Dada una string que consta de alfabetos y otros caracteres, elimine todos los caracteres que no sean alfabetos e imprima la string así formada.
Ejemplos:
C++
// CPP program to remove all the
// characters other then alphabets
#include <bits/stdc++.h>
using namespace std;
// function to remove characters and
// print new string
void removeSpecialCharacter(string s)
{
for (int i = 0; i < s.size(); i++) {
// Finding the character whose
// ASCII value fall under this
// range
if (s[i] < 'A' || s[i] > 'Z' &&
s[i] < 'a' || s[i] > 'z')
{
// erase function to erase
// the character
s.erase(i, 1);
i--;
}
}
cout << s;
}
// driver code
int main()
{
string s = "$Gee*k;s..fo, r'Ge^eks?";
removeSpecialCharacter(s);
return 0;
}
Java
// Java program to remove all the characters
// other then alphabets
class GFG
{
// function to remove characters and
// print new string
static void removeSpecialCharacter(String s)
{
for (int i = 0; i < s.length(); i++)
{
// Finding the character whose
// ASCII value fall under this
// range
if (s.charAt(i) < 'A' || s.charAt(i) > 'Z' &&
s.charAt(i) < 'a' || s.charAt(i) > 'z')
{
// erase function to erase
// the character
s = s.substring(0, i) + s.substring(i + 1);
i--;
}
}
System.out.print(s);
}
// Driver code
public static void main(String[] args)
{
String s = "$Gee*k;s..fo, r'Ge^eks?";
removeSpecialCharacter(s);
}
