Functions in C are self-contained blocks of code designed to perform specific tasks. They promote modularity and code reusability by allowing a program to be broken down into smaller, manageable units.

Functions in C are blocks of code that perform specific tasks. They can be defined with a return type, name, and parameters. Example: int add(int a, int b) { return a + b; } Functions help modularize code and improve reusability.

What is meant by "bit masking"?
For example if you want to know if third bit is 1 or not for an int x then you can mask all other bits and just check the third one: (n & 0x04) != 0 means 3rd bit is not zero, 0x04 is the bit mask

Why does execution of a program in C/C++/Java start from only main?
Main function is calling the other functions of he program and compiler gets this direction while Compiling the code. If it does not find main function then it will also not find the other functions in the code. So, main is required in C program.
