Can you return multiple values from a function in C?
There are many approaches to this 'problem'. Since a C function is only allowed to return one value as the name of the function you have to provide parameters to the routine if you want multiple values to be returned.For example, traditionally you return a value thus:int Today () ;if (Today() == 2) ....int Today (){/* Some logic */return value ;}So if you want multiple values, send parameters to the routine that can be changed:int Today (int * val1, int * val2, char * charValue) ;Then, call it:int first ;int second ;char third ;if (Today (&first, &second, &third) == 2)In this case first, second, and third can be changed inside the Today routine and return multiple values.int Today (int * val1, int * val2, char * charValue){*val1 = 5 ;*val2 = 10 ;*charValue = 'Y' ;return 2 ;}
What is a return statement used for?
It means end the function. Functions automatically end when execution reaches the end of the function, but you can return from a function at any point within the function with a return statement. If the function returns a value to its caller, you must provide a reachable return statement along with the value you wish to return.
Write a program to return a function using class in C Plus Plus?
Classes cannot return values, only functions can return values. But you cannot return a function from a function, you can only return a function pointer -- a pointer variable holding the address of the function you wish to return. All possible return values must be of the same type, therefore all function signatures and return types must be exactly the same -- only the name of the functions can differ.
The set of all values that a function will return as outputs is called the of the function?
The set of all values that a function will return as outputs is called the *range* of the function.
What statement returns a value from a function?
return

What is the difference between return 0 and return -1 in c?
If we consider any function that is not the main function that is declared as "bool" i.e it will return boolean values to the main function-0 & 1, meaning 'false' and 'true' respectively. If we have to tell the main function that the condition checked in the function is false or disagreed, then we return 0 to the main function and when we have to tell that the condition checked in the main function is true or agreed, then we return 1 to the main function.
Where do you use no argument no return in c function?
Where there is no need to return any type of value from a function
What statement returns a value from a function?
return
How do you echo the return value of a function?
echo function();
Why is return statement not necessary when function is called by reference?
return is not necessary if the return type is void, and you want to leave the function only at its end.
