In this article, we discussed three ways to build a simple calculator: If-else statements, switch-case statements, and function pointers(or Lambdas). The function pointer method is more flexible and results in cleaner, easier-to-maintain code. Each approach has its own strengths, with function...

In a basic calculator program, users can choose an operation by entering a number, and the program responds accordingly: int choice; printf("Select operation:n1. Additionn2. Subtractionn3. Multiplicationn4. Divisionn"); scanf("%d", &choice); switch (choice) { case 1: // Perform addition ...

当然还有其他的类型也支持for-range,如string类型,其是字符元素序列的集合。 另外,可以使用auto自动推断range元素的数据类型。 for (auto c : str) cout << "[" << c << "]"; 跳转表达式 break,常用于跳出本级循环,或者用于switch-case-break表达式中。 // break loop example #include <iostream> using ...
