Examine the following for loops and determine the value of ires at the end of each of the loops, and also the number of times each loop executes.
(a)
ires = 0;
for index = -11:11
ires = ires + 1;
end
ires =
number of times
(b)
ires = 0;
for index = 10:-2:1
if index == 6
continue;
end
ires = ires + index;
end
ires =
number of times
ires = 0;
for index = 10:-2:1
if index == 6
(c)
break;
end
ires = ires + index:
end
ires =
number of times
(d)
ires = 0;
for indexl = 10:-2:1
for index2 = 2:2:index1
if index2 == 6
break
end
ires = ires + index2;
end
end
ires =
number of times (outer loop)
number of times (inner loop)
The following do...while loop rewritten as a for loop would be:
int num = 5;
do {
System.out.print(num + " " );
num *= 3; //num = num * 3;
} while (num <= 30);
All of these are correct.
int num = 5;
for (num <= 30) {
System.out.print(num + " ");
num *= 3;
}
for (int num = 5; num <= 30) {
System.out.print(num + " ");
num *= 3;
}
for (int num = 5; num <= 30; num *= 3) {
System.out.print(num + " " );
}
Convert the following for loop definition to a do while loop: for(int j= 100; j > 0; j--) {
if (j % 2 != 0) System.out.println (val); }

- Problem Description: In the Whimsical Library, each book is enchanted with a magical code to ensure the protection of knowledge. The validation process for these magical codes involves a combination of mathematical spells. The validation process is described as follows: Take the sum of the digits at odd positions from left to right. Take the sum of the squared digits at even positions from left to right. If the absolute difference between the results from step 1 and step 2 is a prime number, the book code is considered valid; otherwise, it is invalid. Example 1: Consider the magical book code 86420137. Step 1. Take the sum of the digits at odd positions from left to right. 8+4+0+3=15 Step 2. Take the sum of the squared digits at even positions from left to right. 6^2+2^2+1^2+7^2=36+4+1+49 = 90 Step 3. If the absolute difference between the results from step 1 and step 2 is a prime number. 115-901 75 (not a prime number) Book code 86420137 is invalid.

The program should print the letter E. The letter E is printed using asterisks, three across and five down. Note that this program uses System.out.print("*"); to print an asterisk without a new line. Instructions Write the nested loops to control the number of rows and the number of columns that make up the letter E. In the loop body, use a nested if statement to decide when to print an asterisk and when to print a space. The output statements have been written, but you must decide when and where to use them. Execute the program. Observe your output. Modify the program to change the number of rows from five to seven and the number of columns from three to five. What does the letter E look like now?arrow_forward
