How can I erase an element of a unordered map with a string and vector in C++?

my unordered map looks like this:

unordered_map> umap;

my function looks like this:

void removeElemnt(string &strTmp, int &intTmp) { for (auto &it : umap) { for (int x = 0; x < it.second.size(); x++) { if (strTmp == it.first) { if (intTmp == it.second[x]) { // ERASE VECTOR ELEMENT HERE // } else { cout << "int does not exist" << endl; } } else { cout << "str does not exist" << endl; } } } }

it stores values like: name = [1,2,3]
