Do it in C or C++

Calculate a given expression consisting of natural numbers less than 10 (1, 2, 3,..,9), binary operators (+,-, *, / ), and parentheses. Provide the result to the second decimal place by rounding off (e.g., 5/3- 1.67) Your program will get a string of an expression from "input_calc.txt" file and is requred to write the result to "output_calc.txt" file. You can assume that there is no blank space in input strings Refer the following example: inputcalc.txt output calc.txt 11.00 5+3 2 Another example: input calc.txt outputcalc.txt 16.33 Note that, the length of input expression does not exceed 100, and your program has to produce an answer within 5 seconds
