c函数fprintf变量文件指针

Question

I have multiple file pointers. During a loop I want to print something into a certain file. Which file depends on the loop pass.

fprintf(stream,"v   t \n");

With "stream" I choose the file. Is it possible to pass a certain array element as stream?

For example:

FILE *vx;
FILE *vy;
FILE *vz;

vx=fopen("vx.txt","w");
vy=fopen("vy.txt","w"); 
vz=fopen("vz.txt","w");

pointer[]={vx,vy,vz};

while(n<4)
{
    funck(n, k, v, w, h);
    fprintf(pointer[n-1],"v t \n");
    n+=1;
}

Is it a possible to save file pointer in an array? Is this a good solution?

Answer 1

Yes, it's possible, as long as you pass a variable of type FILE * to fprintf() .

The array type must be of type FILE* , since the array store pointers to a referenced FILE object ( FILE* ).

If you were using pointers, the pointer's type must have been be FILE** , since it's a pointer( * ) to a referenced FILE object ( FILE* ).

Answer 2

Yes, it is possible. Type your array with FILE *.
