C Programming project related help

Hello, I've got 2 methods to do as the following

//
// It returns in *name and *value the name and value that correspond to
// the ith entry. It will return 1 if successful, or 0 otherwise.
//
int rtable_get_ith(RESIZABLE_TABLE * table, int ith, char ** name, void ** value) {
   return 0;
}

//
// It removes the ith entry from the table. The entries after the entry removed are
// moved downwards to use the empty space. Also the name/value strings are freed.
//
int rtable_remove_ith(RESIZABLE_TABLE * table, int ith) {
   return 0;
}

For example, if I have a table like -

1) Mat 298 Vine Street

2) Jeff 998 Vine Street

3) Sun 234 Vine Street

Using the methods should return the appropriate answer. (table has 2 properties, name which is the name of the person and value which is address.

(This is the way I am doing it currently) -

int rtable_get_ith(RESIZABLE_TABLE * table, int ith, char ** name, void ** value) {
if((strcmp(table->array[ith].name, &name) == 0) && (strcmp(table->array[ith].value, &value) ==
0)) {
return 1;
}
return 0;
}

Explanation / Answer

What you are doing for rtable_get_ith is right, the function is

int rtable_get_ith(RESIZABLE_TABLE * table, int ith, char ** name, void ** value)

{

if((strcmp(table->array[ith].name, &name) == 0) && (strcmp(table->array[ith].value, &value) ==
0))

{

return 1;

}

return 0;

}

int rtable_remove_ith(RESIZABLE_TABLE * table, int ith)

{

free(table->array[ith].name);

free(table->array[ith].value);

//All entries before i are moved downwards

int j;

for(j=0;j<i;j++)

{

//Shifting downwards

table->array[ith-j].name = table->arrya[ith-j-1].name;

table->array[ith-j].value = table->array[ith-j-1].value;

}

return 0;

}
