需要判断的条件很少时,一般不超过5个 使用switch-case: 能用则用 参考资料 Advantage of switch over if-else statementIf…else…if vs switch…case, difference and usage?switch vs if else
A switch case statement is more readable compared to if-else statements. In the end, the choice is yours and I hope this blog helps lead you in the right path to making the most informed decision when to use an if-else statement verses a switch case!
switch语句和if else if 语句的区别 一般情况下,它们两个语句可以相互替换 switch...case语句通常处理case为比较确定值的情况,而if...else...语句更加灵活,常用于范围判断(大于或等于某个范围) switch语句进行条件判断后直接执行到程序的条件语句,效率更高。而 if 语句几种条件,就得判断多少次 条件判断 ...
float constant cannot be used in the switch as well as in the case. You can not use the variable expression in case. You cannot use the same constant in two different cases. We cannot use the relational expression in case. Difference between switch case and if-else ...
if (N >= 2 && N <= 5) { printf("N is between 2 and 5"); } else { printf("N is outside the range of 2 & 5"); } switch(N) { case 2: case 3: case 4: case 5: printf ("N is between 2 and 5"); break;
When it comes to code footprint, an if-else ladder can be written in less number of lines than a switch block. We don’t have to use break and default in case of an if-else block. However, we find that the if-else statement block is repetitive whereas the switch block is sequential...
If not, explain why. Assume that n and digit are int variables. a) switch (n = 2) case 0: cout "Draw." end1; break; case 1: cout "Wi What is a conditional operator in C? What is a conditional operator in Java? What is the difference between for loops and while l...
The main difference is that switch despatches immediately to the case concerned, typically via an indexed jump, rather than having to evaluate all the conditions that would be required in an if-else chain, which means that code at the end of the chain is reached more slowly than code at ...
case 2: somethingElse = something; break; // is not flagged and is valid } return somethingElse Anonymous November 15, 2004 The comment has been removed Anonymous November 15, 2004 Ah.. I forgot to mention: IF fallthrough would have been an option for switch then my analogy breaks. ...
In text-based languages, you may be familiar with the if, if-else, or switch statements; LabVIEW’s equivalent structures are the Select structure for simple if statements and the Case Structure when having more input choices is necessary like an if-else or switch statement. Like their text-...
