# misc-string-integer-assignment

The check finds assignments of an integer to `std::basic_string<CharT>` (`std::string`, `std::wstring`, etc.). The source of the problem is the following assignment operator of `std::basic_string<CharT>`:

    basic_string& operator=( CharT ch );

Numeric types can be implicitly casted to character types.

    std::string s;
    int x = 5965;
    s = 6;
    s = x;

Use the appropriate conversion functions or character literals.

    std::string s;
    int x = 5965;
    s = '6';
    s = std::to_string(x);

In order to suppress false positives, use an explicit cast.

    std::string s;
    s = static_cast<char>(6);
