Python 下的 return 关键字 def make_sum(a, b): return ('+', a, b) >> make_sum(1, 2) ('+', 1, 2) 显示地返回一个元组(tuple),当然 return 关键字返回多个用逗号隔开的内容时,会自动把它们组合为元组类型(tuple)。 代码解读 def make_sum(a, b): return '+', a, b >> make_sum(...
there is an upper limit for the number of elements in any tuple. This is set by the number of template arguments in the template definition. To make the code sections short, the limit of four elements is used here. It is, however, straightforward...
Most directly, you can return a tuple or pair, e.g., given auto f(int a, int b) { return std::make_tuple(a, b); } Since C++11: 12 int a, b; std::tie(a, b) = f(1, 2); Since C++17: auto [a, b] = f(1, 2); // destructuring declaration http://en.cppreference...
std::tuple<int, int> va_static_cast(); %ignore va_static_cast(); #pragma SWIG nowarn=SWIGWARN_CPP14_AUTO %inline %{ #include <tuple> auto va_static_cast() { return std::make_tuple(0, 0); } However I couldn't find a way to make it work for class methods, e.g. consider:...
: IsSuccess(isSuccess), Message(message), ErrorCode(errorCode), Content(std::make_tuple(content...)) { } private: /// @brief 不关注Content /// @param message /// @param errorCode QICResult(constQString& message,interrorCode) : IsSuccess(false), Message(message), ErrorCode(errorCode) ...
返回多个值:在函数中可以使用"return"语句返回多个值,这些值会被封装成一个元组(tuple)返回。例如: 代码语言:txt 复制 def get_user_info(): name = "John" age = 25 gender = "Male" return name, age, gender user_info = get_user_info() print(user_info) # 输出:('John', 25, 'Male') 在...
defmake_sum(a, b):return('+', a, b) >> make_sum(1,2) ('+',1,2) 显示地返回一个元组(tuple),当然 return 关键字返回多个用逗号隔开的内容时,会自动把它们组合为元组类型(tuple)。 defmake_sum(a, b):return'+', a, b >> make_sum(1,2) ('+',1,2) ...
在下面的函数中,return函数用于返回函数的执行结果或者返回指定的值。 具体来说,return函数会将其后的表达式的值作为函数的返回值,并结束函数的执行。当函数执行到return语句时,会立即停止执行函数内的代码,并将return后的值返回给调用者。 return函数的作用包括: 返回函数的执行结果:可以通过return语句将函数的计...
For this, we usetie()function, which unpacks the tuple. Below is the example of using tuple in C++. #include <bits/stdc++.h>usingnamespacestd;intmain() {//define a tuple of <roll,marks,name>tuple<int,int, string>student;//create the pairstudent=make_tuple(1,80,"XYZ");//extract...
但是这个返回值可以是一个结构体或者是一个类,而结构体和类中可以容纳很多信息.
