C is an entry-level programming language that provides a solid foundation. Variables are used to store data, and data types define the data types that variables can store (such as integers, characters). Input and output are performed via standard functions. Conditional statements allow different blocks of code to be executed based on conditions. Loops execute blocks of code repeatedly. An array is a collection of data of the same type. A practical example shows a procedure for calculating the average of two numbers.

Unlock Your Coding Potential: C Programming for Absolute Beginners

Step into the wonderful world of programming and start with C language from the basics ! As an entry-level language, C is easy to understand and provides you with a solid foundation in programming.

Variables and Data Types

Variables are used to store data, while data types define the type of data a variable can store. For example:

int age; // 整型变量,存储年龄
char name[25]; // 字符数组,存储最多 24 个字符的名字
float weight; // 浮点型变量,存储重量

Input and output

Through the standard input and output functions (printf and scanf), user input can be read and output information can be printed . For example:

printf("请输入你的年龄:");
scanf("%d", &age);
Copy after login

Conditional Statement

Conditional statement allows you to execute different blocks of code based on conditions. For example:

if (age >= 18) {
  printf("你是成年人了。");
} else {
  printf("你未成年。");
}

Loop

Loop allows you to execute a block of code repeatedly. For example:

for (int i = 0; i < 5; i++) {
  printf("你好,世界!\n");
}
Copy after login

Array

An array is a group of data elements that store the same type. For example:

int numbers[] = {1, 2, 3, 4, 5};
Copy after login

Actual Case

Let us write a simple program to calculate the average of two numbers:

#include <stdio.h>

int main() {
  int num1, num2;
  float average;

  printf("请输入第一个数字:");
  scanf("%d", &num1);

  printf("请输入第二个数字:");
  scanf("%d", &num2);

  average = (float)(num1 + num2) / 2;

  printf("平均值为:%.2f\n", average);

  return 0;
}
Copy after login
