One of the things which I miss while writing programs in C is a dictionary data structure. What's the most convenient way to implement one in C? I am not looking for performance, but ease of coding it from scratch. I don't want it to be generic either -- something like char* → int will do.
This C tutorial explains how to declare and use floating-point (float) variables with syntax and examples. Syntax. The syntax for declaring a float variable is: float variable_name1 [= value1]; Or the syntax for declaring multiple float variables is: float variable_name1 [= value1] [, variable_name2 [= value2], ... variable_name_n [= value_n]];

And we have arrays to group together a collection of data of the same data type. But in reality, we will not always have the luxury of having data of only one type.
delItem (dict, key); /* If we already have a item with this key, delete it. */. dict_t *d = malloc (sizeof (struct dict_t_struct)); d->key = malloc (strlen (key)+1); strcpy (d->key, key); d->value = value; d->next = *dict;
