If that's what you really want to do, the compiler will allow it. It might indicate an inefficient design, though.
Yes, you can call a function from within a switch statement in C. switch (i) { case 0: function1(i); break; case 1: function2(i); break; default: function3(i); break; } When the function returns, you will still be in the switch statement.
Convenience here is in terms of the human reader of the program; a good optimizing compiler may treat both the switch and the nested if-else as pretty much the same thing. For me, using a switch is easier because it is easier to add additional cases to the switch. It can be (in my opinion) harder and more dangerous logically to fit additional test cases in a nested if. Finally, in some compilers the switch statement may be implemented in the hardware, so you end up with better performance.
A switch-case statement is used to select between multiple values for a single variable. Like having a case for 1 2 and 3 for an integer. An If-else statement is used for evaluating an expression to either true or false.
switch is a loop which is used for checking various conditions and print corresponding matter.switch(a)//where a is that whose condition you have to check.#includemain(){char a;printf("enter a char.");scanf("%c",&a);switch(a){case 'a':printf("vowel");break;case 'e':printf("vowel");break;case 'i':printf("vowel");break;case 'o':printf("vowel");break;case 'u':printf("vowel");break;default:printf("consonent");}}
Perhaps you meant 'switch statement' instead of 'a switch'?Something like this: -> -> switch () -> { } -> (empty) | -> []; -> | -> case: | default: -> | break;
UNIX has no bearing on the C language; it is cross-platform. There is no select/case in C, you probably meant switch/case. However, a switch/case is a conditional jump while a nested loop is a loop within a loop. Besides the C language they have nothing in common with each other.
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
If(condition) { if-else statement; } else { if-else statement; }
The switch / case statement.

In C a structure within a structure is called nested. For example, you can embed a while loop in another while loop or for loop in a for loop or an if statement in another if statement.
The break statement is used to exit a loop or switch-case.

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
