C++, pointers, exception thrown: read access violation. this was 0xFFFFFFFFFFFFFF5F - c++

Question

I am working on a school project that is all about pointers. I have been setting variables that string just fine but when I arrived at an int it throws
Exception thrown: read access violation. this was 0xFFFFFFFFFFFFFF5F
I am not sure what this particular variable age is a problem and the rest were fine.
I tried to set int age = 0; to initialize it somehow but no success. Here is the screenshot and the files if that helps narrow down the issue.
