Program Execution and printf()

Welcome to the notes on Program Execution
and printf() Function in C! This set of notes will focus
specifically on:

 Program Execution
 printf() Function
Program Execution
Program execution in C starts with the main() function.
It is the entry point of a C program and is where the
program starts executing.

When a C program is executed, here is the order of
operations:

1. The program is loaded into memory by the
operating system.
2. The program's executable code is loaded into the
computer's memory.
3. The program's data is initialized.
4. The main() function is called and program
execution begins.
5. Control is transferred to other functions as needed.
printf() Function
The printf() function is a powerful tool for outputting
text and formatted data in C programs. Here are some
key points about the printf() function:

 It is defined in the standard I/O library in C.
 It takes a string as its first argument, called a
format string, that describes the desired output.
 The format string can contain placeholders,
represented by % symbols, for variables to be
inserted into the output.
