C# Question
C# else if confusion
I am currently studying the conditional constructions. Correct me if I am wrong but else if and else(if(){}) is the same thing... Example:
a=5;
if(a==6)
{
Console.WriteLine("Variable 'a' is 6");
}
else if(a==5)
{
Console.WriteLine("Variable 'a' is 5");
}
And
a=5;
if(a==6)
{
Console.WriteLine("Variable 'a' is 6");
}
else
{
if(a==5)
{
Console.WriteLine("Variable 'a' is 5");
}
}
Are these things the same? And if yes why does else if exist if I can write it the "second way"(the second example that I wrote)?

Yes, these are effectively identical.
The reason the "else if" statement exists is to make cleaner code when there are many conditions to test for. For example:
if (a==b) {
//blah
} else if (a==c) {
//blah
} else if (a==d) {
//blah
} else if (a==e) {
//blah
}
is much cleaner than the nested approach
if (a==b) {
//blah
} else {
if (a==c) {
//blah
} else {
if (a==d) {
//blah
} else {
if (a==e) {
//blah
}
}
}
}
