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 .

For instructions that share an opcode, the funct parameter contains the necessary control codes to differentiate the different instructions. The expression inside if statement decides whether to execute the statements inside if block or under else block. My teacher gave me this example: int a = 8; int b = 4; printf("a & b = %d\n", a & b); printf("a && b = %d\n", a && b); Output: a & b = 0; a && b = 1; I'm not sure why this would return true in one scenario and false in another. 29, Jun 20.

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.
