Description: Enter a single digit contains only simple arithmetic expression string, calculate the value of the expression Note: 1, the expression containing only+,-,*,/four operators, excluding bracket 2, only the expression values contains a bit integers (0-9), and 0 as the divisor three cases to be considered by the arithmetic calculations are usually required four operations Priority 4 division with integer division, which retained only the result of integer division does not appear section. For example, 8/3 = 2. Enter the expression to ensure that no zero as the divisor happens 5, the input string must be in line with the legal meaning of the questions of expression, which includes only numeric characters and four operator characters, in addition to not contain any other characters, does not appear to calculate overflow conditions required to achieve the function: int calculate (int len, char* expStr)
