How to define, input value and print srtuct array that include char * field in C

Answer 1

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

#define LEN 3
#define MAX_WORD_LEN 64

struct words_statistic 
{ 
    char *word; 
    int count_letters;
};

void print_struct(struct words_statistic ws[]);

int main(void)
{
    struct words_statistic ws[LEN];  
    char input[MAX_WORD_LEN];
    int i, word_len;
        
    for (i = 0; i < LEN; i++)
    {
        printf("Enter a word: ");
        gets(input);
        word_len = strlen(input);
        ws[i].word = (char *)malloc(word_len + 1);
        strcpy(ws[i].word, input);
        ws[i].count_letters = word_len;
    }
    
    print_struct(ws);
    
    for (i = 0; i < LEN; i++)
         free(ws[i].word);
    
    return 0;
}
void print_struct(struct words_statistic ws[])
{
    for (int i = 0; i < LEN; i++)
        printf("word: %s count: %d\n", ws[i].word, ws[i].count_letters);
    
}
