C语言指针实现两个有序数组的合并排序

#include <stdio.h>

void printIncreasingOrder(int *a, int *b, int size) {
    int i = 0, j = 0, k = 0;
    int c[20];
    while (i < size && j < size) {
        if (a[i] < b[j]) {
            c[k++] = a[i++];
        } else {
            c[k++] = b[j++];
        }
    }
    while (i < size) {
        c[k++] = a[i++];
    }
    while (j < size) {
        c[k++] = b[j++];
    }
    printf('The elements in increasing order: ');
    for (int m = 0; m < 2 * size; m++) {
        printf('%d ', c[m]);
    }
    printf('
');
}
