求画c语言ns图 程序如下
#include <stdio.h>
int main( )
{
int i , n;
unsigned long a[40];
FILE *fp = fopen("data.txt", "w");
a[0] = 3;
a[1] = 5;
for(i = 2; i < 40; i++)
a[i] = a[i-2] + a[i-1];
system("cls");
for(i = 1; i <= 40; i++)
{
printf("%-10ld", a[i-1]);
fprintf(fp,"%-10ld", a[i-1]);
if(i%10 == 0)
{
printf("\n");
fprintf(fp, "\n");
}
}
n = 0;
printf("\n\n\n");
fprintf(fp, "\n\n\n");
for(i = 0; i < 40; i++)
{
if(a[i]%3 == 0)
{
printf("%-10ld", a[i]);
fprintf(fp,"%-10ld", a[i]);
n++;
if(n%10 == 0)
{
printf("\n");
fprintf(fp, "\n");
}
}
}
return 0;
}
