An existence check before reading a file can catch and/or prevent a fatal error, for instance. For that reason, most programming language libraries contain a means of checking whether a file exists. An existence check can sometimes involve a " brute force " approach of checking all records for a given identifier, as in this Microsoft Excel ...
Ada C, C++ — — — — — Uses abstract interpretation to detect and prove the absence of certain run time errors and dead code in source code as well as used to check all MISRA (2004, 2012) rules (directives, non directives).

Ada Semantic Interphase Specification under the ISO/IEC 8652 Ada 95 Reference Manual (Ada Language Referencing Manual, 1994) is defined as an interface amidst an Aria environment and other tools requiring information from the Aria environment. Features of ASIS based tools could include: [4] high quality code analysis; automated code monitors ...
Ada is designed for developing very large software systems. Ada packages can be compiled separately. Ada package specifications (the package interface) can also be compiled separately without the implementation to check for consistency. This makes it possible to detect problems early during the design phase, before implementation starts.

Ada is a strongly typed language where all pointers are typed and only safe type conversions are permitted. All pointers are by default initialized to null, and any attempt to access data through a null pointer causes an exception to be raised. Pointers in Ada are called access types.
In terms of general software verification, this means that although one cannot algorithmically check whether any given program satisfies a given specification, one can require programs to be annotated with extra information that proves the program is correct, or to be written in a particular restricted form that makes the verification possible ...
But make sure to check local store hours before heading out. The last national day of mourning was in December 2018 in honor of the late former President George H.W. Bush, who died at 94.
