C++ Exercises: Change every letter in a given string with the letter following it in the alphabet
C++ String: Exercise-2 with Solution
Write a C++ program to change every letter in a given string with the letter following it in the alphabet (ie. a becomes b, p becomes q, z becomes a).
Pictorial Presentation:
Sample Solution:
C++ Code :
#include <iostream>
#include <string>
using namespace std;
string change_letter(string str) {
int char_code;
for (int x = 0; x < str.length(); x++)
{
char_code = int(str[x]);
if (char_code == 122)
{
str[x] = char(97);
}
else if (char_code == 90)
{
str[x] = char(65);
}
else if (char_code >= 65 && char_code <= 90 || char_code >= 97 && char_code <= 122)
{
str[x] = char(char_code + 1);
}
}
return str;
}
int main()
{
cout << "Original string: w3resource";
cout << "\nNew string: " << change_letter("w3resource");
cout << "\n\nOriginal string: Python";
cout << "\nNew string: " << change_letter("Python");
return 0;
}
Sample Output:
Original string: w3resource New string: x3sftpvsdf Original string: Python New string: Qzuipo
