A programming language specification describes the syntax and semantics of a programming language. In some instances, the values of a term may be unspecified. In C, the value of an uninitialized variable is unspecified. In some cases, the value will be the “contents of [the] memory… [occupying] those addresses.” A C program was used to generate 32,768 uninitialized bytes. The program was compiled with Apple clang 12.0.5 on a MacBookPro (2018) running macOS 11.4.0. These uninitialized bytes were then interpreted as grayscale image data and layed atop other images.
