Please help me to write the code in C++ language for the question below:

Write a complete program from the #include at the top through return 0; } at the bottom.

Define three char variables char1, char2, and char3

(You may also wish to define a result variable).

Have the user enter three lowercase char characters.

(You may assume that the user correctly enters three lowercase characters.)

Compare these three characters and print only the character

that appears first in the alphabet.
