HereNULLis a special pointer which will define pointer is not pointing to anything. But it may cause run time error so be careful while doing this. int*ptr=NULL; 5) If you want to initialize two pointers with same memory address (reference), you can make assignment operation (=) to the...

测试是代码开发工具箱的核心组成部分。通过使用单元和集成测试进行自动化测试,不仅可以帮助开发者在早期检测功能回归,还可以作为新加入项目的开发者的起点。它可以帮助新开发者提交代码变更,并确保预期的功能得以保留。对于代码的用户来说,自动化测试在验证安装是否保留
