Learn C language with a programmer’s mindset: basic syntax: variables, data types, constants, operators, control flow. Practical case: Calculate the average of two numbers. Enter two integers and calculate their average.

Think like a programmer: learn the basics of C language

Introduction
Learn programming It's not difficult, especially if you think like a programmer. This article will start from the basics and use C language to guide you step by step to understand the introductory knowledge of programming.

Basic syntax of C language

• Variable: Container used to store data, with types (int, float, char) and name.
• Data type: defines the format in which variables store data.
• Constant: An unchangeable value.
• Operator: performs arithmetic, logical, or assignment operations.
• Control flow: is used to control the execution order of code in the program.

Sample code (C)

#include 

int main() {
    int num1, num2, sum;

    num1 = 10;
    num2 = 20;
    sum = num1   num2;

    printf("求和结果：%d\n", sum);
    return 0;
}

Practical case
Calculate the average of two numbers

Requirements:

• accepts two integers as input.
• Calculates and displays the average of these two numbers.

Solution (C)

#include 

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

    printf("输入两个整数：");
    scanf("%d %d", &num1, &num2);

    // 计算平均值
    average = (num1   num2) / 2;

    printf("平均值为：%d\n", average);
    return 0;
}

Conclusion
By understanding the basic syntax of C language and practicing practical cases, you have embarked on the road to programming. Keep practicing, go deeper step by step, and you will unlock the unlimited potential of the programming world.
