Programming

I am struck in the code of handling multiple files reading and appending it into a variable.

My First file's entire content I have concatenated using strcat(<char pointer>,char array)

In the Second file I extract using strtstr() function and below is the code.

Code:

if( fp2 != NULL){
            while(fgets(a, sizeof a, fp2) != NULL){
               if(strstr(a,"-----BEGIN") != NULL){
                 printf("%s",a);  // For selecting this line too...
                 while((i=fgetc(fp2)) != EOF){
                   printf("%c",i);
               //      strcat(con,i);
                 }
               }
            }
          }

I get error Like Segmentation problem while processing the line strcat in the code above.

And after this in the third file, if I use the strcat() to append the contents it's too not working....

I declared the variables like,

Code:

FILE *fp2;
char a[100],*con,i;
con =(char*)malloc(1000);

Please help !

Please use code tags, thanks!

You cannot strcat a character. You strcat entire strings. That will cause a segmentation fault.

So use fgets instead of fgetc there.

Also: What code gets run here depends on the content of the files. You have not shown any content from your files. Please do so.

ya. That's true ! Thanks for explaining me correctly !
