FAQs on C Program

What is c programming.

C is a structured, high-level, and general-purpose programming language, developed in the early 1970s by Dennis Ritchie at Bell Labs. C language is considered as the mother language of all modern programming languages, widely used for developing system software, embedded software, and application software.

How do I write a “Hello, World!” program in C?

To write a “Hello, World!” program in C, you can use the following code: #include <stdio.h> int main() { printf(“Hello, World!\n”); return 0; } This code uses the printf function to display the “Hello, World!” message on the screen.

Why should you learn C Programming?

There are many reasons why you should learn C programming: Versatility Efficiency Portability Widely used Foundation for other languages Employment opportunities and more.
