学习C++常遇见的问题之语法错误

i.错误示例：int x = 5 int y = 10

ii.纠正方法：确保每一行的语句末尾都有分号，例如int x = 5; int y = 10;

i.错误示例：if (x > 5) { std::cout << "x is greater than 5";

ii.纠正方法：使用括号配对工具或养成良好的缩进习惯，确保每一对括号都正确闭合，例如if (x > 5) { std::cout << "x is greater than 5"; }

i.错误示例：intmain() { intx = 5; std::cout << "x is " << x; }

ii.纠正方法：仔细检查关键字和标识符的拼写，例如int main() { int x = 5; std::cout << "x is " << x; }

i.错误示例：int main() { cout << "Hello, World!"; }

ii.纠正方法：确保包含了所有使用的库或头文件，例如#include <iostream> int main() { std::cout << "Hello, World!"; }
