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

Output:

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