C Question

I want my code to prompt the user to input a phone number of form 1(xxx)-xxx-xxxx and then sum the digits of the number. However I do not know what is wrong with my code. See below

`printf("Enter a phone number in 1(xxx)-xxx-xxxx format: \n");`

scanf(" %*c%*c%d %d %d %*c%*c%d %d %d %*c%d %d %d %d", &i, &j, &k, &l, &m, &n, &o, &p, &q, &r);

sum = (i + j + k + l + m + n + o + p + q + r);

realsum = sum + 1;

printf("The sum of the digits = %d \n\n", realsum)

;

Can anyone help? It seems to be assigning the first part of the number (xxx) entirely to i, and j is zero. How do I get it to assign each digit to each variable one by one?

Answer

You did account for the non-integer characters that the user enters, but integers are read as a whole, so `123`

is not read as`1`

then `2`

then `3`

but rather as `123`

.

```
scanf(" %*c%*c%d %*c%*c%d %*c%d ", &i, &j, &k);
```
