CPP Program copy a string in three different ways

 In this program, discussion about how to copy the string in the three different methods in the cpp programming language.

Ist method: string object

Code:

#include <iostream>

using namespace std;

int main()

{

    string str1, str2;

    cout << "Enter string s1: ";

    getline (cin, str1);

    str2 = str1;

    cout << "string1 = "<< str1 << endl;

    cout << "string2 = "<< str2;

    return 0;

}

Second method: Copy c string

Code:

#include <iostream>

#include<cstring>

using namespace std;

int main()

{

    char str1[100], str2[100];

    cout << "Enter string s1: ";

    cin.getline(str1,100);

    strcpy(str2,str1);

    cout << "string1 = "<< str1 << endl;

    cout << "string2 = "<< str2;

    return 0;

}

3RD METHOD: By using loop

Code:

#include <iostream>

#include<cstring>

using namespace std;

int main()

{

    char str1[100], str2[100];

    cout << "Enter string s1: ";

    cin.getline(str1,100);

    for(int i=0;str1[i]!='\0';i++)

    {

     str2[i]=str1[i];

}

    cout << "string1 = "<< str1 << endl;

    cout << "string2 = "<< str2;

    return 0;

}
