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

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);
