I have to count the vowels of evey word in a given text. My attempt :
#include <iostream>
#include <string.h>
using namespace std;
char s[255], *p, x[50][30];
int c;
int main()
{
cin.get(s, 255);
cin.get();
p = strtok(s, "?.,;");
int n = 0;
while (p)
{
n++;
strcpy(x[n], p);
p = strtok(NULL, "?.,;");
}
for (int i = 1; i <= n; i++)
{
c = 0;
for (int j = 0; j < strlen(x[i]); j++)
if (strchr("aeiouAEIOU", x[i][j]))
c++;
cout << c << " ";
}
return 0;
}
PS: I know that my code is a mix between C and C++, but this is what I am taught in school.
This is my solution:
#include <iostream>
#include <string.h>
using namespace std;
int main()
{
char s[255];
int n,i,counter=0;
cin.get(s,255);
for(i=0; i<=strlen(s)-1; i++)
if(s[i]=='a' || s[i]=='e' || s[i]=='i' || s[i]=='o' || s[i]=='u') counter++;
cout<<counter;
return 0;
}
If you have a vowel( a, e, i, o or u) you are adding up to the counter. You can also use strchr but this is a more simple, understandable method.
Case closed in the comments.
However, for the fun, I propose you another variant that avoids to use the terrible strtok()
, doesn't require a risky strcpy()
, and processes each input character only one.
As you are bound to your teacher's mixed style and apparently are not supposed to use c++ strings yet, I also respected this constraint:
const char separators[]=" \t?.,;:"; // I could put them in the code directly
const char vowels[]="aeiouyAEIOUY"; // but it's for easy maintenance
int vowel_count=0, word_count=0;
bool new_word=true;
char *p=s;
cout << "Vowels in each word: ";
do {
if (*p=='\0' || strchr(separators,*p)) {
if (!new_word) { // here, we've reached the end of a word
word_count++;
cout << vowel_count << " ";
vowel_count = 0;
new_word=true;
} // else it's still a new word since consecutive separators
}
else { // here we are processing real chars of a word
new_word=false; // we have at least on char in our word
if (strchr(vowels, *p))
vowel_count++;
}
} while (*p++); // It's a do-while so not to repeat the printing at exit of loop
cout << endl<<"Words: "<<word_count<<endl;
