to sum a repetition ? Mar 13th, 2009, 5:19pm   Hi there ! I'm trying to sum results of a repetitions but I didn't find out how to do it. For example : Code: x[0] = 1 x[1] = 2 x[2] = 3 for(int i=0; i<3 ; i++){ ????? } I would like to have x[0] + x[1] + x[2] = 6 I must use a "for" repetition cause there is lot's of operation in it in my sketch, so is possible to sum all the independant x[i] results to get one global x ?
