I'm currently a student taking C++. I found some old C code that I'm trying to convert tom C++. Here is the code with the corresponding error messages. I hope someone can help.
Thanks,

#include<string.h>
void main()
static int verify_checksum(char *credit_card)
{
char *cp;
int dbl;
int check_sum;
check_sum = 0;
dbl = 0;
cp = credit_card + strlen(credit_card) -1;
while (cp >= credit_card)
{
int c;
c = *cp-- -'0';
if (dbl)
{
c *= 2;
if (c >= 10)
c -= 9;
}
check_sum += c;
dbl = !dbl;
}
return ((check_sum % 10) == 0);
}
//eof
