of elements that the container can hold.
Below programs illustrates the above function:
Program 1:
// C++ program to illustrate the // unordered_multimap::max_size() #include <bits/stdc++.h> using namespace std; int main() { // declaration unordered_multimap< int , int > sample1; // inserts key and element // in sample1 sample1.insert({ 10, 100 }); sample1.insert({ 50, 500 }); cout << "The max number of elements that sample1 can hold: " << sample1.size(); cout << "\nKey and Elements of Sample1 are:" ; for ( auto it = sample1.begin(); it != sample1.end(); it++) { cout << "{" << it->first << ", " << it->second << "} " ; } return 0; } |
Output:
The max number of elements that sample1 can hold: 2 Key and Elements of Sample1 are:{50, 500} {10, 100}
Program 2:
// C++ program to illustrate the // unordered_multimap::max_size() #include <bits/stdc++.h> using namespace std; int main() { // declaration unordered_multimap< char , char > sample1, sample2; // inserts key and element // in sample1 sample1.insert({ 'a' , 'A' }); sample1.insert({ 'g' , 'G' }); cout << "The max number of elements that sample1 can hold: " << sample1.size(); cout << "\nKey and Elements of Sample1 are:" ; for ( auto it = sample1.begin(); it != sample1.end(); it++) { cout << "{" << it->first << ", " << it->second << "} " ; } return 0; } |
Output:
The max number of elements that sample1 can hold: 2 Key and Elements of Sample1 are:{g, G} {a, A}
