PLEASE NOTE: EXERCISES ARE NOT TO BE TURNED IN. FOR HOMEWORK TO BE TURNED IN, PLEASE SEE 'PROJECTS' |
|
| Ex. 1.1 | Numeric addition. Assign two new integer objects and one float object to three variable names. Sum up the three variables and assign the resulting object to a new variable name. Indicate (by printing) the value and type of this resulting object. |
| Ex. 1.2 | Numeric multiplication. Assign two new integer objects to two variable names. Multiply the two variables and assign the resulting object to a new variable name. Indicate (by printing) the value and type of this resulting variable's object. |
| Ex. 1.3 | Use strings as numbers. Starting with the sample code, sum up the values to produce the integer value 15. (Hint: apply a conversion function to each string so it can be used as a number.) |
var = '5'
var2 = '10'
|
|
Expected Output:
15 |
|
| Ex. 1.4 | Use input values as numbers. Take user input for an integer and print that value doubled. |
Sample Output:
Please enter an integer: 5 5 doubled is 10. |
|
| Ex. 1.5 | Use input as strings. Take user input for a 'place' and then greet the place enthusiastically. |
Sample program runs:
Please enter a place name: Hawaii Hello, Hawaii! |
|
Please enter a place name: Kathmandu Hello, Kathmandu! |
|
| Ex. 1.6 | String repetition. Take user input for an integer and apply that many exclamation points to the phrase, "Hello, world!" (Hint: use the "string repetition" operator) |
Sample program runs:
Please enter an integer: 2 Hello, World!! |
|
Please enter an integer: 11 Hello, World!!!!!!!!!!! |
|
| Ex. 1.7 | Round a number to integer. Assign the float value 35.30 to a variable, then round the value to 35. |
Expected Output:
35 |
|
| Ex. 1.8 | Round a number to float. Assign the float value 35.359958 to a variable, then round the value to two decimal places. |
Expected Output:
35.36 |
|
| Ex. 1.9 | Use strings in numeric division. Starting with the following code (make sure it is included exactly as written), divide the first number by the second number. |
var = "5"
var2 = "4"
|
|
Expected Output:
1.25 |
