Question

the Note that you must display 4.4 Write a program that computes the sum of all the negative integers in a list As input, the program is to read the data from the data file SUMNEG. 8.80.0 of integers. dugio DAT. The data file has the following format: ore (number of integers in list) line 1 dugdeer ) wo bne line 2 int1 line 3 int2 line 4 int3 da) ds moml 1somui 0won dd mox9 mexosdts hmontd Write the output to the screen in the following manner: The sum of the negative integers is: The list of integers is: 19vre & ol visuOs rooil 2vsb to dum9rlt 9i6luplso ot msrgotq s 1ot esulev griliqmos to Sidsqso msg sinw . 03 an 2s isM.b r 21cb olit .edJAeYACbollen oliUstb smo Jucaiod bluode sisbodT D0-2) 1amiot gniwollol orl vsr bluorl lthatuses the NG 45 The rading ctruat

Please show me the source code of this problem with C language (I only learned C before), thank you~

/*
 *  C Program to sum negative integers from file
 */

#include <stdio.h>
#include <stdlib.h>

int main()
{
  int *ptrNum, N;
  int num, sum = 0, i = 0;

  FILE *fptr = fopen("SUMNEG.DAT", "r");

  fscanf(fptr, "%d", &N);
  ptrNum = (int *) malloc(N * sizeof(int));

  for (i = 0; i < N; i++)
  {
    fscanf(fptr, "%d", &num);
    ptrNum[i] = num;
    
    if (num < 0)
      sum += num;
  }

  fclose(fptr);

  printf("The sum of the negative integer is: \n%d\n", sum);
  printf("The list of integer is: \n");
  for (i = 0; i < N; i++)
  {
    printf("%d\n", ptrNum[i]);
  }
  
  return 0;
}
