Olympiad Test: Introduction To Q Basic - 2 - Class 6 MCQ

The error in the given QBASIC program is on line 30. The correct syntax for the IF statement in QBASIC is "IF condition THEN statement". However, in this program, the condition is missing after the IF statement.
To fix the error, the program should be modified as follows:
10 PRINT "Enter a number, zero to stop:";
20 INPUT A
30 IF A <> 0 THEN GOTO 70
40 LET A = A + 10
50 PRINT "The number plus 10 is", A
60 GOTO 10
70 STOP
Explanation:
- Line 10: Displays the message "Enter a number, zero to stop:".
- Line 20: Takes input from the user and stores it in variable A.
- Line 30: Checks if A is not equal to zero. If true, it jumps to line 70. This condition is necessary to stop the program when the user enters zero.
- Line 40: Adds 10 to the value of A.
- Line 50: Prints the message "The number plus 10 is" followed by the value of A.
- Line 60: Jumps to line 10 to repeat the process.
- Line 70: Stops the execution of the program.
Therefore, the corrected program will print the value of A plus 10 when A is not equal to zero.

To run the program, follow these steps:
1. Open the Program: Locate the program that you want to run.
2. Click on the Command Prompt: Open the Command Prompt by pressing the Windows key + R, type "cmd", and press Enter.
3. Navigate to the Program's Directory: Use the "cd" command to navigate to the directory where the program is located. For example, if the program is in the "C:\Programs" directory, type "cd C:\Programs" and press Enter.
4. Run the Program: Once you are in the program's directory, type the name of the program's executable file (e.g., "program.exe") and press Enter. The program will then run.
Alternatively, you can also run the program by following these steps:
1. Locate the Program: Find the program that you want to run.
2. Right-Click on the Program: Right-click on the program's icon.
3. Select "Run as Administrator": From the context menu that appears, select the "Run as Administrator" option.
4. Confirm the Action: If prompted, click "Yes" or enter the administrator password to confirm the action.
By following these steps, you will be able to run the program successfully.

To determine whether Name$ is a numerical constant, numerical variable, string constant, or string variable, we need to understand the characteristics and definitions of each term.
Numerical Constant:
- A numerical constant is a fixed value that does not change during the execution of a program.
- It represents a specific number or value.
- Examples of numerical constants include 1, 3.14, -5, etc.
Numerical Variable:
- A numerical variable is a storage location that can hold numerical values.
- It can be assigned different values during the execution of a program.
- Examples of numerical variables include x = 5, y = 10, etc.
String Constant:
- A string constant is a sequence of characters enclosed in quotation marks.
- It represents a fixed string value that does not change during program execution.
- Examples of string constants include "Hello", "World", etc.
String Variable:
- A string variable is a storage location that can hold a sequence of characters (string).
- It can be assigned different string values during program execution.
- Examples of string variables include name = "John", message = "Welcome", etc.
Based on the given information, Name$ is a string variable because it has the following characteristics:
- It starts with a capital letter, indicating it is a variable.
- The presence of the "$" symbol suggests it may be a string variable.
- The name itself, "Name$", implies it is storing a value related to a name or string.
Therefore, the correct answer is option D: String Variable.

To determine the operator that is not a QBASIC operator, let's analyze each option:
A:

< =

- This is the less than or equal to operator in QBASIC.
B:

> =

- This is the greater than or equal to operator in QBASIC.
C:

< >

- This is the not equal to operator in QBASIC.
D:

- >

- This is not a valid QBASIC operator.
Therefore, the correct answer is option D:

- >

. This is not a QBASIC operator.
QBASIC operators include arithmetic operators (+, -, *, /), relational operators (<, >, <=, >=, =, <>), logical operators (AND, OR, NOT), assignment operators (=, +=, -=, *=, /=), and string operators (&). However, the operator "->" is not a valid QBASIC operator.
Remember, when solving multiple-choice questions, it is important to carefully analyze each option before selecting the correct answer.

The code provided is a loop that will continue executing as long as the variable C is less than 10. Within the loop, the value of C is incremented by 1. After each iteration of the loop, the value of C is printed.
Let's analyze the code step by step:
1. Initially, the value of C is set to 0 using the statement "LET C = 0".
2. The loop is entered, and the condition "C < 10" is checked. Since C is currently 0, the condition is true, and the loop body is executed.
3. Inside the loop, the value of C is incremented by 1 using the statement "LET C = C + 1". So, the new value of C becomes 1.
4. The loop continues to iterate, and the condition is checked again. Since C is still less than 10, the loop body is executed again.
5. The value of C is incremented by 1 again, making it 2.
6. Steps 4 and 5 are repeated until C reaches 10.
7. When C becomes 10, the condition "C < 10" becomes false, and the loop is exited.
8. Finally, the value of C, which is 10, is printed using the statement "PRINT C".
So, the final value that will be printed after the successful execution of the code is 10.
Answer: C

Explanation:
The output of the program is: "MYNAMEISMANMOHAN"
Here's how the program works:
1. The CLS command clears the screen.
2. The LET statement is used to assign values to variables.
- X$ is assigned the value "MY NAME"
- Y$ is assigned the value "IS"
- Z$ is assigned the value "MANMOHAN"
3. The PRINT statement is used to display the values of the variables on the screen.
- X$ is displayed first, followed by a space.
- Y$ is displayed next, followed by a space.
- Z$ is displayed last.
Since there are no commas or additional spaces in the PRINT statement, the values of the variables are concatenated together without any spaces in between. Hence, the output is "MYNAMEISMANMOHAN".
Answer: B

The MOD operator, also known as the modulus operator or remainder operator, is used to find the remainder of a division operation. When two numbers are divided, the MOD operator returns the remainder as the result.
Here is a detailed explanation:
A: Quotient of a division operation:
- The quotient is the result of dividing one number by another.
- It represents how many times the divisor can be subtracted from the dividend.
- The quotient is not found using the MOD operator.
B: Remainder of a division operation:
- The remainder is the value left over after the division operation.
- It represents the part of the dividend that could not be evenly divided by the divisor.
- The remainder is found using the MOD operator.
C: Dividend of a division operation:
- The dividend is the number being divided.
- It is the total quantity that is being divided into equal parts.
- The dividend is not found using the MOD operator.
D: Divisor of a division operation:
- The divisor is the number by which the dividend is divided.
- It represents the number of equal parts the dividend is divided into.
- The divisor is not found using the MOD operator.
Therefore, the correct answer is Option B: Reminder of a division operation, as it accurately describes the purpose of the MOD operator.

The shortcut keystroke for PRINT is Ctrl + P

Explanation:
The QBASIC code given initializes two string variables, firstword$ and secondword$, with the values "wicket" and "keeper" respectively.
The PRINT statement is used to display the values of these two variables.
When the PRINT statement is executed, it concatenates the values of firstword$ and secondword$ and displays the result.
Therefore, the output of the code will be "wicketkeeper".
Answer: A
