I'm getting the following error:

Use of unassigned local variable.

enter image description here

Code:

int c;
for (int b = 1; b < 5; b++)
{
    c = b * 2;
}

replace 

int c;

with

int c = 0; //or some other initial value

The error appears because the compiler doesn't know if the loop is ever excecuted / a value is assigned to c. So it doesn't allow you to use it Console.WriteLine(c); 

int c; // this works because the compiler knows there is a values assigned to c
c = 1;
Console.WriteLine(c);

  • +1 Thanks :) How to have : " b * ( each element of sloop)" like : 1*(1+2+3+4) And multiply each element in sloop like : 1*2*3*4 – Hung Nguyen May 23 '16 at 14:44

    @HungNguyen - this is a separate question. Please post accordingly and be sure to show what you've tried so far – Bob Kaufman May 23 '16 at 14:49

You have to assign a value to variable c before using it. like 

int c = 1;
