About if & if else statement

[abtahi tajwar]

What is the dffrense between

  if{

&

 else if{

???

[YFGHNG]

They're branching statements that are usually seen together. Only difference is, you can declare if statements all by their lonesome, whereas with else if, you need a previously declared if.

In terms of pseudocode, it goes like

if this condition happens
    do this
else if another condition happens
    do that
else // for literally any other case that might happen that's not covered by the previous statements
    do another thing

Technically else if is not a separate construch, but just another if in the else statement:

YFGHNG example is parsed as:

if this condition happens {
    do this
} else { 
    if another condition happens {
        do that
    } else { // for literally any other case that might happen that's not covered by the previous statements
        do another thing
    }
}
