How to find the largest and the smallest word in a string with C

Answer 1

#include <stdio.h> 
#include <string.h> 
#include <ctype.h>
 
void find_largest_and_smallest_word_in_string(char string[], char min[], char max[]) {
    char word[16];
    int j = 0, flag = 0;
  
    for (int i = 0; i < strlen(string); i++) {
        while (i < strlen(string) && !isspace(string[i]) && isalnum(string[i])) {
            word[j++] = string[i++];
        }
  
        if (j != 0) {
            word[j] = '\0';
  
            if (!flag) {
                flag = !flag;
                strcpy(max, word);
                strcpy(min, word);
            }
  
            if (strlen(word) > strlen(max)) {
                strcpy(max, word);
            }
  
            if (strlen(word) < strlen(min)) {
                strcpy(min, word);
            }
  
            j = 0;
        }
    }
 }

int main(void)
{   
    char string[] = "c cpp c# python java";
    char min[16] = "", max[16] = "";
    
    find_largest_and_smallest_word_in_string(string, min, max);
    
    printf("The largest word is: %s\n", max);
    printf("The smallest word is: %s\n", min);
      
    return 0;
}

   
         
/*
run:
      
The largest word is: python
The smallest word is: c
