帮我写在C++中把多个一维数组合并为一个一维数组的代码

好的，以下是可以将多个一维数组合并为一个一维数组的C代码：

#include <stdio.h>

void mergeArrays(int arr1[], int size1, int arr2[], int size2, int mergedArr[]) {
    int i = 0, j = 0, k = 0;

    // Merge elements of two arrays into one array
    while (i < size1 && j < size2) {
        if (arr1[i] < arr2[j]) {
            mergedArr[k++] = arr1[i++];
        }
        else {
            mergedArr[k++] = arr2[j++];
        }
    }

    // Copy remaining elements of arr1[] if any
    while (i < size1) {
        mergedArr[k++] = arr1[i++];
    }

    // Copy remaining elements of arr2[] if any
    while (j < size2) {
        mergedArr[k++] = arr2[j++];
    }
}

int main() {
    // Define two arrays to be merged
    int arr1[] = { 1, 2, 3, 4 };
    int arr2[] = { 5, 6, 7, 8 };

    // Determine the size of each array
    int size1 = sizeof(arr1) / sizeof(arr1[0]);
    int size2 = sizeof(arr2) / sizeof(arr2[0]);

    // Determine size of merged array
    int mergedSize = size1 + size2;
   
    // Define merged array
    int mergedArr[mergedSize];

    // Merge two arrays
    mergeArrays(arr1, size1, arr2, size2, mergedArr);

    // Print the merged array
    for (int i = 0; i < mergedSize; i++) {
        printf("%d ", mergedArr[i]);
    }

    return 0;
}

希望能对您有所帮助。
