Delete vowels

The English alphabets {a,e,i,o,u} are called as vowels. Here, we are going to delete all the vowels found in the string given by the user.

Logic:

We will traverse each character, if it is a consonant, then we will add it to a new string, else ignore it. Then we’ll copy the new string to the original string.

Algorithm:

Input a string.
Run a for loop to traverse the given string.
Check each character is a vowel or not, using the function.
Copy the contents of the new string in the old string.
Print the modified string

Code:
\n

#include <iostream>\r\n#include <cstring>\r\nusing namespace std;\r\nint vowel(char c)\r\n{\r\n\tif (c == 'a' || c == 'A' || c == 'e' || c == 'E' || c == 'i' || c == 'I' || c =='o' || c=='O' || c == 'u' || c == 'U')\r\n\t\treturn 1;   // a vowel\r\n\telse\r\n\t\treturn 0;   // not a vowel\r\n}\r\nint main()\r\n{\r\n\tstring str,newstr;\r\n\tcout<<\"Enter a string: \";\r\n\tgetline(cin,str);\r\n\tint len=str.length();\r\n\tint j=0;\r\n\tfor(int i = 0; i<len; i++)\r\n\t{\r\n\t\tif(vowel(str[i]) == 0)\r\n\t\t{\r\n\t\t\tnewstr[j] = str[i];    //newstr is string without vowels\r\n\t\t\tj++;\r\n\t\t}\r\n\t}\r\n\tnewstr[j] = '\\0';  //terminate the string\r\n\tstrcpy(str, newstr);    //copying the new string,  \r\n\tcout<<\"Modified String:\"<<str;\r\n\treturn 0;\r\n}

Output:

\r\nEnter a string: Vowels will be deleted\n

Modified string: Vwls wll b dltd\r\n
