在C言语编程中,对数字停止高效分类是数据处理中的一项基本技能。跟着数据量的增加,怎样疾速、正确地分类数字变得尤为重要。本文将具体介绍C言语中多少种高效分类数字的技能,帮助你轻松应对复杂数据处理挑衅。

一、利用数组停止分类

在C言语中,数组是一种非常实用的数据构造,可能用来存储跟分类数字。以下是一个利用数组对数字停止分类的示例:

#include <stdio.h>

void classifyNumbers(int *numbers, int size, int *positive, int *negative) {
    int i, countPositive = 0, countNegative = 0;
    for (i = 0; i < size; i++) {
        if (numbers[i] > 0) {
            positive[countPositive++] = numbers[i];
        } else if (numbers[i] < 0) {
            negative[countNegative++] = numbers[i];
        }
    }
}

int main() {
    int numbers[] = {3, -1, 4, -2, 5, -3};
    int size = sizeof(numbers) / sizeof(numbers[0]);
    int positive[size], negative[size];

    classifyNumbers(numbers, size, positive, negative);

    printf("Positive numbers: ");
    for (int i = 0; i < size; i++) {
        if (positive[i] != 0) {
            printf("%d ", positive[i]);
        }
    }
    printf("\nNegative numbers: ");
    for (int i = 0; i < size; i++) {
        if (negative[i] != 0) {
            printf("%d ", negative[i]);
        }
    }
    printf("\n");

    return 0;
}

二、利用排序算法停止分类

除了利用数组,还可能经由过程排序算法对数字停止分类。比方,疾速排序算法可能将数字按照从小到大年夜的次序陈列,从而实现分类。以下是一个利用疾速排序算法对数字停止分类的示例:

#include <stdio.h>

void swap(int *a, int *b) {
    int temp = *a;
    *a = *b;
    *b = temp;
}

int partition(int *numbers, int low, int high) {
    int pivot = numbers[high];
    int i = (low - 1);

    for (int j = low; j <= high - 1; j++) {
        if (numbers[j] < pivot) {
            i++;
            swap(&numbers[i], &numbers[j]);
        }
    }
    swap(&numbers[i + 1], &numbers[high]);
    return (i + 1);
}

void quickSort(int *numbers, int low, int high) {
    if (low < high) {
        int pi = partition(numbers, low, high);

        quickSort(numbers, low, pi - 1);
        quickSort(numbers, pi + 1, high);
    }
}

int main() {
    int numbers[] = {3, -1, 4, -2, 5, -3};
    int size = sizeof(numbers) / sizeof(numbers[0]);

    quickSort(numbers, 0, size - 1);

    printf("Sorted numbers: ");
    for (int i = 0; i < size; i++) {
        printf("%d ", numbers[i]);
    }
    printf("\n");

    return 0;
}

三、利用位运算停止分类

在某些情况下,可能利用位运算对数字停止分类。以下是一个利用位运算对数字停止分类的示例:

#include <stdio.h>

void classifyNumbersUsingBitwise(int *numbers, int size, int *positive, int *negative) {
    int i, countPositive = 0, countNegative = 0;
    for (i = 0; i < size; i++) {
        if (numbers[i] & 1) {
            negative[countNegative++] = numbers[i];
        } else {
            positive[countPositive++] = numbers[i];
        }
    }
}

int main() {
    int numbers[] = {3, -1, 4, -2, 5, -3};
    int size = sizeof(numbers) / sizeof(numbers[0]);
    int positive[size], negative[size];

    classifyNumbersUsingBitwise(numbers, size, positive, negative);

    printf("Positive numbers: ");
    for (int i = 0; i < size; i++) {
        if (positive[i] != 0) {
            printf("%d ", positive[i]);
        }
    }
    printf("\nNegative numbers: ");
    for (int i = 0; i < size; i++) {
        if (negative[i] != 0) {
            printf("%d ", negative[i]);
        }
    }
    printf("\n");

    return 0;
}
