我是一个c语言初学者，请问有哪些简单有趣的程序供我参考联系

作为一名C语言初学者，你可以从以下几个简单而有趣的程序开始练习：

1. **Hello, World!**：这是学习任何编程语言的第一步，编写一个简单的程序输出"Hello, World!"。

#include <stdio.h>

int main() {
    printf("Hello, World!\n");
    return 0;
}

2. **计算器**：创建一个基础的命令行计算器，可以进行加减乘除运算。

#include <stdio.h>

int main() {
    char operator;
    double num1, num2;

    printf("Enter operator (+, -, *, /): ");
    scanf("%c", &operator);

    printf("Enter two numbers: ");
    scanf("%lf %lf", &num1, &num2);

    switch (operator) {
        case '+':
            printf("%.1f + %.1f = %.1f\n", num1, num2, num1 + num2);
            break;
        case '-':
            printf("%.1f - %.1f = %.1f\n", num1, num2, num1 - num2);
            break;
        case '*':
            printf("%.1f * %.1f = %.1f\n", num1, num2, num1 * num2);
            break;
        case '/':
            if (num2 != 0)
                printf("%.1f / %.1f = %.1f\n", num1, num2, num1 / num2);
            else
                printf("Error: Division by zero is not allowed.\n");
            break;
        default:
            printf("Invalid operator. Please use +, -, *, or /\n");
            break;
    }

    return 0;
}

3. **猜数字游戏**：让用户猜测一个随机生成的整数，直到猜对为止。

#include <stdio.h>
#include <stdlib.h> // for rand and srand

int main() {
    int number_to_guess, guess, tries = 0;
    srand(time(0)); // initialize random seed

    printf("Guess a number between 1 and 100: \n");
    do {
        scanf("%d", &guess);
        ++tries;
        if (guess < number_to_guess) {
            printf("Too low! Try again.\n");
        } else if (guess > number_to_guess) {
            printf("Too high! Try again.\n");
        }
    } while (guess != number_to_guess);

    printf("Congratulations! You guessed the number in %d tries.\n", tries);
    return 0;
}

这些项目不仅有助于你熟悉基本语法和控制结构，还能让你理解变量、输入输出、条件语句和循环等概念。完成这些后，你可以尝试更复杂的程序，比如字符串处理或文件操作。记住，实践是提高编程技能的关键，祝你学习愉快！
