And the cpp switch statement terminates after that. The default Keyword In C++ Switch Case The default keyword inside the body of switch statement in C++ designates a code to execute if the value of the expression and any of the case constants do not match. However, the default case is an...
是否可以在"if condition"中使用多个案例来访问同一个函数 我需要为所有情况访问相同的函数,所以我在if条件中实现了多个case.作为IDE为此引发错误,显然这是错误的实现.但是有什么东西可以替代这种逻辑. java的 void movie() { int m; System.out.println("Choose the movie :"); System.out.println("1.BAHU...
expressionin eachcaselabel is converted to a constant value that's the same type ascondition. Then, it's compared withconditionfor equality. Control passes to the first statement after thecaseconstant-expressionvalue that matches the value ofcondition. The resulting behavior is shown in the ...
Thebreakstatement in C and C++ is used to stop a loop from iterating if the required condition is met within the code blocks of theswitchstatement. If thebreakstatement is not used, the program will continue to execute until the end of theswitchstatement is reached. ...
When we have manyif-elsestatements, the compiler must check all of them until a valid match is found. While inswitch-casestatements are used if we only want a certain block of code to run, if a certain condition is met. The following example checks a character if it is an alphabet or...

直接匹配字符串是不行的,C++ 中 case 只可以匹配a constant expression of the same type as the type of condition after conversions and integral promotions,所以在这里我需要把字符串转换为一个字面值整数从而进行 case 匹配。 将字符串转换为数字可以使用 HASH (Wikipedia - hash function) 方式来计算,在这里...
