Explanation of Solution
Given code:
//Declare the variables
int x = 1, total;
//Execute "while" loop
while (x <= 10)
{
//Perform calculation
total += x;
//Increment "x" by "1"
++x;
}
Error:
In the given code, the variable “total” is not initialized to perform the calculation.
Corrected code:
//Declare and initialize the variable
int x = 1, total=0;
//Execute "while" loop
while (x <= 10)
{
//Per...
Explanation of Solution
Given code:
//Execute "while" loop
while (x <= 100)
//Perform calculation
total += x;
//Increment "x" by "1"
++x;
Error:
In the given code, the body of “while” is not properly enclosed.
Corrected code:
//Execute "while" loop
while (x <= 100)
{
//Perform calculation
total += x;
//Increment "...
Explanation of Solution
Given code:
//Execute "while" loop
while (y > 0)
{a
//Print the value of "y"
System.out.println(y);
//Increment "y" by "1"
++y;
Error:
- In the given code, the body of “while” is not properly enclosed.
- The letter “a” given after opening brace “{” is not related to any syntax and it leads to an error.
Corrected code:
//Execute "while" loop
while (y > 0)
{
//Print the value of "y"

EBK JAVA HOW TO PROGRAM, LATE OBJECTS
- C Programming Language (Code With C Programming Language) Problem Title : Visible Trees There is a legend about a magical park with N × N trees. The trees are positioned in a square grid with N rows (numbered from 1 to N from north to south) and N columns (numbered from 1 to N from west to east). The height (in metres) of each tree is an integer between 1 and N × N, inclusive. Magically, the height of all trees is unique. Bunga is standing on the northmost point of the park and wants to count the number of visible trees for each Column. Similarly, Lestari is standing on the westmost point of the park and wants to count the number of visible trees for each Row. A tree X is visible if all other trees in front of the tree X are shorter than the tree X. For example, let N = 3 and the height (in metres) of the trees are as follows6 1 87 5 32 9 4 On the first column, Bunga can see two trees, as the tree on the third row is obstructed by the other trees. On the second column, Bunga can see…arrow_forward#python def add_func(a,b): print(f"add_func output for 1 + 2: {add_func(1, 2)}") print(f"add_func output for good + day: {add_func('good',' day')}") (add_func(1,2) = 3, (add_func('good',' day') = "good day"arrow_forwardint f(int &k){k++;return k * 2;}int main(){int i = 1, j = -1;int a, b, c;a = f(i) + i/2;b = j + f(j) + f(j);c = 2 * f(j);return 0;} What are the values of a, b and c id the operands in the expressions are evaluated from left to right and then what are the values when its evaluated right to left?arrow_forward
- Broken Cabins Problem Statement: There is an Office consisting of m cabins enumerated from 1 to m. Each cabin is 1 meter long. Sadly, some cabins are broken and need to be repaired. You have an infinitely long repair tape. You want to cut some pieces from the tape and use them to cover all of the broken cabins. To be precise, a piece of tape of integer length t placed at some positions will cover segments 5,5+1-sit-1. You are allowed to cover non-broken cabins, it is also possible that some pieces of tape will overlap. Time is money, so you want to cut at most k continuous pieces of tape to cover all the broken cabins. What is the minimum total length of these pieces? Input Format The first line contains three integers n,m and k(1sns10°, namsloº, Isksn) - the number of broken cabins, the length of the stick and the maximum number of pieces you can use The second line contains n integers bl,b2,bn (Isbism) - the positions of the broken cabins. These integers are given in increasing…arrow_forwardQ1:Find the output of the following code:arrow_forwardCode Simulation – Identify the error/mistake or output in the code fragment below: CODE FRAGMENT IDENTIFIED ERROR/MISTAKE/OUTPUT tinclude 1. using namespace std; void multiply(int x, int y) { return x * y; } int main () cout ng namespace std; t multiply (int x, int y) int product{ x * y }; t main() cout « multiply (4) using namespace std; int add (int x, int y, int z) { return x + v + z:arrow_forward
- When you perform arithmetic operations with operands of different types, such as adding an int and a float, ____________. C# chooses a unifying type for the result you must choose a unifying type for the result you must provide a cast you receive an error messagearrow_forward(Numerical) Write a program that tests the effectiveness of the rand() library function. Start by initializing 10 counters to 0, and then generate a large number of pseudorandom integers between 0 and 9. Each time a 0 occurs, increment the variable you have designated as the zero counter; when a 1 occurs, increment the counter variable that’s keeping count of the 1s that occur; and so on. Finally, display the number of 0s, 1s, 2s, and so on that occurred and the percentage of the time they occurred.arrow_forward(Electrical eng.) a. An engineer has constructed a two-dimensional array of real numbers with three rows and five columns. This array currently contains test voltages of an amplifier. Write a C++ program that interactively inputs 15 array values, and then determines the total number of voltages in these ranges: less than 60, greater than or equal to 60 and less than 70, greater than or equal to 70 and less than 80, greater than or equal to 80 and less than 90, and greater than or equal to 90. b. Entering 15 voltages each time the program written for Exercise 7a runs is cumbersome. What method could be used for initializing the array during the testing phase? c. How might the program you wrote for Exercise 7a be modified to include the case of no voltage being present? That is, what voltage could be used to indicate an invalid voltage, and how would your program have to be modified to exclude counting such a voltage?arrow_forward
- (Numerical) Write and test a function that returns the position of the largest and smallest values in an array of double-precision numbers.arrow_forward(Numerical) Using the srand() and rand() C++ library functions, fill an array of 1000 floating-point numbers with random numbers that have been scaled to the range 1 to 100. Then determine and display the number of random numbers having values between 1 and 50 and the number having values greater than 50. What do you expect the output counts to be?arrow_forward(Data processing) Your professor has asked you to write a C++ program that determines grades at the end of the semester. For each student, identified by an integer number between 1 and 60, four exam grades must be kept, and two final grade averages must be computed. The first grade average is simply the average of all four grades. The second grade average is computed by weighting the four grades as follows: The first grade gets a weight of 0.2, the second grade gets a weight of 0.3, the third grade gets a weight of 0.3, and the fourth grade gets a weight of 0.2. That is, the final grade is computed as follows: 0.2grade1+0.3grade2+0.3grade3+0.2grade4 Using this information, construct a 60-by-7 two-dimensional array, in which the first column is used for the student number, the next four columns for the grades, and the last two columns for the computed final grades. The program’s output should be a display of the data in the completed array. For testing purposes, the professor has provided the following data:arrow_forward
