problem with strcpy while copying a 2d string into 1d string in dev c++

insert

Code:

---


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

using namespace std;

class dic
{
      char w[5][10];
      char m[5][10];
      char a[5][10];
     
      public:
            dic();
            void search();
            void setpos(int);
            void disrecsea(); 
            void display();
};

int j=0;

dic::dic()
{
                  strcpy(w[0],"first");
                  strcpy(w[1],"second");
                  strcpy(w[2],"third");
                  strcpy(w[3],"fourth");
                  strcpy(w[4],"fifth");
           
                  strcpy(m[0],"1");
                  strcpy(m[1],"2");
                  strcpy(m[2],"3");
                  strcpy(m[3],"4");
                  strcpy(m[4],"5");
           
                  strcpy(a[0],"6");
                  strcpy(a[1],"7");
                  strcpy(a[2],"8");
                  strcpy(a[3],"9");
                  strcpy(a[4],"10");
}

void dic::search()
{
    int i;
    char word[10];
    cout<<"\n Enter the word = ";
    cin>>word;
    for(i=0;i<5;i++)
    {
      if(stricmp(word,w[i])==0)
      {
        cout<<"\n Meaning = "<<w[i];
        cout<<"\n Antonym = "<<a[i];
        setpos(i);
      }
    }
    if(i==5)
    cout<<"\n NOT FOUND ";
}
           
void setpos(int i)
{
    char ch[10];
   
    strcpy(ch,w[j]); // this is where i am getting error
    strcpy(w[j],w[i]);
    strcpy(w[i],);
     
    strcpy(ch,a[j]);
    strcpy(a[j],a[i]);
    strcpy(a[i],ch);
   
    strcpy(ch,m[j]);
    strcpy(m[j],m[i]);
    strcpy(m[i],ch);
    j++;
}
             
void dic::disrecsea()
{
    cout<<"\n Recent searches \n";
    if(j==0)
      cout<<"\n No recent searches";
    for(int i=0;i<j;i++)
    {
      cout<<"\n Word    = "<<w[i];
      cout<<"\n Meaning = "<<m[i];
      cout<<"\n Antonym = "<<a[i];
      getch();
    }
}

void dic::display()
{
  for(int i=0;i,5;i++)

    if(choice=='y'||choice=='Y')
    goto top;
    return 0;
}

error:-'w' undeclared( first use this function )
how to resolve???????

You probably intend to be writing dic::setpos rather than setpos.

Code:

---

void dic::setpos(int i)
{
    char ch[10];
   
    strcpy(ch,w[j]); // this is where i am getting error
    strcpy(w[j],w[i]);
    strcpy(w[i],);
     
    strcpy(ch,a[j]);
    strcpy(a[j],a[i]);
    strcpy(a[i],ch);
   
    strcpy(ch,m[j]);
    strcpy(m[j],m[i]);
    strcpy(m[i],ch);
    j++;
}

You forgot to resolve your function with your class. Any special reason you are using char arrays and C functions in a C++ program? This isn't C++, you are making C with classes. You should look at implementing std::string and std::vector for this. It will make your program a lot easier to manage.

There are only a few reasons to use goto. THIS IS NOT ONE OF THEM. Think about your program and restructure accordingly, such as using a loop.

EDIT: None of your function calls will work either. May I suggest you look at CBoard - C++ Tutorials.

thank u all.Now its working.i can't believe how a silly mistake it was.there were some logical errors also but i corrected them and some others like calling member functions directly from main() and not using object.

I hope you fixed some of the things pointed out, as well.
