c. 7
d. 7__ (each of the two underscores indicates a space)
e. None of the above

Answer 1

The output of the given code is 7.

Step-by-step explanation:

The output of the given code is c. 7.

In the code, the variable x is assigned the value 007. The printf function is used to print the value of x with the format specifier %3d. Since the format specifier %3d specifies a minimum field width of 3, the output will have at least 3 places. But since the value of x is only 1 digit, any extra places will be filled with spaces. Therefore, the output will be 7. Consequently, the output appears as '7', with two leading spaces as a result of the format specifier, illustrating the impact of formatting directives on the presentation of numerical values in programming.
