#1) If a function is legally prototyped to return an integer value, it can return a structure member that is an integer data type.
Answer: True. Any method that is not declared void must contain a return statement with a corresponding return value. The data type of the return value must match the method's declared return type; you can't return an integer value from a method declared to return a boolean.
Answer:
Follows are the matching to this question:

Explanation:
While time-consuming or prone to errors mechanical adjustments to both the referential, databases could be configured with four measures to engine violations. The restricted action causes the insert, update, and removes to only be denied. Set Null to NULL sets the invalid external key, whereas Set Default to a specific core consideration specified in SQL sets a default foreign key. Its Cascade operation spreads the main changes in external keys.
The arithmetic logic unit (ALU), which performs arithmetic and logical operations.
The control unit (CU), which extracts instructions from memory and decodes and executes them, calling on the ALU when necessary.
The fax modem is used to send and receive fax messages by only having phone line (fax machine is not required). The scanned documents should be saved as digital file (image or PDF format) in order to be sent. So, in order to send a portion of a map you should first convert the map into digital file and than simply send it through the fax modem. The best way to convert it to a digital file is to use an optical character recognition (OCR).
Answer: Probability/impact risk matrix
Explanation: Probability/impact risk matrix is type of matrix that defines the probability as well as impact that depicts whether the risk is low ,high or moderate.
Impact matrix is sort of tool which helps in conversion of any plan into a action. Probability matrix help in defining the chances in defining the risk.The positioning of the impact value of risk is plotted on the vertical axis and performance value on the horizontal axis.
Thus probability/impact matrix is the correct tool for the problem mentioned in the question.
