Memory Map Questions and Answers
A memory map in C language represents how memory is allocated and organized for variables, functions, and data segments during program execution. It includes the text (code), data, heap, and stack segments. Understanding the C memory map is vital for programmers tackling programming questions and answers in competitive coding tests or technical interviews by companies like TCS, Infosys, and Wipro. These questions assess your grasp of runtime memory allocation, pointers, and scope of variables. This section includes detailed C language questions with answers on memory maps, helping learners debug programs efficiently and develop optimized code.
