Write a C++ program which reads three values of types char, int, double and string from the keyboard and primis, appropriately formatted, assigned values and variable types. For example, if letter, number, and real are variables of type char, int and double respectively, and if the values assigned to them using cin function are: a, 1, and 3.1415, then the output should be: a is a character 1 is an integen 3.1415 is a real number
