请教大虾下面程序中的错误(用VC 编译C 时出错):

#include <stdio.h>

main()
{
    int count;

    printf("This is%n a test program\n",&count);
    printf("count = %d\n",count);
   
}

printf("This is%p a test program\n",&count);

#include <stdio.h>

main()
{
    int count;

    printf("This is%n a test program\n",&count);
    printf("count = %d\n",count);
    return 0;
   
}
