我做了一个c++字符串,它将使用find和substring命令分成子字符串,并且一直存在子字符串多于指令的问题。它们应该是没有数字的句子。 #include <iostream> #include <algorithm> #include <string.h> using namespace std; int main() { string questions = "1. pog 2. pog2 3. pog3 4. pog4"; int q1in...
include <conio.h> int main(){ char src[1001] = {0};char sub[20] = {0};void findSubString(char src[],char sub[]);printf("Input the string: ");gets(src);//输入字符串 gets(sub);findSubString(src, sub);return 0;} void findSubString(char src[],char sub[]){ int ...
substr(pos, 5); // 从找到的位置开始,截取长度为5的子字符串 std::cout << "Substring: " << sub_str << std::endl; // 输出 "World" } else { std::cout << "'World' not found." << std::endl; } return 0; } 通过这两个函数的结合使用,你...
返回substring首次在string中出现的位置,若未找到,则返回0。 startpos指定从 string的何处开始搜索substring,正值从左至右,负值反向。 Modifier=I,搜索时忽略大小写,默认区分大小写。 /FIND函数应用举例/ data test3; string1='1234567890'; 登录后复制pos1=find(string1, '3');put'pos1=' pos1;string2='c:...
namespace CSharpExamples { class Program { static void Main(string[] args) { string str = "HelloWorld"; int startIndex = 4; string substring = str.Substring(startIndex); Console.WriteLine("Substring is : "+substring); } } } Output ...
* @brief Find position of a C substring. * @param __s C string to locate. * @param __pos Index of character to search from. * @param __n Number of characters from @a s to search for. * @return Index of start of first occurrence. ...
rfindmethod has a similar structure asfind. We can utilizerfindto find the last substring or specify a certain range to match it with the given substring. #include<iostream>#include<string>using std::cin;using std::cout;using std::endl using std::string;using std::stoi;intmain(){string ...
1.api说明 (1)substring str.substring(indexStart[, indexEnd]) substring 提取从 indexStart 到 indexEnd(不包括)之间的字符.特别地: 如果 indexStart 等于 indexEnd,substring 返回一个空字符串. 如果省略 indexEnd,substring 提取字符一直到字符串末尾. 如果任一参数小于 0 或为 NaN,则被当作 0. 如果任一...
i.e. the found substring must not begin in a position preceding pos.1) Finds the first substring equal to str.2) Finds the first substring equal to the first count characters of the character string pointed to by s. s can include null characters.3) Finds the first substring ...
You are given a number of case-sensitive strings of alphabetic characters, find the largest string X, such that either X, or its inverse(相反,倒转) can be found as a substring of any of the given strings. Input The first line of the input file contains a single integer t (1 <= t...
