creating substring in c++
// string::substr
#include <iostream>
#include <string>
int main ()
{
std::string str="We think in generalities, but we live in details.";
// (quoting Alfred N. Whitehead)
std::string str2 = str.substr (3,5); // "think"
std::size_t pos = str.find("live"); // position of "live" in str
std::string str3 = str.substr (pos); // get from "live" to the end
std::cout << str2 << ' ' << str3 << '\n';
return 0;
}
// CPP program to illustrate substr()
#include <string.h>
#include <iostream>
using namespace std;
int main()
{
// Take any string
string s1 = "Geeks";
// Copy three characters of s1 (starting
// from position 1)
string r = s1.substr(1, 3);
// prints the result
cout << "String is: " << r;
return 0;
}
