String::Find
SizeType Find(const char* str, SizeType pos = 0) const;
在字符串中查找子串 str,从位置 pos 开始搜索。
参数:
str- 要查找的以 null 结尾的 C 字符串pos- 开始搜索的位置,默认为 0
返回: 子串首次出现的起始位置;如果未找到,返回 String::npos
复杂度: O(n * m),其中 n 为原字符串长度,m 为要查找的字符串长度
示例:
#include "XCEngine/Containers/String.h"
#include <iostream>
int main() {
XCEngine::Containers::String s("Hello World, Hello Universe");
XCEngine::Containers::String::SizeType pos1 = s.Find("World");
std::cout << "Found at: " << pos1 << std::endl; // 输出: Found at: 6
XCEngine::Containers::String::SizeType pos2 = s.Find("Hello", 0);
std::cout << "First 'Hello' at: " << pos2 << std::endl; // 输出: First 'Hello' at: 0
XCEngine::Containers::String::SizeType pos3 = s.Find("Hello", 7);
std::cout << "Second 'Hello' at: " << pos3 << std::endl; // 输出: Second 'Hello' at: 13
XCEngine::Containers::String::SizeType pos4 = s.Find("NotFound");
if (pos4 == XCEngine::Containers::String::npos) {
std::cout << "Not found" << std::endl; // 输出: Not found
}
return 0;
}
