I'm working on Project Euler, a nice site with nice programming problems. I used a jagged array for the first time in my live :-) so I think I don't understand it quit well.
I want to display the answer, the value of a jagged array at position [0][0] at the end of the file but I got an error and I don't know why. In the for loop I got the right value.
This is the error message :
Index (zero based) must be greater than or equal to zero and less than the size of the argument list.
You are using {1} to display parts2[0][0]. Since this is the first variable, this should be {0}, not 1. The argument list can be considered as an array and starts at index 0.
Change this :
// Notice this ----------------------------------------v
Console.WriteLine("The greatest sum from top to bottom is: {1}", parts2[0][0]);
// Boom !
// Index (zero based) must be greater than or equal
// to zero and less than the size of the argument list.
To this :
// Notice this ----------------------------------------v
Console.WriteLine("The greatest sum from top to bottom is: {0}", parts2[0][0]);
