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.
