基本上是最近看了什么写什么repo

5.3 布尔值表示

cout<<"the expression x=100 has the value";

cout<<(x=100)<<endl;

cout<<"the expression x<3 has the value";

cout<<(x<3)<<endl; //输出0

cout.setf(ios_base::boolalpha);//该函数调用设置了一个标记,该标记命令显示true和false,而不是1和0

cout<<"the expression x<3 has the value";

cout<<(x<3)<<endl; //输出false
