What is execution of program in C?

Execution Flow The preprocessor generates an expanded source code. 2) Expanded source code is sent to compiler which compiles the code and converts it into assembly code. 3) The assembly code is sent to assembler which assembles the code and converts it into object code.

What is C programming in simple words?

The C programming language is a computer programming language that was developed to do system programming for the operating system UNIX and is an imperative programming language. The language itself has very few keywords, and most things are done using libraries, which are collections of code for them to be reused.

How was C language created?

The origin of C is closely tied to the development of the Unix operating system, originally implemented in assembly language on a PDP-7 by Dennis Ritchie and Ken Thompson, incorporating several ideas from colleagues. Eventually, they decided to port the operating system to a PDP-11.

Where does the program execution start and end in C++?

Program execution Starts and Ends at “main ()” function. whenever the function is called then its activation record is pushed into stack and keep on updating. when function completed its execution it will be pop out of the stack.

What is the starting point of a program in C?

What is the starting point of C program? Take input from the user: scanf function is used to take the input from the user. When you run this program, it waits for a user input (age) and once user enters the age, it does the processing of rest of the statements based on the age input by user.
