Thread: Need help, would be very appreciated.

I need help, I am in the middle of writing a program of minigames for children. I have so far completed a crossword, draughts and tic tac toe. I am currently in the middle of making a hang man program I have the basics worte but I can't think of a way to do this - Have the user enter a sentance and the program will output the number of vowels in the sentance. For example if someone wrote "My name is John." It will output "There are 4 vowels." Could someone please help its the last game for my program.

Iterate through the string, letter by letter. If that letter is equal to a, e, i, o, or u, then increment your vowel counter.

Hopefully you don't have to handle the letter 'y'.

I really don't know how to do that though, I'm new to C programming and I havn't come across this yet.

Yes you could do something like this

1. After the user enters the sentence make a character pointer point to the first character of the string.
2. Then iterate through while you reach the end but with each iteration you check maybe using switch block
2.1 if the alphabet is upper or lower case a,e,i,o,u
2.2 If it is a vowel then keep incrementing the count
2.3 if at the end of string('\0') terminate out this loop
3. Print the number of times you figured count was incremented in 2.2

#include <stdio.h>

void Main (void) {
char c;

printf("Enter a sentence:\n");

scanf("%c", &c);
while (c != ".") {
printf("%c\n", c);
scanf("%c", &c);
}

printf(".\n");
}
So far I have this but I don't know where to put the integer or counter or what to put, I really only started this this week as a hobby and this one is really frustrating me.

A string is just an array of chars. Iterate through it with a for loop:

Code:

int i;
for(i = 0; i < the_string_length; i++)
    // The letter is string[i]

So you've completed a game of crossword, draughts, and tic tac toe, but you can't manage to count the vowels in a string? Sorry, but your "game for children" is starting to sound like a homework question to me. Not that it matters, but it usually helps to be up-front about those sorts of things (and forgive me if I am wrong).

Im 28 and what homework would I be doing in July if I was in school? I appreciate you would hate kids doing this but I really only started this as a hobby.

You are obviously the same person who started this thread, and you obviously didn't read any of the replies to it.

Are you sure you wrote this code

[insert]

Code:

#include <stdio.h>

void Main (void) {
char c;

printf("Enter a sentence:\n");

scanf("%c", &c);
while (c != ".") {
printf("%c\n", c);
scanf("%c", &c);
}

printf(".\n");
}

characters are compared with a ' ' (single quote) and not double quotes. Comeon i just saw this code in one of the other posts as well. Be honest with what you want. No one is going to write the code for you dear.

I say that and used it but I started from scratch on the advice I recieved, here it is and if anyone could tell me if I'm doing anything wrong please point it out.

#include <iostream>
#include <string>

int main()
{
int a = 0, e = 0, i = 0, o = 0, u = 0;

std::cout << "Enter a line of text: ";
std::string lineOfText;
getline( std::cin, lineOfText );

for ( std::string::size_type letters = 0;
letters != lineOfText.size(); letters++ )
{
switch( lineOfText[letters] )
{
case 'a' : ++a; break;
case 'e' : ++e; break;
case 'i' : ++i; break;
case 'o' : ++o; break;
case 'u' : ++u; break;
}
}

std::cout << a << " a ";
std::cout << e << " e ";
std::cout << i << " i ";
std::cout << o << " o ";
std::cout << u << " u " << std::endl;

return 0;
}

Then I would just say I needed help in my work? This isn't a witch hunt

As I stated in your other thread, please use [code] tags.

Also, your new code works (and it seems to have changed from C to C++), so what's the problem?
