How would I go about converting a two-digit number (type char*) to an int?
I want to convert the value from token to integer value atoi and strtol produce erroneous results
output is
815102162524#622101830754
token = 815102162524
token = 622101830754
815102162524, 622101830754
2147483647, 2147483647

int main(void) {
char buffer[] = "815102162524#622101830754\n";
long long int num1, num2;
char *p;
printf("Long long %u bits\n",sizeof(num1)*8);
num1 = strtoll(buffer, &p, 10);
printf("token = %c\n", *p);
num2 = strtoll(p+1,NULL,10);
printf("%lld, %lld\n",num1,num2);
}
Output
Long long 64 bits
token = #
815102162524, 622101830754
