Please can anyone help me differentiate between else if and if else in C. Or are they the same thing

Question

C Programming

Answer 1

Vector

There is no syntax like (if else) there is (else if)

Answer 2

Vector

Sometimes we can have nested if else like:

if (a > b) {
if ( a > c) {
//Print a
} else {
//Print c
}
} else {
if (b > c) {
//Print b
} else if (a > c) {
//Print a
} else {
//Print c
}
}

Answer 3

Understood. Many thanks

Answer 4

Some languages support three different keywords that are similar in form to if/elseif/else. But C only supports if/else. It does not formally recognize else if. Rather, when you use else if, the C compiler interprets it as an else clause that contains a nested if.

So when you write C code in the following style - which is perfectly accepable - it is interpreted as the syntax below it:

if ()
else if ()
else if ()
else

In reality is seen to be nested as:

if ()
else {
if ()
else {
if ()
else
}
}

In the final analysis they are the same!

Answer 5

U have to understand the principe of logical operators in mathematics , it 's the same AND OR NOT

Answer 6

If there are only yes and no situation
Then only if else

if(true)
//
else
//

If there are yes no maybe situation then

if ()
//
else if()
//
else
//

Answer 7

Thanks🙂

Answer 8

Thank you. But I can see if else being an actual thing. If there are say 3 possible situations. Can I say
If()
//
if else ()
//
else
//

Answer 9

Would it work the same way?

Answer 10

Vector

You can apply many else if based on situation like in calculator:

if (ch == '+') {

} else if (ch == '-') {

} else if (ch == '*') {

} else if (ch == '/') {

} else {
// Invalid input
}

Answer 11

I see. Thanks
