How to implement a flag control in my loop?

Code:

---

int main()
  {
  int total_value=0;
  char mychar;
  int mynum;
 
  do
  {
  printf("Line: ");
  scanf("%c",&mychar);
  mynum=mychar;
  total_value=total_value+mynum;
  } while(mychar!='.');
 
  printf("Checksum %c",total_value);
 
 
  return 0;

My code works fine. It does the calculations and prints out the results. However with a bit of extras.

So basically how do i implement a flag-control in this loop. Such that the program does calculations until it reachs a '.' (period)

Code:

---

while(flag=1)
{

}
while(mynum!='.')
{
}

Are you sure? This

Code:

---

printf("Checksum %c",total_value);

prints "total_value" as a character. I think you want to use %d to print the sum.
