strcpy
strcpy copies a string from one array into another. Listing 4-8 provides an example.
Listing 4-8. strcpy
#include <iostream>
using namespace std;
int _tmain(int argc, _TCHAR* argv[])
{
char* cStyleString1 = "CStyleString";
char cStyleString2[13];
strcpy(cStyleString2, cStyleString1);
cout << cStyleString2 << endl;
return 0;
}
It's important to note that cStyleString2 contains enough space to store the 12 characters of the
string literal plus an extra character for the null terminator.
strcat
strcat allows us to join, or concatenate, two strings. Listing 4-9 provides an example.
Listing 4-9. strcat
#include <iostream>
using namespace std;
int _tmain(int argc, _TCHAR* argv[])
{
char cStyleString1[13];
strcpy(cStyleString1, "CStyle");
char* cStyleString2 = "String";
strcat(cStyleString1, cStyleString2);
cout << cStyleString1 << endl;
return 0;
}
cStyleString1 must have enough space to store the combined string, therefore we create an array
with space for 13 characters. We then use strcpy to copy "CStyle" into this array. strcat is used to
copy "String" into the end of cStyleString1 from cStyleString2 .
