How to declare and use array of pointers in main() to array of pointers to strings in a struct with C

Answer 1

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

#define LEN 3

typedef struct
{
    char *string_array[LEN];
} programming;
  
int main(void)
{
    int i;
    programming pl;
    
    pl.string_array[0] = "c";
    pl.string_array[1] = "c++";
    pl.string_array[2] = "java";
    
    char **p = (char **)malloc(sizeof(char *) * LEN);
    
    for (i = 0; i < LEN; i++) 
        p[i] = pl.string_array[i];
    
    for (i = 0; i < LEN; i++) 
        printf("%d %s\n", i, p[i]);
        
    free(p);

    return 0;
}
