(Electrical eng.) The combined resistance of three resistors connected in parallel, as shown in Figure, is given by this formula:

Using this formula, write a C++ program to calculate and display the combined resistance when the three resistors R1 = 1000, R2 = 1000, and R3 = 1000 are connected in parallel. The output should produce this display:

The combined resistance is xxxx.xx ohms

The xxxx.xx denotes placing the calculated value in a field width of seven columns, with two positions to the right of the decimal point.
