(已解决)尝试将整数转换为字符

num = 65
char = str(num)
print(char)  # 输出: '65'

int num = 65;
char ch = (char) num;
String charStr = Character.toString(ch);
System.out.println(charStr);  // 输出: 'A'

var num = 65;
var char = String.fromCharCode(num);
console.log(char);  // 输出: 'A'

int num = 65;
char ch = static_cast<char>(num);
cout << ch << endl;  // 输出: 'A'
