What is the Correct Format Specifier for an Integer in C? | C Programming Quiz 5

Welcome to our C programming quiz series! Today, we’re focusing on format specifiers, a crucial part of input and output operations in C. If you’re learning C or brushing up on your skills, understanding format specifiers is essential. They tell the printf and scanf functions how to interpret the data types you’re working with.

In this Short, we present four options for the correct format specifier for an integer:

a) %c
b) %d
c) %s
d) %f
But which one is correct?

Let’s briefly explore each option:

Option a) %c: This format specifier is used for characters, not integers. It tells the program to expect a single character and handle it accordingly.
Option b) %d: This is the correct answer! In C, %d is the format specifier used for integers. It stands for "decimal" and is used to represent signed decimal integers in both printf and scanf.
Option c) %s: This specifier is used for strings, which are arrays of characters. It’s not suitable for integers.
Option d) %f: This format specifier is used for floating-point numbers. It’s perfect for handling decimal values but not for integers.
Understanding and correctly using format specifiers is vital in C programming because it ensures that your input and output functions behave as expected. This knowledge is particularly important when dealing with user inputs, file handling, or any operation that requires precise data type control.
