Is there a technical difference between two logical operators?

I am not a programming student yet, this is purely for curiosity. I am wondering how is it possible that one logical operator can be quite different in a single programming language. I know you cannot mix use of AND and OR in the same boolean expression, however is there an actual technical difference between e.g. && and ||? Both seem to do the same job, but why have two distinct logical operators?

Is there some subtle differences between the two?

Thanks

They have similar semantics, but you cannot use them interchangeably.

&& is syntactic sugar for and:

if(a && b) c();

However, if you only have a||b in your code, the expression a||b evaluates to 1 (true). So you cannot use it as a substitute for &&.

You can, however, use it as a logical short cut to simplify the construction of an if statement:

if(a&&!b) c();

I've always considered both to be transparent and to make little difference.

Use whichever is most intuitive or is clearer to you.

It's all a question of style. If you have a bunch of &&s in a row, then consider moving those to more separate expressions to improve readability. That's just my opinion, you don't need to do that but I tend to do that anyway.
