Dyna

generic dynamic array in C supporting various data types such as int, char, float, and char* (strings). (Header Only btw).

Features

• Dynamically resizes on demand
• Type-safe via macro-based initialization
• Supports any data type
• Easy printing with format specifiers

Usage

Initialization

Use the DYNA_INIT(Type) macro to define a dynamic array type:

DYNA_INIT(int) Dyna;
Dyna dyna = {0};
dyna.start = malloc(DYNA_INITIAL_CAP * sizeof(int));
dyna.capacity = DYNA_INITIAL_CAP;
dyna.size = sizeof(int);

Append Elements

Use dyna_append(&array, value) to add elements dynamically:

for (int i = 0; i < 50; ++i) {
    dyna_append(&dyna, i);
}

Print Elements

Use dyna_print(&array, format) to print the array:

dyna_print(&dyna, "%i");  // For ints

Free Memory

Don't forget to free the memory:

dyna_free(&dyna);

Examples

Integers

DYNA_INIT(int) Dyna;
Dyna dyna = {0};
dyna.start = malloc(DYNA_INITIAL_CAP * sizeof(int));
dyna.capacity = DYNA_INITIAL_CAP;
dyna.size = sizeof(int);

for (int i = 0; i < 50; ++i) dyna_append(&dyna, i);

dyna_print(&dyna, "%i");
dyna_free(&dyna);

Characters

DYNA_INIT(char) DynaChar;
DynaChar dynac = {0};
dynac.start = malloc(DYNA_INITIAL_CAP * sizeof(char));
dynac.capacity = DYNA_INITIAL_CAP;
dynac.size = sizeof(char);

for (int i = 0; i < 26; ++i) dyna_append(&dynac, 'a' + i);

dyna_print(&dynac, "'%c'");
dyna_free(&dynac);

Floats

DYNA_INIT(float) DynaFloat;
DynaFloat dynaf = {0};
dynaf.start = malloc(DYNA_INITIAL_CAP * sizeof(float));
dynaf.capacity = DYNA_INITIAL_CAP;
dynaf.size = sizeof(float);

for (int i = 0; i < 10; ++i) dyna_append(&dynaf, i + 0.5f);

dyna_print(&dynaf, "%f");
dyna_free(&dynaf);

Strings

DYNA_INIT(char*) DynaStr;
DynaStr dynas = {0};
dynas.start = malloc(DYNA_INITIAL_CAP * sizeof(char*));
dynas.capacity = DYNA_INITIAL_CAP;
dynas.size = sizeof(char*);

for (int i = 0; i < 10; ++i) dyna_append(&dynas, "Hello There");

dyna_print(&dynas, "\"%s\"");
dyna_free(&dynas);
