Strings in C++ Hacker Rank Solution
Problem
C++ provides a nice alternative data type to manipulate strings, and the data type is conveniently called string. Some of its widely used features are the following:
Declaration:
string a = "abc";
Size:
int len = a.size();
Concatenate two strings:
string a = "abc"; string b = "def"; string c = a + b; // c = "abcdef".
Accessing i th element:
string s = "abc"; char c0 = s[0]; // c0 = 'a' char c1 = s[1]; // c1 = 'b' char c2 = s[2]; // c2 = 'c' s[0] = 'z'; // s = "zbc"
P.S.: We will use cin/cout to read/write a string.
Input Format
You are given two strings, a and b, separated by a new line. Each string will consist of lower case Latin characters (‘a’-‘z’).
Output Format
In the first line print two space-separated integers, representing the length of a and b, respectively.In the second line print the string produced by concatenating a and b(a+b).In the third line print two strings separated by a space, a’ and b’.a’ and b’ are the same as a and b, respectively, except that their first characters are swapped.
Sample Input :
abcd ef
Sample Output :
4 2 abcdef ebcd af
Explanation :
- a = “abcd”
- b = “ef”
- |a| = 4
- |b| = 2
- a+b = “abcdef”
- a’ = “ebcd”
- b’ = “af”
Strings in C++ Hacker Rank Solution
#include <iostream>
#include <string>
using namespace std;
int main()
{
string str1,str2,str3;
char b,a;
int strlen1,strlen2;
//string one
cin>>str1;
//string two
cin>>str2;
//first string size
strlen1 = str1.size();
//second string size
strlen2 = str2.size();
cout<<strlen1;
cout<<" "<<strlen2;
// concatinate two string
str3 = str1+str2;
cout<<"\n"<<str3;
// a' b'
a = str2[0];
b = str1[0];
str1[0] = a;
str2[0] = b;
cout<<"\n";
cout<<str1;
cout<<" "<<str2;
return 0;
