Visual studio 代码调试

  1. 跟踪变量，一步一步执行

F9: 在鼠标当前位置设置breakpoint。
F5：开始debug。在菜单栏中点击degug -> Windows -> autos。如此便可以看到每个变量的值随着调试的过程动态改变。
选中code中变量，右键->add watch: 将这个变量放入跟踪中。
Continue按钮：开始执行，到下一个breakpoint
F10: 不同与continue，这个是一句一句执行，可以跟踪临时变量。但是这回跳过子函数。
F11：一句一句执行，回进入子函数。

  1. run without debugging

ctrl+F5
