Given a string s, change the string s according to the rules provided below:
- Delete all the vowels from the string.
- Insert # in front of all the consonants.
- Change the case of all the letters of the string.
Examples:
Input : aBAcAba Output :#b#C#B Input :SunshinE!! Output :#s#N#S#H#N!!
Approach: First, create a new string by removing all the vowels from the given original string. Now, change the case of every alphabet in this string. Finally, add # in front of every alphabet in the string and this is required string.
Implementation:
C++
// CPP code to transform string #include <bits/stdc++.h> using namespace std;
// Function to change // character's case string change_case(string a) { int l = a.length();
for ( int i = 0 ; i < l ; i++)
{
// If character is lowercase
// change to uppercase
if (a[i] >= 'a' && a[i] <= 'z' )
a[i] = a[i] - 32;
// If character is uppercase
// change to lowercase
else if (a[i] >= 'A' && a[i] <= 'Z' )
a[i] = a[i] + 32;
}
return a;
} // Function to delete vowels string delete_vowels(string a) { string temp = "" ;
int l = a.length();
for ( int i = 0 ; i < l ; i++)
{
//If character is consonant
if (a[i] != 'a' && a[i] != 'e' &&
a[i] != 'i' && a[i] != 'o' &&
a[i] != 'u' && a[i] != 'A' &&
a[i] != 'E' && a[i] != 'O' &&
a[i] != 'U' && a[i] != 'I' )
temp += a[i];
}
return temp;
} // Function to insert "#" string insert_hash(string a) { string temp = "" ;
int l = a.length();
for ( int i = 0 ; i < l ; i++)
{
// If character is not special

(a[i] >= 'A' && a[i] <= 'Z' ))
temp = temp + '#' + a[i];
else

}
return temp;
} // Function to transform string void transformSting(string a)
