I started a programming course about a month ago, recently we started learning about using different code outside the main string and using them in order to pass data to each other I really got lost and didn't understand a word, wonder if anyone could help explain how it works, we were given some examples to test out. I will list two of the examples below.
1)
static int number0()
{
int value = 0;
return value;
}2)
static double circum (float radius)
{
double circle = (double)radius;
circle = System.Math.PI * radius * 2;
return circle;
}
