Day 0: Data Types

• The Input to the function is an integer, float, and string
• The Output of the function is the sum of the integer, float, and string

Explanation

• i, d, s are the three variables of different data types. i is an integer, d is a double, and s is a string then we declared the three variables i2, d2, s2 of different data types. i2 is an integer, d2 is a double, and s2 is a string and we take the input from the user and store it in the variables i2, d2, s2.
• Then we add the integer and double and print the result and round the result to the 1 decimal place.
• Then we concatenate the string and print the result.
