我想知道如果这个程序全天候运行,操作系统会过载吗?

没有语法错误,但我想知道如果这个程序全天候运行,操作系统会过载吗?如何测试记忆力?我的意思是有多少未使用的变量?我在visual studio中编写了这段代码,可以进行一些更改。

struct video{
    char category[10];
    long long int rating;
};

int main(void){
    srand((unsigned int)time(0));
    while (1) {
        struct video* gaming = (struct video*) malloc(sizeof(*gaming));
        struct video* music = (struct video*) malloc(sizeof(*music));
        struct video* vlog = (struct video*) malloc(sizeof(*vlog));

        strcpy_s(gaming->category, 7, "Gaming");
        strcpy_s(music->category, 6, "Music");
        strcpy_s(vlog->category, 5, "Vlog");

        gaming->rating = rand() % 10000000 + 1;
        music->rating = rand() % 10000000 + 1;
        vlog->rating = rand() % 10000000 + 1;

        printf("Category: %s Rating: %lld",gaming->category,gaming->rating);
        printf("Category: %s Rating: %lld",music->category,music->rating);
        printf("Category: %s Rating: %lld",vlog->category,vlog->rating);

        Sleep(3000);
        system("cls");

        free(gaming);
        free(music);
        free(vlog);
    }
}
