template in c for vector
Just drop the vector.h header file in your project.
Or just download it :
wget https://raw.githubusercontent.com/ThisisYoYoDev/C-vector-template/main/include/vector.hCREATE_VECTOR allow you to initialize the structure of your vector.
Example:
typedef struct {
int x;
int y;
} point_t;
CREATE_VECTOR(point, point_t);point_t = type of the vector
point = name of the struct
The type of the vector here is vector_point_t
VECTOR_INIT allow you to initialize the variable of the vector and to allocate it. VECTOR_INIT has optional parameters either you specify a size of your choice or the size will be that of the BUFFER (128).
Example:
void example_vector(void)
{
VECTOR_INIT(point, v1);
VECTOR_INIT(point, v2, 50);
}point = name of the struct (declare in CREATE_VECTOR) v1 | v2 = created variable 50 = capacity of the vector
VECTOR_RESERVE aKa VECTOR_RESIZE VECTOR_RESERVE allow you to realloc your vector for given size.
Example:
void example_vector(void)
{
VECTOR_INIT(point, v1);
VECTOR_RESERVE(v1, 50);
}v1 = variable of the vector 50 = add 50 elements to the capacity of the vector
VECTOR_PUSH_BACK: Push a value at the end of a vector. VECTOR_PUSH_BACK can take one or more element to add in the vector.
Example:
void example_vector(void)
{
VECTOR_INIT(point, v1);
VECTOR_PUSH_BACK(v1, (point_t){1, 1});
/* or */
VECTOR_PUSH_BACK(v1, (point_t){10, 10}, (point_t){5, 5}, (point_t){-999, 999});
}VECTOR_PUSH_AT: Push a value at a given index. Same usage that VECTOR_PUSH_BACK but at a given index.
Example:
void example_vector(void)
{
VECTOR_INIT(point, v1);
VECTOR_PUSH_BACK(v1, (point_t){1, 1});
/* or */
VECTOR_PUSH_BACK(v1, (point_t){10, 10}, (point_t){5, 5}, (point_t){-999, 999});
VECTOR_PUSH_AT(v1, 0, (point_t){1, 1});
/* or */
VECTOR_PUSH_AT(v1, 3, (point_t){10, 10}, (point_t){5, 5}, (point_t){-999, 999});
}3 = index to push the element
VECTOR_PUSH_FRONT: Push a value at the front of a vector Same usage that VECTOR_PUSH_BACK.
Example:
void example_vector(void)
{
VECTOR_INIT(point, v1);
VECTOR_PUSH_FRONT(v1, (point_t){1, 1});
/* or */
VECTOR_PUSH_FRONT(v1, (point_t){10, 10}, (point_t){5, 5}, (point_t){-999, 999});
}VECTOR_POP_BACK: Pop a value at the end of a vector.
Example:
void example_vector(void)
{
VECTOR_INIT(point, v1);
VECTOR_PUSH_FRONT(v1, (point_t){1, 1});
VECTOR_POP_BACK(v1);
}VECTOR_POP_FRONT: Pop a value at the front of a vector.
Example:
void example_vector(void)
{
VECTOR_INIT(point, v1);
VECTOR_PUSH_FRONT(v1, (point_t){1, 1});
VECTOR_POP_FRONT(v1);
}VECTOR_POP_AT: Pop a value at a given index.
Example:
void example_vector(void)
{
VECTOR_INIT(point, v1);
VECTOR_PUSH_FRONT(v1, (point_t){1, 1});
VECTOR_PUSH_FRONT(v1, (point_t){1, 1});
VECTOR_PUSH_FRONT(v1, (point_t){1, 1});
VECTOR_PUSH_FRONT(v1, (point_t){1, 1});
VECTOR_POP_AT(v1, 2);
}2 = index to pop
VECTOR_AT: Get a value at a given index.
Example:
void example_vector(void)
{
