求大神指導!!C語言如何獲取txt文檔數據的個數?

# include & ltstdio.h & gt

void main()

{

int count=0,temp

FILE * fp

fp = fopen("test1.txt "," r ");

而(!Feof(FP))//這個函數的feof決定了文件指針是否到達文件的末尾。

{

fscanf(fp," %d\n ",& amptemp);//fscanf如何使用這個函數可以在百科名片中了解。

printf("%d\n ",temp);

count++;

}

fclose(FP);

Printf("***有%d個數據",count);

}

修改程序,向文本中輸入數據,並從文本中計算輸出數據的數量

# include & ltstdio.h & gt

void main()

{

int count=0,temp

FILE * fp

fp = fopen("test1.txt "," w ");

while(scanf("%d ",& amp溫度))

{

fprintf(fp," %d\n ",temp);

}

fclose(FP);

fp =fopen("test1.txt "," r ");

而(!feof(fp))

{

fscanf(fp," %d\n ",& amptemp);

printf("%d\n ",temp);

count++;

}

fclose(FP);

Printf("***有%d個數據",count);

}
