char is actually integer, even so they are represented with letters. Anyway, yes you can use the controlling expression of type char in switch statements.
If you have a loop in your switch statement or around your switch statement, you can use the continue statement in that. You cannot use a continue statement outside of a loop (do, for, or while).
There are two programming languages which use a C switch statement. The two languages are C and C++, hence the name C switch statement. There may be more, but those are the most obvious ones
scanf is a function, not a statement. Example: int a; char name[12]; scanf ("%d %s", &a, &name[0]);
Ends the case statement. Without it, any code after where the break; is supposed to be will get executed as well until it does encounter a break; or the end of the switch.Code Example:char cTest = 'a';switch(cTest) {case 'a':/* Code here gets executed. */case 'b': //* Code here gets executed. */case 'c':/* Code here gets executed. */break;case 'd':/* Code here won't be executed. */default:/* Code here won't be executed. */}

But of course.
we can use switch statement in multiple time but in if statement we can not use multiple time

The break statement is frequently used to terminate the processing of a particular case within a switch statement. Lack of an enclosing iterative or switch statement generates an error.Within nested statements, the break statement terminates only the do, for, switch, or whilestatement that immediately encloses it. You can use a returnor goto statement to transfer control elsewhere out of the nested structure.This example illustrates the break statement:#include int main() { char c; for(;;) { printf_s( "\nPress any key, Q to quit: " ); // Convert to character value scanf_s("%c", &c); if (c == 'Q') break; } } // Loop exits only when 'Q' is pressed

In java, a switch statement is used to simplify a long list of 'if' statements. A switch statement takes the form of:switch (variableName){case condition1; command1;case condition2; command2;...}
There is not switch called "if". We generally use "if" statement in batch programming in DOS.
Ends the case statement. Without it, any code after where the break; is supposed to be will get executed as well until it does encounter a break; or the end of the switch.Code Example:char cTest = 'a';switch(cTest) {case 'a':/* Code here gets executed. */case 'b': //* Code here gets executed. */case 'c':/* Code here gets executed. */break;case 'd':/* Code here won't be executed. */default:/* Code here won't be executed. */}
If you must evaluate two or more expressions separately, use multiple if statements. If you only need to test all the possible evaluations of a single expression, use a switch.
Switch statements in Java can only use integer values. This means that we can switch on char values (because chars are simply ints with a different output type), but we can not switch on Strings or any other objects. The following examples are both valid in Java. // switch 1 int x = 1; switch(x) { case 0: break; case 1: break; default: break; } // switch 2 char x = '1'; switch(x) { case '0': break; case '1': break; default: break; }
