appending two strings

[kip2847]

I need to add a string to another to form a sentence of some sort
i.e.
firststring + second string + third string
====================
How + are + you

so far here is my pusedo code:

char article = {"the", "a", "one", "some","any"};
char noun = {"boy", "girl", "dog", "town", "car"};
char verb = {"drove", "jumped", "ran", "walked","skipped"};
char preposition ={"to", "from", "over", "under", "on"};

// function will only take char so i copy into another point (easy for me to read)
char first = article[3];
*char sec = noun[2]l

//then i use the string function
strcat(first, sec);

at this point the program shuts down- not the type of error that gives me a log but the type that runs and then a win32 error occurs. from my understanding i am writing over other data bc of the use of the pointers... so how do i solve the problem.. i was thinking of creating aother char big enough to store the other smaller char but that seem like it didn't work same error occured .. any ideas will be apprciated

All your strings are constants (but you have a non-const pointer to them!), strcat() modifies the string in its first parameter, you cannot modify a constant. Another problem with strcat() is that the first string must have sufficient reserve space allocated to accommodate the concatenated string.

Furthermore this code is not real:

char first = article[3];
char sec = noun[2]l

for example is nonsense. And you cannot use an array initialiser on a simple pointer. This code won't compile. Post the real code if you want a definitive answer!

The simplest solution is to simply use C++ std::string objects:

include <string>

include <iostream>

include <cstdlib>

using std::string ;
using std::cout ;
using std::endl ;

int main()
{

const char article[] = {"the", "a", "one", "some","any"};
const char noun[] = {"boy", "girl", "dog", "town", "car"};
const char verb[] = {"drove", "jumped", "ran", "walked","skipped"};
const char preposition[] ={"to", "from", "over", "under", "on"};

string str = string(article[3]) + " " + string(noun[2]) ;
cout << str << endl ;;

system( "pause" ) ;
}
