C language is a general programming language. The steps to get started are: prepare a text editor and compiler; master basic syntax: variables, operators, control flow and functions; practical exercises: write programs to calculate averages and understand input /Output, data types and control flow.
Unleash your inner system architect: Introduction to C programming
C language is a powerful general-purpose programming language. Known as the "mother of all programming languages". It is known for its efficiency, portability, and low-level control. C is an excellent choice for anyone who wants to learn the fundamentals of programming.
Introduction to C
A compiled language like C consists of source files that contain human-readable code. The source files are translated by the compiler into machine-executable binary code.
To start writing C programs, you need a text editor (such as Notepad or Sublime Text) and a compiler (such as MinGW or Clang).
Basic syntax
The basic syntax of C language includes:
Practical case: calculation Average
Here is a simple and common C program that calculates the average of a set of numbers:
#include <stdio.h> int main() { int n, sum = 0, num; printf("Enter the number of elements: "); scanf("%d", &n); for (int i = 0; i < n; i++) { printf("Enter number %d: ", i + 1); scanf("%d", &num); sum += num; } float avg = (float)sum / n; printf("Average: %.2f\n", avg); return 0; }
Understanding the code
#include ade979de5fc0e1ca0540f360a64c230b
: Contains the standard input/output library. int n, sum = 0, num;
: declare variables. printf
and scanf
: for input and output. for
Loops to read the numbers entered by the user and add them. float avg = (float)sum / n;
: Calculate the average and convert it to a floating point number. Through this practical case, you can understand the basic syntax, data types, input/output and control flow of C language.
