1 * 10^15 to

1 * 10^16. So, when I write a number without 0 (for example, 3445674589632452), the code works as intended, and when I enter a number with 0 (for example, 3445674589630052), it gives me a negative number (-1048) instead 52. Please tell me what I should do.

C:

```
#include <stdio.h>
#include <cs50.h>
#include <math.h>
int main (void)
{
long number ;
number = get_long("Number: ");
if (number < 0 )
{
do
{
number = get_long("Number: ");
}
while ( number < 0 );
}
if (number > 0 && number < 10000000000000)
{
printf("INVALID\n");
return number;
}
if (number >= 100000000000000 && number < 1000000000000000)
{
printf("INVALID\n");
return number;
}
if ( number >= 100000000000000000)
{
printf("INVALID\n");
return number;
}
if (number == 0 )
{
printf("INVALID\n");
return number;
}
if (number >= 3400000000000000 && number < 3500000000000000)
{
do
{
number -= 1000000000000000;
}
while(number > 1000000000000000);
do
{
number -= 100000000000000;
}
while(number > 100000000000000);
do
{
number -= 10000000000000;
}
while(number > 10000000000000);
do
{
number -= 1000000000000;
}
while(number > 1000000000000);
do
{
number -= 100000000000;
}
while(number > 100000000000);
do
{
number -= 10000000000;
}
while(number > 10000000000);
do
{
number -= 1000000000;
}
while(number > 1000000000);
do
{
number -= 100000000;
}
while(number > 100000000);
do
{
number -= 10000000;
}
while(number > 10000000);
do
{
number -= 1000000;
}
while(number > 1000000);
do
{
number -= 100000;
}
while(number > 100000);
do
{
number -= 10000;
}
while(number > 10000);
do
{
number -= 1000;
}
while(number > 1000);
do
{
number -= 100;
}
while(number >= 100);
printf("%li\n" ,number );
printf("AMEX\n");
}
```
