Well, in C++ and C strings are just arrays of chars. The array of chars uses the subscript operator([]) to access the char in the array. Simply loop through the string and check each char, if it's a vowel then do the work if it's a vowel, otherwise it's not. Eg for C++: // Loop through it. for(unsigned int x = 0; x < myString.length(); ++x){ if(myString[x] == 'a' || myString[x] == 'i') { // add more vowels if needed // ... } } If you're using cstrings(const char* or char*) you must use C functions. strlen, strcmp, etc. If using C++ it's recommended to use the std::string(found in ).

Simply loop through the string (remember, a string can be treated like an array of characters). If the char matches a, e, i, o or u, increment a vowel counter and continue.
