No, it is a function. But printf does return a value: the number of characters it has written.
Cannot be answered universally; it depends on the function.
Don't know; you haven't shown the function
Maximum.
Two possibilities: on success, it'll return the amount of characters printed. On failure, a negative number is returned.
An IF function can only return one value. Once it finds a value that fits its criteria it does not continue. It is important that you construct a IF function correctly, particularly if it is a nested IF function, so that you get the correct result. If you do that, then issues around where it stops calculating are not a problem. It is simple to construct a nested IF function in the wrong way and it is a mistake a lot of people make.
return;orreturn ;PS: not function, statement!
The return statement is used in functions to return control to the caller. If the function is declared non-void, the return statement also allows the programmer to return a value to the caller.
To test if two number are equal in JavaScript, we use the == operator and compare them. The below function test if two number (a and b) are equal. The function returns 1 if a is greater, -1 if b is greater, and 0 if the numbers are of equal value. function isEqualTo( a, b ){ if ( a > b ){ return 1; } if (b > a ){ return -1; } return 0; }
No. In Excel you would use the COUNT function to do it, or possibly the COUNTA or COUNTIF, depending on exactly what you were trying to do.
