Static and dynamic analysis

In addition to testing for warnings, libraries should also be tested with static and dynamic analysis tools. Once again, as an author of a library, you must assume your users might use static and dynamic analysis tools to shore up the quality of their own applications. If your library triggers these tools, your users are more likely to look for alternatives that have been tested more thoroughly.

For C++, there is a large number of tools that can be used to analyze your libraries. In this recipe, we will focus on Clang Tidy and Valgrind, which are both free to use. Let's look at the following simple example:

#include <iostream>int universe(){    auto i = new int;    int the_answer;    return the_answer;}int main(){ std::cout ...
