怎么让1，2,3 制表对齐标头
#include <stdio.h>
int main(void)
{
printf("hello world\n");
printf("hello world\n");
printf("hello world\n");
printf("hello world\n\n");
printf("\t1 welcome");
printf("\n\t2 well\t");
printf("\n\t3 good luck\t\n");
printf("hello world\n\v");
printf("hello world\n\v");

return 0;
}
[解决办法]

printf("1 welcome\t");
printf("\n2 well\t");
printf("\n3 good luck\t\n");
