In a ssignment statment the value on left of the equal sign is always equal to value of the right? Why ?

With assignment statment we assign the value of the right expreisson to the variable on the left of the '=' sign. thus, this mean that the value of the left side is always equal to that of the right side.

tip: to avoid misassignment when comparing values (using ==) with functions I write my if statements backwards to that of the usual convention to avoid misassignment of data because a missing = example normal ( can be a hard to find error ) a = 5; int SomeFunction(); if(a == SomeFunction()) { // misassignment because of missing = // if(a = SomeFunction()) // do magics } safe way ( misassignment will detected at compile) if(SomeFunction() == a) { // if(SomeFunction() = a) // do magics } note: this method won't help when just comparing two local variables (such as two ints or two chars) as both are usually writable. I feel it is a useful thing to do. (I have been caught out by this and it was very frustrating to find that I had simply missed an = sign in my haste). others may disagree but thems the breaks I guess.
