What is Camel Case?

Before we dive into the details of finding camel case without using library functions, let’s first understand what camel case is.

Camel case is a naming convention where multiple words are joined together without spaces, and the first letter of each subsequent word is capitalized.

This style is often used in programming to create variable names, function names, and class names that are easily readable and understandable.

For example, “camelCase” and “findCamelCase” are both examples of camel case.

C Program to Find Camel Case without using Library Function

Now, let’s explore how we can write a C program to find camel case without relying on any library functions.

The program will take an input string from the user and determine whether it follows the camel case naming convention.

#include <stdio.h>

int main() {
    char input[100];
    int i, flag = 0;

    printf("Enter a string: ");
    fgets(input, sizeof(input), stdin);

    for (i = 0; input[i] != '\0'; i++) {
        if (input[i] >= 'A' && input[i] <= 'Z') {
            flag = 1;

    if (flag)
        printf("The string follows the camel case convention.\n");
        printf("The string does not follow the camel case convention.\n");

    return 0;

In the above program, we first declare an array to store the input string provided by the user.

We initialize a flag variable as 0, which will help us determine if the input string follows the camel case convention.

The program prompts the user to enter a string using the printf function.

We then use the fgets function to read the input string from the user, ensuring that it doesn’t exceed the size of the input array.

Next, we iterate through each character of the input string using a for loop.

Within the loop, we check if the current character is an uppercase letter (between ‘A’ and ‘Z’).

If we encounter an uppercase letter, we set the flag variable to 1 and break out of the loop. This indicates that the string follows the camel case convention.

After the loop, we check the value of the flag variable. If it is 1, we print a message stating that the string follows the camel case convention. Otherwise, we print a message indicating that the string does not follow the camel case convention.

Frequently Asked Questions (FAQs)

Q: Can I use a library function to achieve the same result?

A: Yes, there are library functions available that can help you determine whether a string follows the camel case convention. However, the purpose of this program is to showcase how to achieve the same result without relying on any external libraries.

Q: How can I modify this program to handle multiple words?

A: The current program checks whether there is at least one uppercase letter in the string. To handle multiple words, you can modify the program to count the number of uppercase letters and consider it as an indicator of multiple words.

Q: Are there any limitations to this program?

A: This program assumes that the input string contains only alphabetic characters. If the input string includes special characters or numbers, the program may not provide accurate results.

Q: Can I optimize this program further?

A: This program serves as a basic implementation to find camel case without using library functions. Depending on your requirements, you can enhance the program by incorporating additional checks or validations.

Q: Are there any alternatives to camel case?

A: Yes, there are other naming conventions such as snake case (words separated by underscores) and kebab case (words separated by hyphens). The choice of naming convention depends on the programming language and coding standards being followed.

Q: How can I integrate this program into a larger codebase?

A: You can encapsulate the logic within a function and include the function in your codebase. This allows you to easily call the function whenever you need to check if a string follows the camel case convention.
