I am a trainer of a starting C programming class. A few of my college students use Macs for his or her growth. I like to recommend to them to make use of Xcode with clang and lldb, because it has the perfect help on their platform. (On different platforms I like to recommend Eclipse and gcc, since gcc has higher help for the C language than Microsoft’s compiler.) Since we’re introducing pointers as a part of the course, it might be helpful to have a software like valgrind’s memcheck that may test for using uninitialized reminiscence. Is there such a software that can be utilized with Xcode? The sanitizer instruments referred by https://developer.apple.com/documentation/xcode/diagnosing-memory-thread-and-crash-issues-early do not explicitly point out checking for using uninitialized values.
