c语言 合并两个有序数组

以下是C语言合并两个有序数组的代码示例：

#include <stdio.h>

void merge(int arr1[], int arr2[], int n1, int n2, int arr3[])
{
    int i = 0, j = 0, k = 0;

    // 合并两个数组
    while (i < n1 && j < n2) {
        if (arr1[i] < arr2[j])
            arr3[k++] = arr1[i++];
        else
            arr3[k++] = arr2[j++];
    }

    // 将剩余元素添加到合并后的数组中
    while (i < n1)
        arr3[k++] = arr1[i++];

    while (j < n2)
        arr3[k++] = arr2[j++];
}

int main()
{
    int arr1[] = {1, 3, 5, 7};
    int n1 = sizeof(arr1) / sizeof(arr1[0]);

    int arr2[] = {2, 4, 6, 8};
    int n2 = sizeof(arr2) / sizeof(arr2[0]);

    int arr3[n1 + n2];

    merge(arr1, arr2, n1, n2, arr3);

    printf("合并后的数组：\n");
    for (int i = 0; i < n1 + n2; i++)
        printf("%d ", arr3[i]);

    return 0;
}
