All valid C programs must contain the main() function. The code execution begins from the start of the main() function. The printf() is a library function to send formatted output to the screen. The function prints the string inside quotations. To use printf() in our program, we need to include stdio.h header file using the #include

If instead a programmer defines a function by himself and place the .h file in the current working directory, he would use (note the double quotes) #include "stdio.h"
🙋 Introduction. The header file in C is one of the most commonly used and essential libraries. It provides functionalities for input and output operations, making it a crucial part of any C programmer's toolkit.

Both the stack and heap memory segments during execution. Here's a breakdown: Stack: Function arguments (argc, argv): These arguments are passed to the main function and stored on the stack. Local variables: Variables declared within the main function, including input, ch, lCnt, and bCnt, reside on the stack. Return address: When the main function calls a function like fopen or printf, the ...
