how to copy

[pode]

hi all,

how do u copy a string to another string whithout using
strcpy()

sure if its possible use strcpy() but all i get is errors


i'm using 2 for loops like this


char temp[10];

for(cin>>ansver;ansver!='q';cin>>ansver)

for(int c=0;c<strlen(string);c++) //string is 10 slots
{




if(pointer[c]==answer) // pointer points to string

{
strcpy( temp[c], pointer[c]) // i thought something like this must
do the job. but i get errors
}} i know why i get errors but i dont know any other way to do this except memcpy() but that would'nt do
the job

Can you explain:

for(cin>>ansver;ansver!='q';cin>>ansver)

Can you explain:

code:--------------------------------------------------------------------------------
for(cin>>ansver;ansver!='q';cin>>ansver)
--------------------------------------------------------------------------------

yes it means


as long as ansver is not equal the letter q
ask for a new ansver


u dont see it very often huh?

No, I don't. Why not a WHILE loop?

(Not getting into that one again!)

Your first FOR loop has no start brace. A typo?

From my experience, (not that I've personally made this boo-boo, mind you! ), you might generate lots and lots of errors.

Thinking out loud.

Hello,

Copying a string in C++ is very easy:

#include <iostream>
#include <string>

using namespace std;

int main()
{
    string a = "Hello, world!";
    string b;

    // copy a into b
    b = a;

    cout << b << '\n';
}

That doesn't make sense to me. Try this instead:

char String1[32] = "Hello world!";
char String2[32] = "";

strcpy(String2, String1);

cout << String2;

And if you're not allowed to use strcpy, make your own:

void strcpy(char* Buffer, char* String)
{
   int Pos = 0;
   while(String[Pos] != '\0')
   {
      Buffer[Pos] = String[Pos];
      Pos++;
   }
   Buffer[Pos] = '\0';
}
