Check if String Contains a Character in C

To check if a string contains a specific character in C, you can use the strchr function from the C standard library. Here are the steps to do this:

1. Include the Necessary Header File:

2. Include the <string.h> header file to use the strchr function.

3. Use the strchr Function:

4. Call the strchr function with the string and the character you want to search for as its arguments.
5. If the function returns a non-NULL value, the character is present in the string; otherwise, it's not.

Here's an example of how you can use the strchr function to check if a string contains a specific character:

#include <stdio.h>
#include <string.h>

int main() {
    char str[] = "Hello, World!";
    char ch = 'o';

    if (strchr(str, ch) != NULL) {
        printf("The character '%c' is present in the string.\n", ch);
    } else {
        printf("The character '%c' is not present in the string.\n", ch);
    }

    return 0;
}

In this example, the str array contains the string "Hello, World!" and we want to check if it contains the character 'o'. The strchr function is used to perform this check.
