The problem with the code sprintf(s, "the %s jumped over the %s", "jaguar")
lies in incorrect format specifier usage, specifically a mismatch between the number of format specifiers and arguments.
"the %s jumped over the %s"
requires 2 string arguments (due to two %s
placeholders)."jaguar"
) is provided.sprintf
will read invalid/garbage values from memory (the "second" argument is missing).Provide the required number of arguments:
sprintf(s, "the %s jumped over the %s", "jaguar", "fence");
-Wall -Werror
to catch these issues during compilation.snprintf
to prevent buffer overflows:snprintf(s, sizeof(s), "the %s jumped over the %s", "jaguar", "fence");
clang-tidy
or cppcheck
to detect format-string mismatches.This error is a common pitfall in C/C++ and highlights the importance of careful format-string handling.
