Example: Find Character Example in C

// Find Character Example
#include <stdio.h>
#include <string.h> // Required for strchr()

int main() {
    // Step 1: Declare a string and the character to find
    char text[] = "Programming is fun.";
    char charToFind1 = 'm';
    char charToFind2 = 'x'; // Character not in string

    // Step 2: Find the character using strchr()
    char *resultPtr1 = strchr(text, charToFind1);
    char *resultPtr2 = strchr(text, charToFind2);

    // Step 3: Print results based on whether the character was found
    if (resultPtr1 != NULL) {
        printf("Character '%c' found at position: %ld\n", charToFind1, resultPtr1 - text);
        printf("Substring from 'm': %s\n", resultPtr1);
    } else {
        printf("Character '%c' not found.\n", charToFind1);
    }

    if (resultPtr2 != NULL) {
        printf("Character '%c' found at position: %ld\n", charToFind2, resultPtr2 - text);
    } else {
        printf("Character '%c' not found.\n", charToFind2);
    }
    
    // Finding null terminator explicitly
    char *nullPtr = strchr(text, '\0');
    if (nullPtr != NULL) {
        printf("Null terminator found at position: %ld\n", nullPtr - text);
