// Basic Strings Revision
// A string in C is an array of char which ends in a '/0'
// The standard library which has a lot of useful string functions is <string.h>
// You can read a string from terminal by using fgets() function 
// Eg. string[] = "hello" is:
// string[0] = 'h'
// string[1] = 'e'
// string[2] = '\0'
// string[3] = 'l'
// string[4] = '\0'
// string[5] = '\n'
// string[6] = '\0'
// 


#include <stdio.h>

#define MAX 100

int main (void) {
    
    char string_array[MAX];
    printf("Enter a word: ");
    //read the string from terminal into string_array[] using fgets()
    fgets(string_array, MAX, stdin);
    
    // Let's say the word is: hello
    // I can print out the first character:
    printf("The first character of the word is: %c\n", string_array[0]);
    //I can change it up:
    string_array[4] = 'g';
    //This means the word is now "hellg"
    printf("%s\n", string_array);
    
    //I can truncate it to my heart's content:
    string_array[4] = '\0';
    //This means the word is now "hell" 
    printf("%s\n", string_array);
    
    string_array[2] = '\0';
    printf("%s\n", string_array);

    return 0;
