What doe the & operator do in python programming software

Suppose that you have created a program with only the following variables.int age = 34;int weight = 180;double height = 5.9;Supp

Yuri [45]

Answer:

a. calculate(age, weight); // This is legal

b. calculate(age, height); // This is legal

c. calculate(weight, height); // This is legal

d. calculate(height, age); // This is not legal

e. calculate(45.5, 120); // This is not legal

f. calculate(12, 120.2); // This is legal

g. calculate(age, size); // This is not legal

h. calculate(2, 3); // This is legal

i. calculate(age); // This is not legal

j. calculate(weight, weight); // This is legal

Explanation:

a. This is legal because the argument passed are two in numbers and they are integers but the integer for the second parameter can be cast to double.

b. This is legal because the method requires two parameter and two are passed. The method requires integer and double. The passed parameter are integer and double.

c. This is legal because the method requires two parameter and two are passed. The method requires integer and double. The passed parameter are integer and double.

d. This is not legal because even though two parameters were passed. The first one should be int but double was supplied and double cannot be downgraded to int. There is a possible lossy conversion from double to int.

e. This is not legal because even though two parameters were passed. The first one should be int but double was supplied and double cannot be downgraded to int. There is a possible lossy conversion from double to int.

f. This is legal because the method requires two parameter and two are passed. The method requires integer and double. The passed parameter are integer and double.

g. This is not legal because even though two parameters were passed. The first one should be int but the second parameter is not defined before been passed to the calculate method.

h. This is legal because the argument passed are two in numbers and they are integers but the integer for the second parameter can be cast to double.

i. This is not legal because only one parameter was passed instead of two.

j. This is legal because the argument passed are two in numbers and they are integers but the integer for the second parameter can be cast to double.

Kobotan [32]

Charles is having a lot of problems with errors in a very complicated spreadsheet that he inherited from a colleague, and he turns to another co-worker, Seymour, for tips on how to trace errors in the sheet. Seymour tells Charles that all error values begin with the same symbol, so they can be easily identified as errors.

The symbol is A)#.

Explanation:

An error is something you have done which is considered to be incorrect or wrong, or which should not have been done.
Generally errors are classified into three types: systematic errors, random errors and blunders
Error values begin with the same symbol as they are easy to identify. Once an error is identified, it can be corrected.
Error correction is the process of detecting errors in transmitted messages and reconstructing the original error-free data. Error correction ensures that corrected and error-free messages are obtained at the receiver side.
Error Correction can be handled in two ways: Backward error correction: Once the error is discovered, the receiver requests the sender to retransmit the entire data unit. Forward error correction: In this case, the receiver uses the error-correcting code which automatically corrects the errors.

The _____ constraint assigns a value to an attribute when a new row is added to a table

bixtya [17]
