else
printf("NOT TEN");
a = 100;
}
The above code looks perfectly normal. If a is 10, then print "TEN" otherwise print "NOT TEN" and set a to 100.
With certain languages (C/C++ and Java included), that code would not quite work as described. The way the code is indented can make someone believe that it is doing something else.
According to the way C/C++ and Java would interpret the above code, it should look more like this:
void doStuff(int a) {
if(a == 10) {
printf("TEN");
}else {
printf("NOT TEN");
}
a = 100;
}
Which means that no matter what, a would be set to 100 at the end of the function call, which is not how the indentation made it look in the original example.
Keep in mind that both examples are identical in function if interpreted by a C/C++ or Java style compiler.
It can be either
if (cond1) { if (cond2) stmt1; else stmt2; }
or
if (cond1) { if (cond2) stmt1; } else stmt2;
It is important to rembember that the compiler does not know which of those you meant, so it choose the first interpretation: the dangling else belongs to the inner if.
Nothing, but be careful with the dangling else's: if (cond1) if (cond2) stmt1; else stmt2; means: if (cond1) { if (cond2) stmt1; else stmt2; } not this: if (cond1) { if (cond2) stmt1; } else stmt2;
Here is an example:if (exp1) if (exp2) stmt1 else stmt2It could mean different things, like:if (exp1) { if (exp2) stmt1 else stmt2 }if (exp1) { if (exp2) stmt1 } else stmt2;if (exp1) { if (exp2) stmt1 else stmt2 } else stmt2Well, the first is the good answer, but it can be confusing, so when in doubt use {brackets}
This could lead to a memory leak
The pointer that points to a block of memory that does not exist is called a dazzling pointer or wild pointer
Dangling references and garbage, otherwise known as memory leaks, can occur in the same application and programming language. These symptoms are evidence of sloppy memory management by the programmer.Dangling references and garbage collection cannot normally occur at the same time, as the garbage collector is not supposed to discard an item so long as there are still any references to it. Therefore, a reference can never "dangle" (i.e. refer to a no longer existing item).
The dangling else problem occurs when an if-else construct is ambiguous, and it is unclear which if statement should be associated with the else statement. This can lead to unintended behavior in the code if not handled properly. It is recommended to use braces to explicitly define the scope of if-else blocks to avoid this issue.

Nothing, but be careful with the dangling else's: if (cond1) if (cond2) stmt1; else stmt2; means: if (cond1) { if (cond2) stmt1; else stmt2; } not this: if (cond1) { if (cond2) stmt1; } else stmt2;
