各位大老 小弟想要把data存到txt里面但是不知道是哪里出错了下方是我打的代码及题目 拜托请各位帮我指正 感谢
#include<stdio.h>
#include<stdlib.h>
#include<time.h>
int main(void)
{
int i, num, black = 0, white = 0, red = 0;
int a, b;
FILE* fp;
fp = fopen("C:\Users\ASUS\Desktop\data.txt", "wb");
if (fp != NULL)
{
for (a = 0; a <= 1; a++)
{
fprintf(fp, "%d%d%d", black, white, red);
}
}
else
{ printf("file can't open");
exit(0);
}
fclose(fp);
srand(time(NULL));
for (i = 0; i < 10000; i++)
{
num = rand() % 10 + 1;
if (num <= 5)
++black;
if (5 < num && num <= 8)
++white;
if (8 < num)
++red;
}
printf("出現黑球的次數為%d次\n", black);
printf("出現白球的次數為%d次\n", white);
printf("出現紅球的次數為%d次\n", red);
fclose(fp);
system("pause");
return 0;
}
你这个应该用fread,fwrite读写结构体吧,写定义一个结构体,3个变量,然后读写结构体就可以了。
明天找我
请参考该代码进行改进:
/* Note:Your choice is C IDE */
#include "stdio.h"
struct SNAKE
{
int direction;
int life;
int node;
int level;
int score;
}snake;
struct FOOD{
int x;
int y;
int yes;
}food;
void main()
{
FILE *fp;
snake.direction=1;
snake.life=1;
snake.node=3;
snake.level=1;
snake.score=0;
food.x=100;
food.y=200;
food.yes=1;
fp = fopen("d:\\snake.dat","wb+");
if(fp==NULL){
printf("can not open file.\n");
exit(0);
}
fwrite(&snake,sizeof(struct SNAKE),1,fp);
fwrite(&food,sizeof(struct FOOD),1,fp);
fclose(fp);
}
