Printing a Number in C

To print a number in C, you can use the printf function from the standard input-output library. Here's a step-by-step explanation of how to do this:

  1. Include the Required Header File:
  2. Before using the printf function, you need to include the standard input-output header file in your program using the #include directive.
  3. This is done to make the printf function available for use in your program.

Example:c #include <stdio.h>

  1. Use the printf Function:
  2. Once you've included the required header file, you can use the printf function to print a number to the console.
  3. The printf function takes a format string as its first argument, which specifies how the output should be formatted, and additional arguments that represent the values to be printed.

Example:c int number = 10; printf("The number is: %d", number);

In this example, %d is a format specifier that indicates the location where the value of number should be inserted in the output.

  1. Compile and Run the Program:
  2. After writing the code, you need to compile it using a C compiler, such as GCC, and then run the compiled executable to see the output.

Example:bash gcc -o output_file input_file.c ./output_file

Replace output_file with the desired name for the compiled executable and input_file.c with the name of your C source code file.
