I create an array "sequence", he could read from the storage structure. TXT "number after each of the router. The router number for" nb_input ", we can choose the number range is "nb_output".
For example, if the TXT file like this:
Router1 1, 3, 4,
In the sequence of the corresponding position will be assigned to 1=& gt; The sequence [0] [0]=1, the sequence [0], [2]=1 sequence [0] [3]=1
My "structure. TXT" goes like this:

My code is as follows. Nb_input=6, nb_output=16 has been pre-defined

 
/* read structure. TXT */
#include  
#include  
#include  
#include  
#include  
# define BUFFER_SIZE 1024 
# define WHITESPACE 0 x20

The sequence [I] [j]=0; 
} 
} 
FStruct=fopen (" C:/Users/13383/Desktop/creater_noc/structure. TXT ", "rt");

{

{

Memset (s, 0, sizeof (s)); 
}

{

Memset (s, 0, sizeof (s)); 
If (b>=1 & amp; & C>

Sequence [1 b] [c - 1]=1; 
} 
//printf (" b=% d, c=% d \ n ", b, c); 
} 
S [k]=line [I]; 
for(; The line [I + 1] <='9' & amp; & Line [I + 1] & gt;='0') 
{
i++; 
K++; 
S [k]=line [I]; 
} 
If (line [I] - k - 1=='r') 
{
Start=1; 
} 
Else if (line [I + 1)=='\ n') 
{
C=atoi (s); 
Memset (s, 0, sizeof (s)); 
If (b>=1 & amp; & C> 
=1){
Sequence [1 b] [c - 1]=1; 
} 
//printf (" b=% d, c=% d \ n ", b, c); 
continue; 
} 
Else if (line [I + 1)==(EOF) 
{
C=atoi (s); 
Memset (s, 0, sizeof (s)); 
If (b>=1 & amp; & C> 
=1){
Sequence [1 b] [c - 1]=1; 
} 
//printf (" b=% d, c=% d \ n ", b, c); 
continue; 
} 
The else 
{
Start=2; 
} 
//k++; 

} 
Else if (start==1 | | start==2) 
{
K=0; 
} 
} 
} 
} 
} 

I found that I always read the last line is wrong, may be because of EOF, excuse me, everyone is my code problem?

CodePudding user response:

 else if (line [I + 1)==EOF | | line [I + 1)=='\ 0')//add a is equal to '\ 0' judgment 

The end of the file may be '\ 0'
