利用C语言产生随机数

#include "stdio.h" 
#include "stdlib.h" 
#include "time.h" 
void main() 
{ 
	int i,t; 
	FILE *fp=fopen("G:\\data.txt","w"); 
	srand( (unsigned)time(NULL) ); 
	for( i=0; i<2880;i++)
		{ 
			printf( "Random number #%d: %d\n", i, t=rand()%2 ); 
			fprintf(fp,"%3d",t); 
		} 
	fclose(fp); 
}
