I passed a variable to switch, the value of the variable is 2 so the control jumped to the case 2, However there are no such statements in the above program which could break the flow after the execution of case 2. That’s the reason after case 2, all the subsequent cases and defaul...

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[]) ...
In the following program, we use switch case statement to implement calculator. We read two numbers and a choice of operation from user. Based on the selected operation, the corresponding case block is executed. C Program </> Copy #include<stdio.h>voidmain(){inta;printf("Enter number, a ...

In Figure 4, 'switchval' (0) will first be compared to the constant in the first case statement (0). Since 'switchval' is equal to 0, the code on line 14 will execute and output 'code path executed for value 0'. Next, the 'break' statement on line 15 causes program to exit th...
