#include <stdio.h>

int sayLove()

{

    printf("%s\n","小明在慕课网上学习");

    return 0;

}

int Love(int n)

{

    printf("小明在慕课网上已经参与学习了%d门课程"，n);

    return 0;

}

int main()

{

    sayLove();

    Love(5);

    return 0;

}

为什么运行是这样的

/249/5442/CSM6/hello.c: In function 'Love':
/249/5442/CSM6/hello.c:10:5: error: stray '\357' in program
    printf("小明在慕课网上已经参与学习了%d门课程"，n);
    ^
/249/5442/CSM6/hello.c:10:5: error: stray '\274' in program
/249/5442/CSM6/hello.c:10:5: error: stray '\214' in program
/249/5442/CSM6/hello.c:10:70: error: expected ')' before 'n'
    printf("小明在慕课网上已经参与学习了%d门课程"，n);
