I've created code to read a user's number and change it into an int. Essentially my code looks like this
while (e != 1)
{
int num = Convert.ToInt32(Console.ReadLine());
e += 1;
}
How do I reuse the 'int num' outside of the loop?
You can declare num
outside of the loop but assign to it inside the loop:
int num = 0; // Or some other default value
while (e != 1)
{
num = Convert.ToInt32(Console.ReadLine()); // Note that num is NOT declared here
e += 1;
}
// Use num here
