What is wrong with the following code?

Question

if(int j<=10);
n=n+j;

Answer 1

● if(j <=10)
n+=j; //n=n+j;
//not necessary to use { } , if only 1 statement to execute if if() condition evaluates to true.

Answer 2

; means statement ended
Should be { after if (...)

Answer 3

Well not sue what language you're talking about since you used a lot of tags but:
Make sure to initialize the variables before using them for example in C#:
int n = 0;
int j = 10;

if(j <= 10)
{
n += j; //this is the same as n = n + j;
}

You're not able to initialize the variable inside a statement like "if" you can however do it in a for loop and don't end the statement with a ";" you just have open and close a bracket;

ruby:

n = 0
j = 10

if j <= 10
n += j //same as n = n + j
end

java is like the C# example;
If you're using any IDE it will tell you what's wrong.
Hope this helps!
