Can I get event of modification into unordered_map or not
Refer code below: https://code.sololearn.com/c98nzq9fCQ9L I have an unordered_map of string and int. I am using  operator each time as I need to modify value of existing element [as mentioned in function multiply]. What I need is to stop processing modification of existing value like umap["Eleven"] = -1; These type of statements are so many in code and can't check each and every such statements. This statement is just an example that I dont want few elements to be updated with certain values. Can I get some event which will be fired when umap["Eleven"] = -1; are called on unordered_map object? Feel free to ask for clarification in case of any query or confusion. Thanks in advance...!
Then you could overload the  function of the unordered map class. You can search up multiple tutorials on how to do this. Such as this https://stackoverflow.com/questions/21064979/c-specialization-of-operator-in-unordered-map
You can use an if statement and the find method to check whether or not the value exist. Like this: if(map.find(“Eleven”) != map.end)
It won't work for me as code base is very large and can't do find and update for all entries simillar to below : umap["Elevan"] = -1;
