The switch case in the C language is used when we have more than one option for the single variable that we need to execute. The switch finds the best match for the switch expression and executes the statement accordingly. If we don’t find any match at all for the switch expression, t...
int c = 20; switch ( a ) { case b: // Code break; case c: // Code break; default: // Code break; }The default case is optional, but it is wise to include it as it handles any unexpected cases. Switch statements serves as a simple way to write long if statements when the ...

Example of Switch Case in C Let’s take a simple example to understand the working of a switch case statement in C program. #include<stdio.h>intmain(){intnum=2;switch(num+2){case1:printf("Case1: Value is: %d",num);case2:printf("Case1: Value is: %d",num);case3:printf("Case1...
case 1: break; default: break; } 1. 2. 3. 4. 5. 6. 不过要注意,一旦加上了大括号,在case 0后面便不能访问到变量b了。 注意,如果上述代码以C方式进行编译,编译结果则会有所不同: main.c #include <stdio.h> #include<stdlib.h> int main(int argc, char *argv[]) ...
switch case用法详解：1、switch是“开关”的意思，它也是一种“选择”语句，但它的用法非常简单。2、switch是多分支选择语句。说得通俗点，多分支就是多个if。从功能上说，switch语句和if语句完全可以相互取代。但从编程的角度，它们又各有各的特点，所以至今为止也不能说谁可以完全取代谁。3、当嵌套...
