Question

Document2 Tell me Layout References Mailings Review View 1. Write a program named Lab17B that will read 2 strings and compare them. a. Create a bool function named compareLetters that will accept 2 string variables as parameters and will return true if the strings have the same first letters and the same last letters. It will return a false otherwise. b. Create a bool function named inside that will accept the 2 string variables in the order they were entered) and will return a true if the first string has the second string inside it. (Ex - coldest & old would return a true because old is contained in coldest.) It will return a false otherwise. c. In your main function: i. ask the user to enter 2 strings on separate lines, ii. call the two functions with them iii. print the results with labels sh (United States) Focus

using namespace std;
#include <iostream>
bool compareLetters(string s1, string s2);
bool inside(string s1, string s2);
int main()
{
string letter1;
cout << "Enter first letter ";
   cin >> letter1;
string letter2;
cout<<"Enter second letter ";
cin>> letter2;

   if (compareLetters(letter1,letter2) == true)
cout<<"compareLetters() function result--True ";
else
cout<<"compareLetters() function result--False ";
   if( inside(letter1,letter2)==true)
   cout<< "inside() function result--True ";
   else
   cout<<"inside() function result--False ";
}

bool compareLetters(string s1, string s2)
{

   int n1=s1.length();
   int n2= s2.length();
   if(s1[0]==s2[0] && s1[n1-1]==s2[n2-1])
return true;
else
return false;
}

bool inside(std::string s1,std::string s2){
if(s2.size() > s1.size())
return false;

for (int i = 0; i < s1.size(); i++){
int j = 0;
// If the first characters match
if(s1[i] == s2[j]){
int k = i;
while (s1[i] == s2[j] && j < s2.size()){
j++;
i++;
}
if (j == s2.size())
return true;
else // Re-initialize i to its original value
i = k;
}
}
return false;
}
