For example, in VB this sort of thing would be perfectly legal (Im using C syntax to illustrate): int val 15 string valString valI realize that C requires a constant. My question is, why give the VB guys the "option" of creating a dynamic switch/select case but not give it to the C guys? switch case in c is a control statement which contains various cases and executes them on the basis of comparison matched.Use break clause to exit from switch case. Programming Example.int option switch statement in C - Learn C programming in simple and easy steps starting from basic to advanced concepts with examples including C Overview, language basics, Environment Setup, ProgramEach value is called a case, and the variable being switched on is checked for each switch case. C Switch Examples. Following examples show switch statement. You can debug examples online.
int i 1 switch (i) case 1: case 2: Console.WriteLine("One or Two") break default: Console.WriteLine("Other") break Demonstrate C switch statement and examples.Switch statement evaluates the value of an expression and try to find a match in a list of case constants.class Program . static void Main(string args) . int test 2 Currently the switch statement is case-sensitive. It would be nice to be able to specify the StringComparison to use for switching on strings.The following C program shows how to int values work with SwitchCase statement. int i 5 switch (i) . case(1): case(2): Console.WriteLine(i)In C Its illegal to fall through to another case label if the case label is followed by one or more statements.See Compiler Error CS0163 for an example. Fortunately this still lets you do what the OP originally wanted, which is this Since int comparison is very slightly faster than string comparison.
