Write a program in c++ that converts kilograms to pounds, and vice versa. Your program should ask the user to input one of the following:

a number followed by k

a number followed by l

The k and l represent kilograms and pounds, respectively. Your program reads the number in one unit, converts it to the other unit, and outputs the result.

Note that the conversion equations are:

kg = 0.4535970244 lb

lb = 2.2046 kg

For the conversion rates, you must use named constants.

Running sessions of your program should look like the following:

Enter a weight (e.g., 73k, 160l) => -34k

Invalid weight... The weight should be zero or positive

Enter a weight (e.g., 73k, 160l) => 34g

Invalid unit... The unit should be either k or l

Enter a weight (e.g., 73k, 160l) => 43k

43kg is 94.7978 lb
