编译后c(9) : error C2064: term does not evaluate to a function c(17) : error C2064: term does not evaluate to a function c(20) : error C2064: term does not evaluate to a function是在找不出问题啊相关知识点: 试题来源: 解析 主要是数据项过多,又由于数学习惯,产生问题,缺少符号.前两...
The following sample code long offset(long v) { if (!v) return 0; if (v > 0) return 1; if (v < 0) return -1; } produces warning: non-void function does not return a value in all control paths [-Wreturn-type] So does long offset(long v) {...
Thestd::invokefunction in the C++ standard library is usually used to call a functor with parameters. std::function<void(int)> func = ...; // same as func(42) std::invoke(func, 42); Whatstd::invokebrings to the table is that you can use it for other things beyond just functors....
