To be frank I don't understand the working of this program.. please help me understand it,wont you?

#include<iostream.h>
#include<conio.h>
#include<string.h>
void main()
{
char line[80];
 
int k,len,vow,cons,sp;
cout<<"Enter the string ";
cin.getline(len i,80);
for(i=0;line[len]!=10;len++)
{
if (line[k]!=" ")
if(line[k]=="A"||line[k]=="E"||line[k]=="I"||line[k]=="O"||line[k]=="U"||line[k]=="a"||line[k]=="e"||line[k]=="o"||line[k]=="u");
vow++;
 
else if(( line [k]>='A'&&line[k]<='Z')||(line[k]>='a'&&line[k]<='z'))
cons++;
else sp++;
{
cout<<"no of vowels = "<<vow;
cout<<"number of constants ="<<cons;
cout<<"No of special characters ="<<sp;
getch();
}

Re: vowels,consonants and special symbols

first, format the code so that it uses proper indentation, and braces. That's the first step.

Re: vowels,consonants and special symbols

I guess the lessons of the previous thread haven't sunk in yet.
http://www.daniweb.com/forums/thread177531.html

Here's how to start

(Toggle Plain Text)

for(i=0;line[len]!=10;len++) {
}

Now press compile AND make sure it works.

Now add a few (not ALL) of your lines of code for the loop body, and try to compile it again.

Also learn to put { } on ALL your for loops, while loops, if statements and switch/case statements. It'll save you from spending ages finding yet another stupid bug because the code did what you asked it to, not what you thought you wanted.

}

I made some corrections.. now what is use of "i" ? Now there are 6 more errors.. It says that undefined symbol i ... Do reply buddies
