Storage space layout of C programs under Linux

programmer applies for allocation and release. The heap is growing from a low address bit to a high address bit, using a chained storage structure. Frequent malloc/free cause a discontinuity in memory space, resulting in fragmentation. When applying for heap space, the library function searches for a sufficient amount of space available in accordance with a certain algorithm. So the heap is much less efficient than the stack.The source file that will
