Locate the error

[spark]

well i am new to this and i've got tough assignments to deal with. i worked hard on this one but my compiler shows errors. please help me

For circular function you can use a char pointer that points to the char array.
Whereas for reverse function you can copy the string stored in one array into another array reversely and displays that string.
Your output can be similar with the following:

Enter a string:
circular

String in circular order:

circular
ircularc
rcularci
cularcir
ularcirc
larcircu
arcircul
rcircula

String in reverse order:

ralucric
----------------------------------------------


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

void circular(char[]);
void reverse(char[]);
const int size=10;

void main()
{
clrscr();
char str[size];
cout<<"Enter any word\n";
cin>>str;
cout<<"\nThe Circular of the word is :\n";
circular(str);
cout<<"\nThe Reverse of Word is : \n";
reverse(str);
getch();
}

void circular(char str[size])
{
char *sptr;
int i,j=0;

sptr=str;

while(*(sptr+1)!=0)
{
i=0;
sptr++;
j++;

cout<<sptr;

while(i<j)
{
cout<<str[i];
i++;
}

cout<<endl;
}
}

void reverse(char str[size])
{
int length = strlen(str);
for(int i=length-1; i>=0; i--)
cout<<str[i];
}

What were the compile time errors you got?

Possible sources of errors are
(1) some compilers do not have <conio.h> which you need for clrscr() and getch()
(2) some versions of <conio.h> do not have clrscr().
(3) many modern C++ compilers requre that main() returns an int

Fixing these problems gives (which should run with any C++ compiler)

#include<iostream.h>
//#include<conio.h>   // ** comment out
#include<string.h>
 
void circular(char[]);
void reverse(char[]);
const int size=10;
 
int main()
{
//clrscr();                               // ** comment out
char str[size];
cout<<"Enter any word\n";
cin>>str;
cout<<"\nThe Circular of the word is :\n";
circular(str);
cout<<"\nThe Reverse of Word is : \n";
reverse(str);
getchar();                          // ** changed from getch()
}
 
void circular(char str[size])
{
char *sptr;
int i,j=0;
 
sptr=str;
 
while(*(sptr+1)!=0)
{
i=0;
sptr++;
j++;
 
cout<<sptr;
 
while(i<j)
{
cout<<str[i];
i++;
}
 
cout<<endl;
}
}
 
void reverse(char str[size])
{
int length = strlen(str);
for(int i=length-1; i>=0; i--)
cout<<str[i];
}
 
 

when I now run the program I get
Enter any word circular

The Circular of the word is :
ircularc
rcularci
cularcir
ularcirc
larcircu
arcircul
rcircula

The Reverse of Word is :
ralucric
