Analyze Dynamic Dispatch with dlopen and dlsym

Write a C program that loads a library dynamically and documents how to trace these calls during reverse engineering.

Requirements:

• Use dlopen to load a shared library (e.g., libc or libm)
• Use dlsym to resolve a function address by name
• Call the resolved function
• Document how to trace dlopen/dlsym calls with debuggers and ltrace
• Explain how malware uses these functions to hide imports
• Output must contain the keywords the test cases expect

Success Criteria:

• Code compiles with gcc -Wall -Wextra -ldl
• Output contains the expected substrings for each test case
