Leio arquivo mas não consigo comparar com IF


Question

Pessoal bom dia. Estou reaprendendo a programar, depois de um acidente que me fez perder muita coisa, inclusive memoria.

Fiz um programa que pega um valor que ta num arquivo e armazena numa variavel, mas não consigo comparar pra ver se é igual a alguma palavra que tenho. podem me ajudar?

#include <iostream>
#include <stdlib.h>
#include <stdio.h>
#include <conio.h>
using namespace std;

int main()
{
  FILE *arq;
  char Linha[20]={ };
  char ch;
  char *result;
  int i;
  system("powershell \"Get-CimInstance -ClassName Win32_ComputerSystem | foreach { $_.Manufacturer }\" > arqsnipe.txt");
  arq = fopen("arqsnipe.txt", "rt");
  result = fgets(Linha, 20, arq);
  for (i=0;i<=19;i++){
    printf("%c - %i\n",Linha, i);
  }
  fclose(arq);

  if (Linha == "Hewlett-Packard"){
    printf("\nOpcao 1\n");
  }else{
    printf("\nOpcao 2\n");
  }
}
