Stupid Q from a newbie

[neildemeester]

double grades[13] = {0,2,1.75,1.5,1.25,1,.75,.5,-.75,-1,-1.25,-1.5,-2};
double grade1 = 0;
double grade2 = 0;
double grade3 = 0;
double grade4 = 0;
double grade5 = 0;

Why can't I do this after I get user input into my grade variables?


amount = grades[grade1] + grades[grade2] + grades[grade3] + grades[grade4] + grades[grade5];

Sorry if its a stupid question.
Thanks

And which values have you enterd?

(It's probably becasue array element index must be int number so it doesn't allow type of double which is number of type real)
