Can someone Explain please.!?

Question

while giving a challenge i got this question and it seems bit hard to me

the code is:

string x="";
string y"sololearn";
x+=y.substring(8,1);
x+=y.substring(5,3);
console.write(x);

Ans : near (how?)

Answer 1

i dont c#.

but
y.substring(8,1) = n
y.substring(5,3) = ear

Answer 2

Syntax of substring is-

stringName.substring(index from, length of substring);

Jay has described the rest

Answer 3

step through the code, use break points, and output in between answers.

+= stands for x = x + ...
in the first line x is empty. The result of the substring is 'n'. That makes the x = 'n'
in the second line x = 'n' and the result of the substring is 'ear'. Which makes the finale result. 'n' + 'ear' = 'near'.
