Variable might not have been initialized error

Question

When i try to compile this:

public static Rand searchCount (int[] x) 
{
    int a ; 
    int b ; 

    ...   

    for (int l= 0; l

        

Answer 1

You declared them, but not initialized.

int a; // declaration, unknown value
a = 0; // initialization
int a = 0; // declaration with initialization
