Pre-Increment and Post-Increment are used frequently in conditions for loops.
Here we are playing a calculation game with Post and Pre Increment.
Example 1:
int i = 10;Console.WriteLine(i++); //=> 10Console.WriteLine(i); //=> 11
Example 2:
int i = 10;Console.WriteLine(++i); //=> 11Console.WriteLine(i); //=> 11
Example 3:
int i = 10;Console.WriteLine(i–); //=> 10Console.WriteLine(i); //=> 9
Example 4:
int i = 10;Console.WriteLine(–i); //=> 9Console.WriteLine(i); //=> 9
Example 5:
int i = 5;var result1 = i++ + ++i;Console.WriteLine(string.Format(“i=5; i++ + ++i result is : ‘{0}'”, result1)); //=> 12i = 5;var result2 = ++i + i++;Console.WriteLine(string.Format(“i=5; ++i + i++ result is : ‘{0}'”, result2)); //=> 12i = 5;var result3 = i++ – ++i;Console.WriteLine(string.Format(“i=5; i++ – ++i result is : ‘{0}'”, result3)); //=> -2i = 5;var result4 = ++i – ++i;Console.WriteLine(string.Format(“i=5; ++i – ++i result is : ‘{0}'”, result4)); //=> -1i = 5;var result5 = ++i – i++;Console.WriteLine(string.Format(“i=5; ++i – i++ result is : ‘{0}'”, result5)); //=> 0i = 5;var result6 = i++ + i++;Console.WriteLine(string.Format(“i=5; i++ + i++ result is : ‘{0}'”, result6)); //=> 11
Example 6:
int i = 5;var result1 = i– + –i;Console.WriteLine(string.Format(“i=5; i– + –i result is : ‘{0}'”, result1)); //=> 8i = 5;var result2 = –i + i–;Console.WriteLine(string.Format(“i=5; –i + i– result is : ‘{0}'”, result2)); //=> 8i = 5;var result3 = i– – –i;Console.WriteLine(string.Format(“i=5; i– – –i result is : ‘{0}'”, result3)); //=> 2i = 5;var result4 = –i – –i;Console.WriteLine(string.Format(“i=5; –i – –i result is : ‘{0}'”, result4)); //=> 1i = 5;var result5 = –i – i–;Console.WriteLine(string.Format(“i=5; –i – i– result is : ‘{0}'”, result5)); //=> 0i = 5;var result6 = i– + i–;Console.WriteLine(string.Format(“i=5; i– + i– result is : ‘{0}'”, result6)); //=> 9
