用fopen动态创建多个文件

Question

如下，我想写个for循环，动态创建10个txt文件，如何把这个i值，动态传入？我是新手，望指教！

int main(void)
{
    for (int i = 0; i < 10; i++)
    {
        FILE *fp = NULL;
        //fp = fopen("C:\\Users\\Dell\\Desktop\\" + i + ".txt", "a");
        //fputs("第个" + i + "文件"，fp);
        fclose(fp);
    }

    return 0;
}

#include<stdio.h>
int main(void)
{
    for (int i = 0; i < 10; i++)
    {
        FILE *fp = NULL;
        char filename[1024] = {0};
        sprintf(filename,"C:\\Users\\Dell\\Desktop\\%d.txt",i);
        fp = fopen(filename, "a");
        fprintf(fp,"第个%d文件",i);
        fclose(fp);
    }
    return 0;
