string - Parsing a text file in C -

i making program displays element of choice periodic table using file. try compare string line of file, doesn't work. how can fix comparison?

#include <stdio.h> #include <stdlib.h> #include <string.h>  int main() {     char * line = null;     char name_element[1000];     size_t len=0;     ssize_t read;      file*table;     table=fopen("data.txt","r");      printf("please enter element looking for:\n");     scanf("%s",name_element);      while ((read = getline(&line, &len, table))!=-1){         i=strcmp(name_element,line);         if  (strcmp(line,name_element)==0) {             while ((read = getline(&line, &len, table))!=-1) {                 if(strcmp(line,"////")!=0) {                     printf("%s", line);                 } else {                     break;                 }             }         }     }         fclose(table);     return 0; } 

in future, may want include input file, in case part of problem.

assuming won't cause problems, strncmp() way go. format strncmp(str1, str2, n) n number of characters want compare.
