If the cost of one type of phone service is $7.45 plus 6.9 cents for each unit used over 56 units, write enough C++ code to display the correct charge for phone service if the variable UNITS contains the units used. No functions (including the main() function) or comments are necessary and any variables that you use will be assumed to be of type double. You may assume that UNITS will contain a non-negative int after input.

// assume the following lines have executed

int UNITS;

cin >> UNITS;
