To prevent memory leakage, use Valgrind in Linux to check general Linux technology-Linux programming and kernel information. The following is a detailed description. One of the most troublesome problems in C/C ++ development is memory management. Sometimes it takes several days to find a memory leak or a memory access out of bounds, if there is a tool that can help us do this, valgrind is such a tool.
