Solution

Source code after correcting error is given below,

Source code :

#include <iostream>
using namespace std;

int main() {
cout << \"Welcome to Loop World\" << endl;

// SECTION I: There is no error in section 1. it is giving correct output.

cout << endl;
cout << \"******************\" << endl;
cout << \"Section I\" << endl;
cout << \"******************\" << endl;

short sum; // Accumulates the total
short i; // Used as loop control variable
for (i = 1; i < 5; ++i) {
sum += i;
}
cout << \"The sum of the numbers from 1 to 5 (inclusive) is: \" << sum << endl;

// SECTION II: There is no error in section 1. it is giving correct output.

cout << endl;
cout << \"******************\" << endl;
cout << \"Section II\" << endl;
cout << \"******************\" << endl;

double total; // Accumulates total
double price; // Gets next price from user
short num_items; // Number of items
short counter = 1; // Loop control counter

cout << \"How many items do you have? \";
cin >> num_items;
cout << endl;

while (counter <= num_items) {
total = 0;
cout << \"Enter the price of item \" << counter << \": \";
cin >> price;
cout << endl;
total += price;
counter++;
}
cout << \"The total price is: \" << total << endl;

// SECTION III: Here the error is inside Do while loop you didn\'t give a statement to increment counter value by 1 in // each iteration. you have to give counter++ inside Do while loop. otherwise the loop will not stop it will work // infinitely.
// we need to stop the loop when the counter value becomes 5. because we need to calculate sum of // 1 to 4(inclusive) integers.

cout << endl;
cout << \"******************\" << endl;
cout << \"Section III\" << endl;
cout << \"******************\" << endl;

cout << \"I will now calculate \";
cout << \"the sum of numbers from 1 to 4 (inclusive)\" << endl;

sum=0;
counter = 1;

do {
sum += counter;
cout << \"Sum so far: \" << sum << endl;
counter++;
} while (counter <= 4);

cout << endl << \"Section III Recap\" << endl;

cout << \"I calculated the sum of numbers from 1 to 4 (inclusive) as \" << sum << endl;

// SECTION IV: here the error is inside for loop you have given i++ instead of i--. you have to decrement i value by //1,because you have started i value from 4.so you have to decrement i value by 1 in each iteration and we have to //reach at a value 1.therefor give i--.

cout << endl;
cout << \"******************\" << endl;
cout << \"Section IV\" << endl;
cout << \"******************\" << endl;

cout << \"I will now calculate \";
cout << \"the sum of squares from 1 to 4 (inclusive)\" << endl;

sum = 0;
for (i=4; i>0; i--) {
sum += i*i;
}

cout << \"The sum of squares from 1 to 4 is: \" << sum << endl;

// SECTION V: here the error is you have given a value 10 to compare with counter value in while loop condition //statement. we are calculating sum of cubes only from the value 1 to 4(inclusive.). so you should give \'4\' instead of
// \'10\'.

cout << endl;
cout << \"******************\" << endl;
cout << \"Section V\" << endl;
cout << \"******************\" << endl;

cout << \"I will now calculate \";
cout << \"the sum of cubes from 1 to 4 (inclusive)\" << endl;

sum = 0;
counter = 1;
  
while (counter <= 4) {
sum += (counter * counter * counter);
counter++;
}

counter++;

cout << \"The sum of cubes from 1 to 4 is: \" << sum << endl;

cout << endl;
cout << \"******************\" << endl;
cout << \"Section Done\" << endl;
cout << \"******************\" << endl;

cout << endl << \"Congrats! You fixed them all (hopefully correctly!)\" << endl << endl << \"Goodbye\" << endl << endl;

return 0;
}
