Answer 1

The format specifier %10d should be used to display the value of the number variable in a field that is 10 spaces wide, with comma separators.

Step-by-step explanation:

The correct format specifier to display the value of the number variable in a field that is 10 spaces wide, with comma separators, is %10d.

The %d format specifier is used to print an integer value. The %10 specifies that the field width should be 10 characters wide, right-aligned. The comma separators can't be directly added using a format specifier, so you would need to add them separately.

Here's an example:

int number = 123456; printf("%10d", number); // Output: 123456
