c - How to read a file of names into an array -

i need help reading in list of names , storing them string. allocated memory strings, need help reading them , storing them in. here info , code written. need help insert_data function.

#include <string.h> #include <stdio.h> #include <stdlib.h> #define max_string_len 25 void insert_data(char **strings, const char *filename, int size); void allocate(char ***strings, int size); int main(int argc, char* argv[]){ if(argc != 4){ printf("wrong number of args"); } char **pointer; int size = atoi(argv[1]); allocate(&pointer, size); insert_data(pointer, argv[2], size); } void allocate(char ***strings, int size){ int i; *strings = (char**) malloc(sizeof(char**) * size); for( = 0; < size; i++) { (*strings)[i] = malloc(sizeof(char) * max_string_len); } }

this function need help with:

void insert_data(char **strings, const char *filename, int size){ file *input; input = fopen(filename, "r"); int i; (i = 0; < size; i++){ fscanf(input,"%s", (*strings)[i]); } fclose(input); }

here list reading in:
