difference between i and i + 1 in c

SI = P * 2 * 10/100 SI = 0.2 P CI = P * (1 + 10/100)^2 - P CI = P * 1.1^2 - P CI = 1.21 P - P CI = 0.21 P Given, CI - SI = 50 0.21 P - 0.2 P = 50 0.01 P = 50 P … Behavior of sizeof operator . this is true if i is a built-in type .

Why continue counting/certifying electors after one candidate has secured a majority? In general, I'd use inc(i) wherever it's obviously being used only as a loop/index of some sort, and + 1 wherever the 1 would make the code easier to maintain (ie, it might conceivable change to another integer in the future) or just more readable from an algorithm/spec point of view.
