Using std::map

This example demonstrates how to use a map to store key-value pairs.

cppCopy code#include <iostream>
#include <map>
#include <string>

int main() {
std::map&lt;std::string, int&gt; ageMap;

// Inserting key-value pairs
ageMap&#91;"Alice"] = 30;
ageMap&#91;"Bob"] = 25;
ageMap&#91;"Charlie"] = 35;
// Accessing and displaying elements
for (const auto&amp; pair : ageMap) {
    std::cout &lt;&lt; pair.first &lt;&lt; " is " &lt;&lt; pair.second &lt;&lt; " years old." &lt;&lt; std::endl;
}

return 0;
}
