竞赛中打表操作

#include<stdio.h>
#include<stdlib.h>

int main()
{
    int i;
    freopen("1.txt","w",stdout);
    printf("a[]={");
    for(i=0;i<100;i++)
        if(i%10==0)
            printf("\n");
        else
            printf("%d,",i);
    printf("};");
    return 0;
}

可以生成一个1.txt文档

上述程序会有以下结果

a[]={
1,2,3,4,5,6,7,8,9,
11,12,13,14,15,16,17,18,19,
21,22,23,24,25,26,27,28,29,
31,32,33,34,35,36,37,38,39,
41,42,43,44,45,46,47,48,49,
51,52,53,54,55,56,57,58,59,
61,62,63,64,65,66,67,68,69,
71,72,73,74,75,76,77,78,79,
81,82,83,84,85,86,87,88,89,
91,92,93,94,95,96,97,98,99,};

只需把最后一个逗号删掉即可

a[]={
1,2,3,4,5,6,7,8,9,
11,12,13,14,15,16,17,18,19,
21,22,23,24,25,26,27,28,29,
31,32,33,34,35,36,37,38,39,
41,42,43,44,45,46,47,48,49,
51,52,53,54,55,56,57,58,59,
61,62,63,64,65,66,67,68,69,
71,72,73,74,75,76,77,78,79,
81,82,83,84,85,86,87,88,89,
91,92,93,94,95,96,97,98,99};
