What is wrong with the following while repetition structure.
         while( z >= 0 )
             sum += z;

Solution


The value of the variable z is never changed in the while structure. Therefore, if the loop continuation condition ( z >= 0 ) is true, an infinite loop is created. To prevent the infinite loop, z must be decremented so that it eventually becomes less than zerobr
