 ## Remarks
 
-Supplying too few arguments to a format function leads to undefined behavior, because the function attempts to read values that were never passed. Possible consequences include incorrect output, crashes, or even security vulnerabilities such as information leaks. To ensure stability and safety, always match the number and types of arguments to the format specifiers in the string.

 ## Example
 
-The following code generates this warning because it uses an incorrect number of arguments in the call to `sprintf_s` and the missing argument is an integer. If the unsafe function `sprintf` was used instead of the safer variant `sprintf_s`, this code would likely cause a stack overflow instead of just an unexpected output:
