Write a C++ program that converts a string to a float value. For example, given the string "12.34" the program should output a float value 12.3400. Don't use the string stream class or any predefined functions that can do this conversion for you. However, you should write your own code to do the conversion for at least 4 digits after the decimal point. Sample input/output is shown below and your code should work for any input given by the user. Input: 19.3473 Output: 19.3473 Define a class named intmod that stores an integer and has functions to get and set the integer's value. Then, overload the [ ] operator so that the index returns the digit in position /, where / = 0 is the most-significant digit. If no such digit exists then -1 should be returned. Sample input/output is shown below and your code should work for any input. Input: 547 Output: 0 5 1 4 2 7
