cstructs

IntegerArray, Double Array, StringArray and String2DArray Data Structures For C.

Purpose

Provide essential data structure to simplify the development of programs in c.

How to use the library

//clone the library and put it in your project

//You will need to import the header files

#include "cstructs/array.h"

#include "cstructs/data.h"

#include "cstructs/stats.h"

// creates a dynamic IntegerArray numbers

struct IntegerArray* numbers = newIntegerArray();

//adds numbers to the array

addToIntegerArray(numbers, 12);
addToIntegerArray(numbers, 23);
addToIntegerArray(numbers, 42);

//prints the array to the console

printIntegerArray(numbers);

//gets the value of the array at the given index

const int id = 2;
const int* i = getIntegerValue(numbers, id);
printf("Integer value at index 2 is %d\n",*i);

printf("Setting value 45 at index 2\n");
setIntegerValue(numbers,45,2);
printIntegerArray(numbers);

printf("Reversing the array\n");
reverseIntegerArray(numbers);
printIntegerArray(numbers);

//example 2

struct IntegerArray* numbers2 = newIntegerArray();

//adds all the numbers provided in the string

addAllToIntegerArray(numbers2,"4,5,7,8,9,0");
printIntegerArray(numbers2);

//computes the correlation coefficient

double c =  corrIntegerArray(numbers, numbers2);
printf("Correlation %.2f\n",c);

//frees the memory

freeIntegerArray(numbers);
freeIntegerArray(numbers2);

//creates a double array

struct DoubleArray* numbers = newDoubleArray();

//adds the data to the array

addToDoubleArray(numbers, 0.2);
addToDoubleArray(numbers, 2.8);
addToDoubleArray(numbers, 3.2);
addToDoubleArray(numbers,34);

//creates another array

struct DoubleArray* numbers2 = newDoubleArray();

//adds all the numbers in the array

addAllToDoubleArray(numbers2, "34.3,6,3.5");

printf("Array 1");
printDoubleArray(numbers);
printf("Array 2");
printDoubleArray(numbers2);

printf("correlation %.2f\n",corrDoubleArray(numbers, numbers2));
printf("Sum of two arrays ");
struct DoubleArray* sum = addDoubleArrays(numbers,numbers2);
printDoubleArray(sum);

freeDoubleArray(sum);
freeDoubleArray(numbers);
freeDoubleArray(numbers2);

//imports data from a csv

struct String2DArray* trainData = importData("data.csv",',',5);

//filters the data with the given index value

struct String2DArray* part = filterString2DArray(trainData, "ID2136364");

//prints thee 2D array

printString2DArray(part);

//creates an array of strings

struct StringArray *s = newStringArray();

//populates the array

addToStringArray(s, "randu");
addToStringArray(s, "katana");
addToStringArray(s, "karisa");
changeStringArray(s, "Daga", 1);

//prints the array

printStringArray(s);
printf("%d\n",*getStringArraySize(s));
freeStringArray(s);
