(Civil eng.) Write a C++ program to calculate and display the maximum bending moment, M, of a beam that’s supported on both ends (see Figure). The formula is M = XW (L - X) / L, where X is the distance from the end of the beam that a weight, W, is placed, and L is the beam’s length. You program should produce this display:

The maximum bending moment is xxxx.xxxx

The xxxx.xxxx denotes placing the calculated value in a field wide enough for four places to the right and left of the decimal point. For your program, assign the values 1.2, 1.3, and 11.2 to X, W, and L.
