在字符串中使用变量可以通过字符串插值或字符串拼接的方式实现。
name = "Alice"; age = 25; print(f"My name is {name} and I'm {age} years old.")
,示例:
const name = "Alice"; const age = 25; console.log(My name is ${name} and I'm ${age} years old.
);`String name = "Alice"; int age = 25; System.out.println("My name is " + name + " and I'm " + age + " years old.");
name = "Alice"; age = 25; print("My name is " + name + " and I'm " + str(age) + " years old.")
const name = "Alice"; const age = 25; console.log("My name is " + name + " and I'm " + age + " years old.");
String name = "Alice"; int age = 25; System.out.println("My name is " + name + " and I'm " + age + " years old.");
无论是字符串插值还是字符串拼接,都可以在字符串中嵌入变量,并将其值动态地显示在最终的字符串中。这样可以方便地构建包含变量的动态字符串,适用于各种场景,如日志记录、用户界面显示、错误消息等。
