For each of the code snippet given below, identify the error and then write code after fixing the error.

Given code is the simulation of grep -v command. -v prints all lines that do not match a specific

pattern.

void grep_inverse(char *filename, char *str)

{

FILE *fp;

char buf[buff_size];

fp = fopen(filename, "r");

if(!fp) {

       perror(filename);

}

else {

                               while (fgets(buf, buff_size, fp) != NULL) {

if ((strstr (buf, str)) != NULL)

printf("%s", buf);

                           }

}

fclose(fp);

}
