| **Query** | **Tags** | **Purpose** |
|-----------------------------|-----------|--------------------------------------------------------------------|
| Call to alloca in a loop (`cpp/alloca-in-loop`) | reliability, correctness, external/cwe/cwe-770 | Finds calls to `alloca` in loops, which can lead to stack overflow if the number of iterations is large. Newly displayed on [LGTM](https://lgtm.com/rules/1508831665988/). |
| Call to function with fewer arguments than declared parameters (`cpp/too-few-arguments`) | correctness, maintainability, security | Finds all cases where the number of arguments is fewer than the number of parameters of the function, provided the function is also properly declared/defined elsewhere. Results are displayed by default on [LGTM](https://lgtm.com/rules/1508860726279/). |
| Call to a function with one or more incompatible arguments (`cpp/mismatched-function-arguments`) | correctness, maintainability | Finds all cases where the types of arguments do not match the types of parameters of the function, provided the function is also properly declared/defined elsewhere. Results are not displayed by default on [LGTM](https://lgtm.com/rules/1508849286093/). |

| Call to a function with one or more incompatible arguments (`cpp/mistyped-function-arguments`) | correctness, maintainability | Finds all cases where the types of arguments do not match the types of parameters of the function, provided the function is also properly declared/defined elsewhere. Results are not displayed by default [on LGTM](https://lgtm.com/rules/1508849286093/). |
| Use of dangerous function (`cpp/dangerous-function-overflow`) | reliability, security, external/cwe/cwe-242 | Finds calls to `gets`, which does not guard against buffer overflow. These results were previously detected by the `cpp/potentially-dangerous-function` query. Results for both queries are displayed by default on LGTM. |
