Which format specifier is used for `int` values?
A. %f
B. %x
C. %i
D. %d
Answer (1)
%f is for floating-point numbers.
%x is for hexadecimal integers.
%i and %d are for decimal integers, but %d is more common for printing.
The correct format specifier for 'int' values is % d .
Explanation
Understanding the Question The question asks which format specifier is used for 'int' values in a programming context. The options are: %f, %x, %i, and %d.
Analyzing the Options Let's analyze each option:
%f: This format specifier is used for floating-point numbers (e.g., 3.14, 2.718). So, it's not for integers.
%x: This format specifier is used for hexadecimal integers (base-16 numbers). While it represents integers, it's not the general format specifier for 'int' values.
%i: This format specifier is used for decimal integers.
%d: This format specifier is also used for decimal integers.
Choosing the Correct Specifier Both %i and %d can be used for 'int' values. However, %d is generally the more common and widely used format specifier for printing integers in C-like languages. While %i can also be used for input to interpret integers in different bases (decimal, octal, hexadecimal), %d is specifically for decimal integers.
Final Answer Therefore, the correct answer is d. %d .
Examples
In programming, when you want to display an integer value on the screen or write it to a file, you use a format specifier to tell the program how to interpret the data. For example, if you have an integer variable age = 30 and you want to print it, you would use printf("The age is %d", age); . The %d tells the program to treat the age variable as a decimal integer and display its value. This is fundamental in creating readable and informative output in software applications.
