- add all the numbers up and divide by how many numbers there are.
Answer:
c)Banana * daco;
Explanation:
To declare an variable pointer we use * symbol after writing it's type.For example int *.Then we write the name of the variable since the name of the variable is daco.The class is a user defined data type so instead of writing any data type we will write class name then the * then name of the variable.
Banana * daco; which matches the option c Banana* daco;
According to the given question, sales is a two-dimensional array and contains 10 rows and 7 columns wherein each component is of type integer and the variables sum and j are also of integer type.
<u>Explanation:</u>
In order to find the sum of the elements of the fifth row of sales, the correct piece of code should be:
sum=0;
for(j=0;j<7;j++)
sum=sum+sales[4][j];
The indexing in an array always starts from zero, therefore, to calculate the sum of the fifth row, the user has to write 4 in the index to point to the fifth row.

The ____ operator executes one of two expressions based on the results of a conditional expression.
a. .
b. ( )
c. ,
d. ?:
Answer:
(d) ? :
Explanation:
The ternary operator (? :) is an operator that executes one out of two expressions based on the results of a conditional expression. It is a faster or shorthand way of writing an if ... else statement. The operator checks the conditional expression and depending on whether it is true or false, one of its two statements will be executed. For example:
String correct = (4 < 5) ? "yes" : "no" ;
In the code above,
i. the conditional statement is (4 < 5) and this will be tested for to return true or false.
ii. the first expression (the one after the ?) is "yes" which will be executed if the conditional statement returns true.
iii. and the second expression (the one after the : ) is "no" which will be executed if the conditional statement returns false.
Therefore, since the conditional expression returns true for 4 < 5, the first expression will be executed. i.e "yes". This means that the String variable <em>correct </em> will have a value of "yes".
