2 stringi birleştiremedim :(

 
  #include <stdio.h> 
  #include <stdlib.h> 
  #include <string.h> 
   
  struct deneme 
  { 
          char *filename; 
  } *dene; 
   
  int main () 
  { 
          dene = malloc (sizeof(struct deneme)); 
          dene->filename = (char*)malloc(200*sizeof(char)); 
          char *path=(char*)malloc(sizeof(char)*250); 
          path = "/bin/"; 
          printf("Enter a file name: "); 
          fgets(dene->filename,200,stdin); 
          printf("filename:%s",dene->filename); 
          strcat(path,dene->filename); 
          printf("birlestirilmiş: %s\n",path); 
   
          return 0; 
  }
