Question

in c++ codeblocks

Convert the following code into a switch structure. Make the switch structure as short as possible (do not repeat code). if (i == 3 || i == 5) { n++; tryagain = 0; } else if (i == 4) || i == 10) { n = 5; } else if (i == 6) { n = 6; } else { n = 0; tryagain = 1; }

Write an if statement that will give 5 extra credit points to students who answer Question A correctly, and 10 extra points if they answer Question A and Question B correctly. Name the variable intBonus.

Answer 1

So, here we want to convert a nested loop to switch:

Steps to follow:

1. Pass the argument which we wan to check to the switch statement.
2. Now, for every condition, use a case.
3. For OR ("||") operations, we can use two switch statements together.

Please refer to the comments of the program for more clarity.

    // Starting of the switch block
    switch(i)
    {
       case 3:    // For (i == 3 || i == 5)
       case 5:
        {
            n++; tryagain = 0;
            break;
        }

       case 4:    // For (i == 4 || i == 10)
       case 10:
        {
            n = 5;
            break;
        }
       case 6:   // For (i == 6)
        {
            n = 6;
            break;
        }
       default:  // For others
        {
            n = 0; tryagain = 1;
            break;
        }
    }  // End of the switch block

Now, as asked lets see an example of if statement, using variable, intBonus:

In the below code, we care finding the intBonus using the if-statements,

I have applied if conditions on variable "workExperience" and calculated intBonus. You can interchange the variables according to your requirement.

#include<bits/stdc++.h>
using namespace std;

int main()
{
    int intBonus = 0;  // Initializing intBonus as 0
    int workExperience = 0; // Initializing workExperience as 0
    cout << "Enter your work experience: ";
    cin >> workExperience;  // Taking input

    // calculating the bonus using the if statements
    if(workExperience >= 2 && workExperience < 5)
    {
        intBonus = 1000;
    }
    else if(workExperience >= 5)
    {
        intBonus = 5000;
    }
    else
    {
        intBonus = 500;
    }
    cout << "\n\nYour Bonus: " << intBonus << endl;  // Printing the output
    return 0;
}
