1. Declear 3 varibles: one of type int, one of type double and one of type string.
2. Read 3 lines of input from stdin and intialize your 3 variables
3. Print the sum of i plus your int variablke on a new line
4. Print the sum of d plus double variable to a scale of one decimal place on a new line.
5. Concatenate s with the string you read as input and print the result on a new line*/
