Class ovo::string

void ovo::String::split(const std::string& s, std::vectorstd::string& v, const std::string& c)

Split the string.

replaceStr

void replaceStr(string& str, const string fromStr = " ", const string toStr = "", int pos = 0, const int end = 99999)

This function can search for a specific string fromStr in a string str between an interval (default the entire string), and replace fromStr with another string toStr.

params

1. string str The string need to be changed
2. string fromStr The string will be replaced by toStr (default space)
3. string toStr The string that will replace fromStr (default empty)
4. int pos The function will start searching for fromStr from position pos of str (default 0)
5. int end The function will finish searching for fromStr at position end of str (default 99999)

example 1: Using default value

#include<iostream>
#include<string>

using namespace std;

void replaceStr(string& str, const string fromStr = " ", const string toStr = "", int pos = 0, const int end = 99999)
{
    while(pos > -1 && pos < end){

        pos = str.find(fromStr, pos);
        if(pos > -1 && pos < end){
            str.replace(pos++, fromStr.length(), toStr);
        }
    }
}


int main()
{
    string str1 = "aallaaa bbbbbbb cccccccc ddddddddd";

    replaceStr(str1);

    cout << str1 << endl;
}

The string print on the screen is

aallaaabbbbbbbccccccccddddddddd

example 2: using setup value

#include<iostream>
#include<string>

using namespace std;

void replaceStr(string& str, const string fromStr = " ", const string toStr = "", int pos = 0, const int end = 99999)
{
    while(pos > -1 && pos < end){

        pos = str.find(fromStr, pos);
        if(pos > -1 && pos < end){
            str.replace(pos++, fromStr.length(), toStr);
        }
    }
}


int main()
{
    string str1 = "aallaaa bbbbbbb cccccccc ddddddddd";

    replaceStr(str1, "bbb", "22", 8, 9);

    cout << str1 << endl;
}

The string print on the screen is

aallaaa 22bbbb cccccccc ddddddddd
