<\/span><\/h3>\nThe indexing operator [] provides a simple and straightforward way to access values in a map.<\/p>\n
To access a value using the indexing operator, we need to provide the key for which we want to retrieve the associated value. The operator returns the value associated with the given key, and if the key doesn’t exist in the map, it inserts a new key-value pair with the default value for that data type. <\/p>\n
“`cpp
\nstd::map myMap;<\/p>\n\/\/ Adding key-value pairs to the map
\nmyMap[1] = “John”;
\nmyMap[2] = “Jane”;
\nmyMap[3] = “Alice”;<\/p>\n
\/\/ Accessing values using the indexing operator
\nstd::string name = myMap[1]; \/\/ Accessing the value associated with key 1
\n“`
\n**The value associated with a key can be accessed using the indexing operator, myMap[key].**<\/p>\n
