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.
Answer:
The right approach will be "PSH".
Explanation:
- The PSH flag seems to be an acceptable solution through TCP which always encourages the submit implementation to immediately transfer data but only whenever the buffer isn't complete.
- The implementation helps to formulate this same flag towards true for something like the connection, as well as TCP will instantly begin transmitting the relevant information.
B. their fire characteristics
this should be fairly obvious
Answer:
sum = 0;for(j = 0; j < 7; j++)sum = sum + sales[5][j];
Explanation:
here we evaluate condition in parenthesis
sum = 0 here variable sum is initialised with 0 value
now for loop executes the condition in parenthesis which is (j = 0; j < 7; j++)
- j =0 is 1st condition which will be executed one time , so j = 0 means index value for loop started is with 0 as you know arrays have index
- j<7 2nd condition for executing the code block which defines loop will go on till the value of j is less than 7 ,as we know the columns in question is 7(this condition must be true)
- j++ 3rd condition means after each iteration value of j will increase +1
- here this condition is true (j = 0; j < 7; j++) till 7th column
- sum = sum + sales[5][j] (sales [row][column] it indicates every 5th row element of each column)
