copying a string
Author
ok...should be simple enough
how do i copy one string to another
for example, if i have
string1 = "Hello";
string2 = "Goodbye";
and i want to copy string2 to string1, iwould think
strcpy(string1, string2);
but my compiler REALLY doesnt'' like this...what am i supposed to use
I assume this is in c++
char string1[20];
strcpy(string1, "Hello");
char string2[20];
strcpy(string2, "Goodbye");
strcpy(string1, string2);
Move toSTL:
#include using std::string;string string1, string2, string3;string1 = "Hello", string2 = "Goodbye";string3 = string1; string3 += string2;
actually C++ would be
in C you can eighter use strcat or sprintf
remember the brackets [] to make a char array instead of a char single char variable
#include std::string string1("Hello");std::string string2("Goodbye");std::string string3;string1+=string2; // if you want to append string1 to string2string3 = string1+string2; // if you want string 1 and 2 untouched in C you can eighter use strcat or sprintf
char string1[] = "Hello";char string2[] = "Goodbye";char string3[255] = "";// strcat version:strcat(string3,string1); // append string 1 to string 3 (empty)strcat(string3,string2); // append string 1 to string 3 (containing string 1)// sprintf version:sprintf(string3,"%s%s",string1,string2);//in both cases string2 ends up with the result you want. remember the brackets [] to make a char array instead of a char single char variable
sorry for the double post, came up wrong and as anon, cant change it
