Think Like a Programmer: Learning the Fundamentals with C

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: Define the format in which the variable stores data.
• Constant: An unchangeable value.
• Operators: Perform arithmetic, logical or assignment operations.
• Control flow: is used to control the execution order of code in the program.

Example code (C)

#include <stdio.h>

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.
• Calculate and display the average of these two numbers.

Solution (C)

#include <stdio.h>

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.
