What is difference between if else and switch statement in c plus plus?
Switch Case is used when you want to check whether a certain variable is equal to a set of particular values and theres a different task to do for each value. If-then-else is can be used to check for anything, including a range of values and perform a specific task if the condition is met. For eg: switch(c) { case(1): task1(); break; case(2): task2(); break; case(3): task3(); break; default: task9(); break; } if(c>=1 && c<=9) task1(); else task2(); Note: You cannot use >= or <= in switch case.
What is case select in c language?
It is switch-case. Example: switch (opsign) { case '+': . result = a + b; . break; case '-': . result = a - b; . break; ... default: . printf ("opsign=%c unknown\n", opsign); }
What is the function of visual c plus plus switch condition?
The switch / case statement.
Calling a function from switch in C?
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.
What is default in switch is C language?
When in the switch none of the case's is true, the code at the default: is executed.
What are decision making constructs in c?

What is difference between select Case statement and nested loop in c programming in UNIX?
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.
When might you omit a break statement from the end of a case in a switchstatement?
You can omit the break statement at the end of a case whenever you want execution to flow into the next case, or when the case is the last case. For instance, if you wanted to test a character regardless of whether it was upper or lower case, you might use the following: void f(char c) { switch (c) { case 'a': // execution flows into next case... case 'A': // do something break; case 'b': // execution flows into next case... case 'B': // do something else } }
What is break in c?
The break statement is used to exit a loop or switch-case.
What is regular grammar of a switch in C programming language?
Perhaps you meant 'switch statement' instead of 'a switch'?Something like this: -> -> switch () -> { } -> (empty) | -> []; -> | -> case: | default: -> | break;
What is A - B - C if the answer is -13?
There are an infinite number of combinations for A, B, and C in this case. Just assign any number for A and for B, then calculate the value for C.There are an infinite number of combinations for A, B, and C in this case.

What are labels in c language?
Labels in C are used for CASE statements and for GOTOs (many people forget that C has GOTOs). The syntax goes like this:if (some_condition) { goto MyGotoLabel; }......MyGotoLabel:......switch (MyVariable) {case 1:...break;case 2:...break;default:...}As you can see, both GOTO and CASE labels use a colon, which is a giveaway that they both really do the same thing. The switch/case statement is more structured than the goto, since it branches out from a single point and cannot go backwards and the range of where it can branch to is more clearly delineated, so it's a less-bad goto. But it's really still a goto.Note that, unlike most interpreted C-based languages, C can only use a constant integer value (or a preprocessor macro that evaluates to a constant integer value) for a case label.
