C++ String Manipulation

C++ append() function

The append() function is used to add a string to the end of another string. The append() function has two forms. The first form appends all characters in a string to another string. The second form appends part of string to another string. This proportion of string is taken out by starting from the start argument and the num_chars arguments specifies the number of characters to be taken out.

append(string);

append(string, start, num_chars);



Example:

#include <cstdlib>
#include <iostream>
#include <conio.h>


using namespace std;

void strmanip(){

  string str="C++ programming";
  str.append(" in easy steps");//append entire string " in easy steps" to another string str
  cout<<str<<endl;
  str.append(" in easy steps",3,5);//append part of string " in easy steps" to another string str
  cout<<str<<endl;

}

int main(){

  strmanip();
  getch();
  return 0;

}
