#CV: Generic Dynamic arrays in C
CV is a standalone and lightweight library written in C, for C developers, aiming at emulating the behavior of C++'s vector. It also makes available the most used functions from the algorithm library such as find, copy, count ...
###Types
For convenience the following types are already declared:
| Contained Type | Type name |
|---|---|
| char | String |
| short | VectorShort |
| int | VectorInt |
| float | VectorFloat |
| double | VectorDouble |
###Usage
// Declare a vector of int
VectorInt vec;
// Other variables used for this test
int tab[] = {5,4,3,2,1,0};
int find_pos;
int value;
// Initialize the vector's attributes
vec_init(&vec);
// Push some values
for (unsigned int i = 0; i < 10; ++i)
vec_push_back(&vec, i);
// find the position of the value 6 in vec (-1 if not found)
find_pos = vec_find(&vec, 6);
// insert the tab at the position of 6
vec_insert_array(&vec, tab, sizeof(tab) / sizeof(*tab), find_pos);
// insert the value -1 at the beginning of vec
vec_insert(&vec, -1, 0);
// delete the last value
vec_erase(&vec, vec_size(&vec) - 1);
// Iterate over vec and print its content
vec_foreach(&vec, value)
printf("%d ", value);
printf("\n");
// Delete the vector and free its memory
vec_delete(&vec);Outputs:
-1 0 1 2 3 4 5 5 4 3 2 1 0 6 7 8
Vec(Person) people;
Person person;
int jack_pos;
vec_init(&people);
vec_push_back(&people, ((Person){.name = "willie", .age = 10}));
vec_push_back(&people, ((Person){.name = "Henry", .age = 35}));
vec_push_back(&people, ((Person){.name = "Bessie", .age = 15}));
vec_push_back(&people, ((Person){.name = "Stephanie", .age = 64}));
vec_foreach(&people, person)
printf("Hi, I'm %s and I'm %d years old\n", person.name, person.age);
vec_insert(&people, ((Person){.name = "Jack", .age = 75}), 2);
jack_pos = vec_find_if(&people, is_jack);
printf("\nHi, I'm %s and I'm inserted between %s and %s\n",
vec_at(&people, jack_pos).name,
vec_prev(&people, jack_pos).name,
vec_next(&people, jack_pos).name);
vec_delete(&people);Outputs:
Hi, I'm willie and I'm 10 years old
Hi, I'm Henry and I'm 35 years old
Hi, I'm Bessie and I'm 15 years old
Hi, I'm Stephanie and I'm 64 years old
Hi, I'm Jack and I'm inserted between Henry and Bessie
