The objective is to write a C program that takes a range of numbers as input and prints all the numbers within that range.

For example, if the range is from 1 to 10, the program should output: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10.

Getting Started

To begin, let’s outline the basic structure of the program. We will use the standard C programming language.

Here’s a simple program skeleton to build upon:

#include <stdio.h>

int main() {
    // Code to print numbers in a given range
    
    return 0;
}

Inputting the Range

To create an interactive program, we can prompt the user to enter the range of numbers they want to print.

Utilizing the scanf function, we can read the lower and upper limits of the range from the user.

Here’s an example code snippet:

#include <stdio.h>

int main() {
    int lowerLimit, upperLimit;
    
    printf("Enter the lower limit of the range: ");
    scanf("%d", &lowerLimit);
    
    printf("Enter the upper limit of the range: ");
    scanf("%d", &upperLimit);
    
    // Code to print numbers in the given range
    
    return 0;
}

By using the printf and scanf functions, we can prompt the user to input the lower and upper limits of the range, stored in the variables lowerLimit and upperLimit, respectively.

Printing Numbers in the Given Range

Now, let’s write the code that prints the numbers within the range. We can achieve this with a loop, specifically the for loop, which iterates over a range of values.

#include <stdio.h>

int main() {
    int lowerLimit, upperLimit;
    
    printf("Enter the lower limit of the range: ");
    scanf("%d", &lowerLimit);
    
    printf("Enter the upper limit of the range: ");
    scanf("%d", &upperLimit);
    
    printf("Numbers in the given range: ");
    
    for (int i = lowerLimit; i <= upperLimit; i++) {
        printf("%d ", i);
    }
    
    return 0;
}

In the above code snippet, we added a for loop that starts from the lower limit and continues until the upper limit.

Within each iteration, the loop prints the value of i, representing the current number in the range.

Sample Output

Let’s run our program with a sample input range from 1 to 10:

Enter the lower limit of the range: 1
Enter the upper limit of the range: 10
Numbers in the given range: 1 2 3 4 5 6 7 8 9 10

As seen, the program successfully generates and displays all the numbers within the specified range.

FAQs

Q1: What is the purpose of this program?

This program generates and prints all the numbers within a given range, providing a useful tool for various mathematical and programming applications.

Q2: Can I input a negative range?

Yes, a negative range is allowed. The program effectively handles both positive and negative ranges.

Q3: Is there a limit to the range of numbers that can be entered?

There is no inherent limit to the range of numbers that can be entered. However, extremely large ranges may consume excessive memory and computational resources.

Q4: How can I modify the program to print only even numbers within the range?

To modify the program to print only even numbers within the range, adjust the loop’s increment step to i += 2 instead of i++. This way, the loop only considers even numbers.

Q5: Can I use decimal numbers in the range?

No, the program is designed for integer numbers only. Decimal numbers are not supported in this implementation.

Q6: What should I do if I encounter any errors while running the program?

If errors occur while running the program, double-check the code for typos or syntax mistakes. Additionally, ensure a suitable C compiler is installed on your system.
