C-Command Line Arguments Questions and Answers
Command line arguments in C allow passing values to a program at runtime through the main() function parameters argc and argv. This feature is essential for flexible and interactive program execution. Many programming questions and answers in coding interviews test this concept through practical applications and debugging scenarios. This section provides C command line argument questions with answers and explanations, helping learners strengthen their understanding of runtime input handling. These examples are useful for TCS, Tech Mahindra, and Wipro placement exams where efficiency and clarity of coding are tested.
