1️⃣1️⃣ 常见编程术语句子

完整示例（适合 TTS 朗读）

Declaring Variables

"Let's declare an integer variable called height."
"We assign the value five to x."
"The variable stores the user's input."

Loops

"This for loop iterates from zero to height minus one."
"The outer loop controls the rows."
"The inner loop prints the hashes."
"We increment i after each iteration."

Conditions

"If x is less than y, print x is smaller."
"While the number is greater than zero, continue the loop."
"Use a do-while loop to ensure the code runs at least once."

Functions

"This function takes two parameters: length and array."
"The function returns an integer value."
"We call the function with two arguments."
"Don't forget to declare the function prototype."

Arrays

"Create an array of three integers."
"Access the first element using index zero."
"Arrays are zero-indexed in C."
"The array is stored in contiguous memory."

1️⃣2️⃣ 易混淆的发音对比

equals (=) vs. equals (==)

• x = 5 → “x equals five” or “x gets five” (assignment)
• x == 5 → “x is equal to five” or “x double-equals five” (comparison)

Divide (/) vs. Modulo (%)

• 10 / 3 → “ten divided by three equals three”
• 10 % 3 → “ten mod three equals one”

Increment (++) vs. Add (+=)

• i++ → “increment i” or “i plus plus”
• i += 1 → “i plus equals one”

And (&&) vs. Ampersand (&)

• x && y → “x and y” (logical AND)
• &x → “address of x” (pointer, Week 4)

Or (||) vs. Pipe (|)

• x || y → “x or y” (logical OR)
• x | y → “x bitwise or y” (bitwise operation)

1️⃣3️⃣ 完整代码段朗读示例

Example: Mario Loop

代码:

for (int i = 0; i < height; i++)
{
    for (int j = 0; j < i + 1; j++)
    {
        printf("#");
    }
    printf("\n");
}

正式朗读（逐字）:

for open parenthesis int i equals zero semicolon i less than height semicolon 
i plus plus close parenthesis
open curly brace
    for open parenthesis int j equals zero semicolon j less than i plus one 
    semicolon j plus plus close parenthesis
    open curly brace
        printf open parenthesis quote hash quote close parenthesis semicolon
    close curly brace
    printf open parenthesis quote backslash n quote close parenthesis semicolon
close curly brace

自然朗读（讲解式）:

For loop: initialize i to zero, while i is less than height, increment i.
Inside the outer loop, we have another for loop: initialize j to zero, while j 
is less than i plus one, increment j.
In the inner loop, print a hash symbol.
After the inner loop, print a newline.

TTS 推荐版本（平衡）:

For loop, int i equals zero, while i less than height, increment i.
Open brace.
    Nested for loop, int j equals zero, while j less than i plus one, increment j.
    Open brace.
        Print a hash.
    Close brace.
    Print new line.
Close brace.

1️⃣4️⃣ TTS 优化建议

✅ DO（推荐）:

1. 使用完整单词: “equals” 而不是 “=”
2. 添加停顿: 用逗号和句号控制节奏
3. 自然语言: “while i is less than ten” 而不是 “while i < 10”
4. 明确说明: “open parenthesis” 而不只是 “(“

❌ DON’T（避免）:

1. 符号堆砌: 不要说 “( i < 10 )”
2. 过度简化: 不要跳过重要的符号
3. 混合中英文: TTS 可能读错
4. 过长句子: 一次说太多会难以理解

✨ 总结

最重要的发音规则:

1. 符号要说出来: < 是 “less than”，不能跳过
2. 区分赋值和比较: = vs ==
3. 逻辑运算符要清晰: && 是 “and”，|| 是 “or”
4. 数字要完整: 不要说 “nine two”，要说 “ninety-two”

练习优先级:

1. ⭐⭐⭐ 运算符（最常用）
2. ⭐⭐⭐ 数据类型和关键字
3. ⭐⭐ 完整代码行
4. ⭐ 复杂嵌套结构

准备好后，就可以开始使用 Role Play Script 了！🎓
