Answer:
Explanation:
The following is written in Java. It creates the function num_eights and uses recursion to check how many times the digit 8 appears in the number passed as an argument. A test case has been created in the main method and the output can be seen in the image below highlighted in red.
public static int num_eights(int pos){
if (pos == 0)
return 0;
if (pos % 10 == 8)
return 1 + num_eights(pos / 10);
else
return num_eights(pos / 10);
}
Answer:
Following is the algorithm to interchange the value of two variable x and y.
step 1:Read the two integer x and y.
step 2 :t=x
Step 3: x=y
step 4: y=t
The minimum number of assignment to do this is 3
Explanation:
After reading two integer x & y, create a variable "t" of integer type.
with the help of variable "t", we can swap the value of variable x and y.
It requires 3 assignment to interchange the value.
Typically, "Del" stands for "delete."
Most times, this key will do different things depending on the type of keyboard/computer you have. For example, on macs, the "delete" key is also the backspace key, so it will delete the last character you typed. However, on most pcs, the "delete" key will delete characters you typed that are in front of your cursor.
