[C] executable programs closing suddenly

Hi,
I'm new to programming and I'm learning the C language.

I use the most current DevCpp. When I click compile + run the codes, they work. However, when I open the .exe files the software only works until the data is entered. When I hit 'enter' to continue processing, they suddenly close.

I leave here one of the scripts so that, if possible, someone can help me.

Thank you!

What I have tried:

#include<stdio.h>
main()
{
int num;
printf("Digite um numero inteiro: ");
scanf("%d",&num);
if (num % 2 == 0) {
printf("Este numero e par!");
}
else {
printf("Este numero e impar!");
}
}

At the end of the main function the program terminates and control is back to OS.
A workaround to keep the program alive is asking the user for another input, try

C

#include<stdio.h>
int main()
{
  int num;
  printf("Digite um numero inteiro: ");
  scanf("%d",&num);
  if (num % 2 == 0)
  {
    printf("Este numero e par!\n");
  }
  else
  {
    printf("Este numero e impar!\n");
  }

  printf("program is paused. Please enter a key to exit\n");
  scanf("%d", &num);

  return 0;
}

Another approach using getch()

C

#include<stdio.h>
#include <conio.h> // for getch()

int main()
{
  int num;
  printf("Digite um numero inteiro: ");
  scanf("%d",&num);
  if (num % 2 == 0)
  {
    printf("Este numero e par!\n");
  }
  else
  {
    printf("Este numero e impar!\n");
  }

  printf("program is paused. Please enter a key to exit\n");
  getch();

  return 0;
}
