Check vowels

In this example, we’ll find the vowels in the string provided by the users.

Logic: Here we’ll take an array of size 5 such that, its each index stores the count of a vowel. Then, we search the vowels from the string and increment the value at the particular position of the array.

Algorithm:

Take a string as input.
Declare an array of size 5.
Traverse the string and print the count array.

Code:
\n

#include <iostream>\r\n#include <string>\r\nusing namespace std;\r\nint vowel(char c)\r\n{\r\n\tswitch(c)\r\n\t{\r\n\t\tcase 'a' :\r\n\t\t\t{return 0;break;}\r\n\t\tcase 'A' :\r\n\t\t\t{return 0;break;}\r\n\t\tcase 'e':\r\n\t\t\t{return 1;break;}\r\n\t\tcase 'E':\r\n\t\t\t{return 1;break;}\r\n\t\tcase 'i' :\r\n\t\t\t{return 2;break;}\r\n\t\tcase 'I':\r\n\t\t\t{return 2;break;}\r\n\t\tcase 'o':\r\n\t\t\t{return 3;break;}\r\n\t\tcase 'O':\r\n\t\t\t{return 3;break;}\r\n\t\tcase 'u' :\r\n\t\t\t{return 4;break;}\r\n\t\tcase'U':\r\n\t\t\t{return 4;break;}\r\n\t\tdefault:\r\n\t\t\t{return 5;break;}\r\n\t}\r\n}int main()\r\n{\r\n\tstring str;\r\n\tint count[5]={0},x;\r\n\tcout<<\"Enter a string: \";\r\n\tgetline(cin,str);\r\n\tint len=str.length();\r\n\tfor(int i = 0; i<len; i++)\r\n\t{\tx=vowel(str[i]);\r\n\t\tif(x<5)\r\n\t\t\tcount[x]+=1;\r\n\t}\r\n\tcout<<\"\\n a:\"<< count[0];\r\n\tcout<<\"\\n e:\"<<count[1];\r\n\tcout<<\"\\n i:\"<<count[2];\r\n\tcout<<\"\\n o:\"<<count[3];\r\n\tcout<<\"\\n u:\"<<count[4];\nreturn 0;\n
\n}

Output:

\r\nEnter a string: aeiouaeiou\r\na:2\r\ne:2\r\ni:2\r\no:2\r\nu:2\r\n
