STRCAT problem

[Frusciante]

Hi!
I wanted to thank you a lot for the help given yesterday...
It`s so great to have people so well prepared trying to help you!

I have another problem: the bold line :
strcat want a pointer as argument, but probably i'm mistaking it ... can anybody help me?


#include <stdio.h>
#include <string.h>

main ()
{
int i;
char j;
char *ip;

for (i = 0; i < 10; i++)
{
ip=&j;
for (j = 0; j<3; j++)
{
FILE *fp;

char filename[17] ;

if (i == 0)
{
strcpy(filename, "injection-0");
if (j==0) strcat(filename,"_11.txt");
else if (j==1) strcat (filename,*ip);
else if (j==2) strcat (filename,"_12.txt");
}
if ((fp = fopen(filename, "w")) != NULL)
{
fprintf(fp, "mass_part mass_flow_part diam_part accretion surf_ID cel_ID temp vel_abs vel_nor vx vy vz Ax Ay Az Angle Wa Wb Wc WEAR\n");
fclose(fp);
}
}
}
}

I don't believe you have to dereference the pointer.
