Else if

Question

Is there a diffrence betwen else if or just else

Answer 1

An else if block runs if it fulfills another condition, but didn't fulfill any previous if statement; an else block runs no matter what if no other if or else if block is executed.
For example:
if(x==1)
y=1;
else if(x==2)
y=4;
else
y=0;
Let's assume that an integer x is already defined somewhere else. If x is one, then it fulfills the first if statement, and y is set to one. If x is two, then the first condition is not met, but the second one is; y is therefore set to 4. If x is any other number, then neither of the if statements are true, so y is set to zero.
