s: madam, abba, 22, 67876, 444244, trymeuemyrt Modify the function isPalindrome of Example 6-6 so that when determining whether a string is a palindrome, cases are ignored, that is, uppercase and lowercase letters are considered the same. The isPalindrome function from Example 6-6 has been included below for your convenience.bool isPalindrome(string str){int length = str.length();for (int i = 0; i < length / 2; i++){if (str[i] != str[length - 1 - i] )return false;}return true;}

Answer:

#include <bits/stdc++.h>

using namespace std;

bool isPalindrome(string str)

{

   char a,b;

int length = str.length();

for (int i = 0; i < length / 2; i++)

{

   a=tolower(str[i]);//Converting both first characters to lowercase..

   b=tolower(str[length-1-i]);

   if (b != a )

return false;

}

return true;

   

}

int main() {

   string t1;

   cin>>t1;

   if(isPalindrome(t1))

   cout<<"The string is Palindrome"<<endl;

   else

   cout<<"The string is not Palindrome"<<endl;

return 0;

}

Output:-

Enter the string

madam

The string is Palindrome

Enter the string

abba

The string is Palindrome

Enter the string

22

The string is Palindrome

Enter the string

67876

The string is Palindrome

Enter the string

444244

The string is not Palindrome

Explanation:

To ignore the cases of uppercase and lower case i have converted every character to lowercase then checking each character.You can convert to uppercase also that will also work.

Misha Larkins [42]

Answer:

The program to this question can be given as:

Program:

def swap_values(user_val1, user_val2):  #define function

   return (user_val2, user_val1) #return values

if __name__ == '__main__': #define constructor.

   n1 = int(input('Enter first number :')) #input value form user

   n2 = int(input('Enter second number :')) #input value form user

   (n1,n2) = swap_values(n1,n2) #hold function values.

   print(n1) #print values

   print(n2) #print values

Output:

Enter first number :3

Enter second number :8

8

3

Explanation:

The explanation of the above python program can be given as:

  • In the python program we define a function that is "swap_values". This function takes two integer values that is "user_val1 and user_val2" as a parameters and returns variable values that is "user_val2 and user_val1".
  • Then we use a constructor in this we define two variable that is "n1 and n2" these variable are use to take user-input from the user and pass the value into the function.  
  • To hold the value of the function we use n1 and n2 variable and print these variable value.
