output will be -1.... because inwhile +(+i--)!=0 () have higher precedence then control goes to in parenthses and unary plus and ++ have the same precedece in table then we chek the associativty which is right to left i++ is evaluate first then the value of i will not chang withn a same expression because its a post fix increment now expression become +(+0)!=0 and unary plus have no effect then expression look lyk 0!=0 this condition is false then while block of code will not execute and nw i become -1 and we try to print like this printf("%d",-1); then output will -1

In a gymnastic competition, scoring is based on the average of all scores given by the judges excluding the maximum and minimum scores. Let the user input the number of judges, after that, input the scores from the judges. Output the average score. Note: In case, more than two judges give the same score and it happens that score is the maximum or minimum then just eliminate two scores. For example, if the number of judges is 5 and all of them give 10 points each. Then the maximum and minimum score is 10. So the computation would be 10+10+10, this time. The output should be 10 because 30/3 is 10.
