Pointers Questions and Answers
Pointers questions with answers are a crucial part of C programming preparation, often included in technical interviews and MCQ-based exams. Pointers are variables that store the memory address of other variables, making them fundamental to dynamic memory management and efficient program design. These C programming MCQ questions and answers help students understand pointer arithmetic, function pointers, arrays, and memory allocation. Commonly asked in placement exams by TCS, Infosys, and Wipro, mastering pointer concepts gives you a competitive edge in coding tests and programming interviews.
