memset function usage

The memset function usage includes initializing arrays, clearing strings, clearing buffers, setting specific values, etc. Detailed introduction: 1. Initialize the array, the syntax is "int arr[10];memset(arr, 0, sizeof(arr)); // Set all elements of the array arr to 0"; 2. Clear the string, illegal "char str[100];memset(str, '\0', sizeof(str)); // Clear the string str" and so on.
