在C中打印数字行

Question

我尝试读取文件，然后用它们打印数字行。但我不知道如何在同一时间打印lorem ipsum。因为我不知道在C

这里打印功能多是我的代码：

#include <stdio.h> 
#include <stdlib.h> 
main(){ 

int c; 
int b=1; 
//int a[5000]; Shall I use this or any ideas without them? 

FILE *xfile; 
xfile = fopen("loremipsum.txt", "r"); 

while((c=getc(xfile)) != EOF){ 
if(c == '\n'){ 
printf("%d\n", b); /*STUCK IN THERE... HOW TO PRINT LOREM IPSUM WITH NUMBER LINES?*/ 
//putchar(a); 
b++; 
} 
} 

} 

我Lorem存有：

 
Lorem ipsum dolor sit amet, consectetur adipiscing elit. 
Donec vitae quam non risus consectetur aliquet sed rhoncus purus. 
Fusce vitae lorem a dui elementum condimentum id id odio. 
Quisque eu felis eu diam facilisis mollis sit amet id augue. 


Duis lacinia velit et lorem ullamcorper iaculis. 
Duis malesuada lacus quis quam congue nec euismod ante condimentum. 
Donec dignissim augue vitae nulla dapibus vehicula. 

我想要什么：

 
1. Lorem ipsum dolor sit amet, consectetur adipiscing elit. 
2. Donec vitae quam non risus consectetur aliquet sed rhoncus purus. 
3. Fusce vitae lorem a dui elementum condimentum id id odio. 
4. Quisque eu felis eu diam facilisis mollis sit amet id augue. 


5. Duis lacinia velit et lorem ullamcorper iaculis. 
6. Duis malesuada lacus quis quam congue nec euismod ante condimentum. 
7. Donec dignissim augue vitae nulla dapibus vehicula. 

Answer 1

那么使用fgets代替读取一个字符的整行代码怎么样呢？

char input[256]; 
int line = 1; 

while (fgets(input, sizeof(input), xfile) != NULL) 
{ 
    printf("%2d. %s", line++, input); 
}

虽然将最后一个字符保留在变量中可能会很有用，但它有很好的方法。

int c; 
int b = 1; 
int prec = '\n'; 

while ((c = getc (xfile)) != EOF) { 
     if (prec == '\n') 
       printf ("%d. ", b++); 

     putchar (c); 
     prec = c; 
}
