函数要先声明才行

#include"math.h"
#include"string.h"

int scanline();
int outline();
void main()
{
	int n;
	i=0;
	scanline();
	printf("Enter data file name:");
	scanf("%s",fname);
	fp=fopen(fname,"w");
	fprintf(fp,"%d\n",i);
	for(n=1;n<=i;n++)
	{fprintf(fp,"%f,%f,%f\n",xs[n],ys[n],zs[n]);
	fprintf(fp,"%f,%f,%f\n",xe[n],ye[n],ze[n]);
	}
	fclose(fp);
}
int scanline()
{
