The array index in C starts with 0 because the name of an array is a pointer that is a reference to a memory location and the index is used as an offset. Hence, an expression *(arr + n) or arr[n] locates an element n-locations away from the starting loca

Mouse Problem: Why do I keep getting the error message, "Array indices must be positive integers or logical values."?loop, then mod(i+1,5) is mod(4+1,5) which is mod(5,5) which is 0. You then try to use that 0 to index x.
j = (int)((index / Integer.MAX_VALUE) % Integer.MAX_VALUE); k = (int)(index % Integer.MAX_VALUE); return array[i][j][k]; }I completed it, then tried testing with Long.MAX_VALUE as the size: java.lang.OutOfMemoryError. Specifying Integer.MAX_VALUE as the size: java.lang.Out...
The section of code with n(p/0.01) also looks like it might be missing a multiplication operator. If it isn't and you intended p/0.01 to give you an integer value you can use as an index into n, you may encounter difficulties due to floating point ar...

Notice that the Python indexing is 0-based, so the second element has the index 1. Finally, you are printing arr_2 to verify that it is a 2x2 array. Now you should see what happens when you change a value in arr_2. Like in the MATLAB example, you should change the upper left ...
numbers; for an array of integers in java or c#. then, you can initialize it with values like int[] numbers = {1, 2, 3, 4, 5}. how do i access elements in an array? array elements are accessed using their index, which starts at 0. for example, to access the first element in...
