Write a C program that prints the alphabet in lowercase

PublishedJune 5, 2022

Heya! 👋 I love helping people, and one of the best ways I do this is by sharing my knowledge and experiences. My journey reflects the power of growth and transformation, and I’m here to document and share it with you.

I started as a pharmacist, practicing at a tertiary hospital in the Northern Region of Ghana. There, I saw firsthand the challenges in healthcare delivery and became fascinated by how technology could offer solutions. This sparked my interest in digital health, a field I believe holds the key to revolutionizing healthcare.

Determined to contribute, I taught myself programming, mastering tools like HTML, CSS, JavaScript, React, PHP, and more. But I craved deeper knowledge and practical experience. That’s when I joined the ALX Software Engineering program, which became a turning point. Spending over 70 hours a week learning, coding, and collaborating, I transitioned fully into tech.

Today, I am a Software Engineer and Digital Health Solutions Architect, building and contributing to innovative digital health solutions. I combine my healthcare expertise with technical skills to create impactful tools that solve real-world problems in health delivery.

Imposter syndrome has been part of my journey, but I’ve learned to embrace it as a sign of growth. Livestreaming my learning process, receiving feedback, and building in public have been crucial in overcoming self-doubt. Each experience has strengthened my belief in showing up, staying consistent, and growing through challenges.

Through this platform, I document my lessons, challenges, and successes to inspire and guide others—whether you’re transitioning careers, exploring digital health, or diving into software development.

I believe in accountability and the value of shared growth. Your feedback keeps me grounded and motivated to continue this journey. Let’s connect, learn, and grow together! 🚀

Solve the problem with a `while loop`

#include <stdio.h>

int main(void)
{
    /* Declare a variable and initialize it with the first member of 
       the range [a - z] 
    */

    char alphabet = 'a';

     /* check to see if the current value of your variable is less than 
         or the same as the last member (z) of the given range. While 
         the value is less, go ahead and print the value 
      */

    while (alphabet <= 'z')
    {
        // print the value of the variable 
        putchar(alphabet);

        // increment the variable (ie: a becomes b)
        alphabet++;
    }

    putchar('\n');
    return (0);
}

The output of the above code is:

abcdefghijklmnopqrstuvwxyz

Solve the problem with a `for loop`

The logic behind the for loop isn't much different from that of the while loop. However, they have different syntax, so you just have to pay attention to how the loops are supposed to be written.

#include <stdio.h>

int main(void)
{
    //declare a variable
    char alphabet;

    for (alphabet = 'a'; alphabet <= 'z' ; alphabet++)
    {
        // print the value of the variable 
        putchar(alphabet);

    }

    putchar('\n');
    return (0);
}

The output of the above code is:

abcdefghijklmnopqrstuvwxyz

Conclusion

I hope you enjoyed reading this and it made you understand how to solve a problem like this. I would like to hear back from you. Is there anything I missed, or explained wrongly, or something you want me to elaborate more on?

Share with me what you also think. Mind you, I am also learning and your feedback will be valuable to me.

Thanks for reading and I would love to connect personally with you. If you are on Twitter, then you can send me a DM and let's have a good chat.
