assume that grade is a variable whose value is a letter grade- - anyone of the following letters: 'A', 'B', 'C', 'D', 'E', 'F', 'W', 'I'. Assume further there are the following int variables, declared an already initialized: account, bcount, ccount, dcount, ecount, fcount, wcount, icount. Write a switch statement that increments the apropiate variable (acount, bcount, ccount, etc ...) depending on the value of grade. So if grade is 'A' then acount is incremented; if grade is 'B' then bcount is incremented and so on.
