Small dynamic array (vector) implementation in C
- Note: this vector implementation currently only works with
inttype arrays
#include <stdio.h>
#include <stdlib.h>
#include "vector.h" // include the header
int main() {
vector test; // Create new vector
vector_init(&test, 0); // Initialize vector with 0 cells
vector_push(&test, 14); // Push some values
vector_push(&test, 52);
vector_push(&test, 46);
vector_push(&test, 12);
vector_insert(&test, 15, 0); // Insert value 15 before cell 0
vector_delete_at(&test, 1); // Delete value at cell 1 and shift cells after (in this case deletes 14)
test.at[1] = 23; // Set cell 1 to 23
printf("%d", test.at[2]); // Print value at cell 2
printf("%d", (int)test.size); // Print number of cells, size is type size_t, so we cast to int
vector_resize(&test, 50); // Resize vector to have 50 cells
vector_free(&test); // Deallocate vector memory
