如何在C中赋值一个子数组的值？

#include <stdio.h>

void assignSubArray(int source[], int destination[], int start, int length) {
    for (int i = 0; i < length; i++) {
        destination[start + i] = source[i];
    }
}

int main() {
    int source[] = {1, 2, 3, 4, 5};
    int destination[10] = {0}; // 假设目标数组足够大
    int start = 2; // 子数组开始的索引
    int length = 3; // 子数组的长度

    assignSubArray(source, destination, start, length);

    // 打印结果
    for (int i = 0; i < 10; i++) {
        printf("%d ", destination[i]);
    }
    return 0;
}

#include <stdio.h>
#include <string.h> // 包含memcpy函数的头文件

int main() {
    int source[] = {1, 2, 3, 4, 5};
    int destination[10] = {0}; // 假设目标数组足够大
    int start = 2; // 子数组开始的索引
    int length = 3; // 子数组的长度

    memcpy(destination + start, source, length * sizeof(int));

    // 打印结果
    for (int i = 0; i < 10; i++) {
        printf("%d ", destination[i]);
    }
    return 0;
}
