Combining strings and numbers using ssstream

0. Header file and namespace

#include <iostream>
#include <string>
#include <sstream>
#include <vector>

using namespace std;

1. Realization

Use opencv when , Easily read numbered pictures

int main(){
    string path = "C:/imgs/";
    stringstream stm;
    string temppath;
    vector<string>imgspath;
    for (int i = 1; i < 10; i++)
    {
        stm << i;
        stm >> temppath;
        path = path + temppath + ".jpg";
        cout << path << endl;
        imgspath.push_back(path);
        path = "C:/imgs/";
        // stm Data can be written only after the data in is cleared 
        stm.clear();
    }
    return 0;
}

2. Read more data

int main(){
    //  When you want to be in stringstream When storing more content in , Can be entered at one time 
    string s1 = "hello ";
    string s2 = " world ";
    int value1 = 1;
    int value2 = 2;
    stringstream ss;
    ss << s1 << value1 << s2 << value2;
    cout << ss.str() << endl;
    return 0;
}

3. Complete code

#include <iostream>
#include <string>
#include <sstream>
#include <vector>

using namespace std;

int main(){
    string path = "C:/imgs/";
    stringstream stm;
    string temppath;
    vector<string>imgspath;
    for (int i = 1; i < 10; i++)
    {
        stm << i;
        stm >> temppath;
        path = path + temppath + ".jpg";
        cout << path << endl;
        imgspath.push_back(path);
        path = "C:/imgs/";
        // stm Data can be written only after the data in is cleared 
        stm.clear();
    }
    //  When you want to be in stringstream When storing more content in , Can be entered at one time 
    string s1 = "hello ";
    string s2 = " world ";
    int value1 = 1;
    int value2 = 2;
    stringstream ss;
    ss << s1 << value1 << s2 << value2;
    cout << ss.str() << endl;
    return 0;
}
