Number of consonants

[Answerx]

Help me please! I want to make a program that displays the word with the maximum number of consonants from a sentence.

[Mathhead200]

Can you explain that again, or give an example?

[webJose]

-Read the sentence from somewhere (user input, text file, etc.).
-Split the sentence into words.
-Count consonants for each word and output the one with the most consonants.

[Answerx]

For example I type a sentence "I am eating my lunch",as you can see the word "lunch" has the most consonants, so I have to show this word.

try this:

#include <iostream>
#include <string>

void maxConsonants(std::istream& stream)
{
	static std::string consonants = "zrtpqsdfghjklmwxcvbn";
	std::string build = "";
	int c = 0;
	int count = 0;

	int max = 0;
	std::string smax = "";

	while ((c = stream.get()) != -1)
	{
		if (c == ' ')
		{
			if (!build.empty() && count > max)
			{
				smax = build;
				build = "";
				max = count;
				count = 0;
			}
			continue;
		}
		if (consonants.find(c) != consonants.npos)	
			++count;
		build += c;
	}
	if (count > max)
		smax = build;
	std::cout << smax;
}

I may forget some consonants

@aquaz: Don't just give out code like that. Too many people will simply take it and leave, learning nothing.

@aquaz: Is this C++? I don't understand this code. Why you didn't use char variables to insert the sentence?

[Pravesh Koirala]

@Answerx: Yup that is C++, I think you are asking for C. You should follow webjose's instructions but here are some more tip for finding the consonants in a given word:-

Use consonant (char array) = ""zrtpqsdfghjklmwxcvbn"
Assuming you have a variable "word" which contain the word which you want to check
Iterate through the word taking one char at a time. Use strstr to check whether it is a consonant or not and record it.
Then return the value from the function. Easy enough!!

Ok I will explain what i am doing:
First, the parameter std::istream& let you perform the function on any stream: a string, a file, stdin... . For example if you want to call the function on a string, you just have to domaxConsonants(std::istringstream("test test2"), on input you domaxConsonants(std::cin)... .
In the while test(l.14), I retrieve the characters from the stream an test if it is the end(-1).
And in the while body, three cases:
1) the char is a space (l.18): I test if the last string builded have the most consonants and if yes if put it as the max string
2)the char is a consonant(l.27): i increment the max count

At the end I output the max string, smax.

Here is a variant made by me, please help me find the mistake.

#include <stdio.h>
#include <stdio.h>
#include <conio.h>
#include <math.h>
#include <iostream.h>
#include <string.h>


void main()
{char cons[21]={'b','c','d','f','g','h','j','k','l','m','n','p','q','r','s','t','v','w','x','y','z'};
char s[30],x[30][30],z[30]; int i,j=0,k=0,r,f,n,poz,c,max;
clrscr();
printf("Type sentence:");
gets(s);n=strlen(s);r=0;k=0;

for(i=0;i<n;i++){
if((s[i]!=' ')&&(s[i]!='.')){x[r][k]=s[i];k++;}
if((s[i]==' ')||(s[i]=='.')){x[r][k]='\0';r++;k=0;}}

for(i=0;i<r;i++)
for(j=0;j<strlen(x[i]);j++)
for(k=0;k<21;k++)
if(x[j]==cons[k]) {c++;}
z[i]=c;
max=z[0]; poz=0;
for(i=0;i<r;i++)
if(max<z[i])
{max=z[i];poz=i;}
puts(x[poz]);}

Is there somebody who can help me? Please, I'm desperate.

This sounds like homework, so I'll give you an obfuscated example that your teacher will know you didn't write:

int countConsonants(string s) {
    int consonants = 0;
    for(int i = 0;i < s.length();i++) {
        consonants += (s[i] == 'a')?0:((s[i] == 'e')?0:((s[i] == 'i')?0:((s[i] == 'o')?0:((s[i] == 'u')?0:((s[i] == ' ')?0:1)))));
    }
    return consonants;
}

EDIT: Tested now. It works. Updated to not count spaces.
