how can i find the last char of an array? for example i have hello[20]; hello[0] = h hello[1] = 3 hello[2] = l hello[3] = o hello[4 and so on is blank] = i want to use the last array with value in a if else statement. Expand hello[length(hello)-1] should do it ...
In this article, we will learn how to write a C program to find sum of array elements. For example, if the array is [1, 2, 3, 4, 5] then the program should print 1+2+3+4+5 = 15 as output. We will see various different ways to accomplish this. Example 1:

2^8 is two to the power of 8 meaning 2*2*2*2*2*2*2*2 = 256 becomes INDEX($C:$C,256) and returns $C$256. Step 2 - Create an array from 1 to 255 The ROW function creates a number for each cell in a cell range. ROW($C$2:INDEX($C:$C,2^ROWS($C$2:$C$9)))-1...
