concat, substring strings
Consider the following example for various operations on strings
#include <string>
#include <iostream>
using namespace std;
int main()
{
string s1("this string represents s1");
string s2("All mangoes are bananas");
string s3("snow is the purest form of water");
// Copy the first 8 chars from s1 in string s4
// string s4(<string>, <starting index>, <end index>);
string s4(s1, 0, 8);
//appending strings
string s5 = string (s1, 0, 4) + " helllo " +
string (s3, 0, 8);
// finding substring
//s3.substr(<from starting index>, <upto index>)
string s6 = s3.substr(5, 10);
string s7 = s3.substr(1, 5) + s5;
cout << s1 << endl;
cout << s2 << endl;
cout << s3 << endl;
cout << s4 << endl;
cout << s5 << endl;
cout << s6 << endl;
cout << s7 << endl;
getchar();
return 0;
}
