combine user input variable with normal variable

[niskin]

Hi I want to combine these variables:

char computera[10]; //this variable contains input from the user
char path[]= "\\\\";
char location[] = "\\C$\\Windows\\System32\\chat.txt";

The order I want them in is:

path[] + computera[10] + location[]

I have tried this to get the first two variables joined together:

strcat(path,computera);

However, when I tried to print this to check that it had worked, some weird symbols came up.

Any ideas?

you have to create a buffer large enough to hold everything and then strcat/strcpy/whatever into that

char buff[1024] = {0}; //1024 should be big enough!
...
...
strcpy( buff, path );
strcat( buff, computera );
strcat( buff, location )

This is for C:

char buff[1024] = {0}; //1024 should be big enough!
...
...
strcpy( buff, path );
strcat( buff, computera );
strcat( buff, location )

This is how it's done in C++:

string computera; //this variable contains input from the user
string path("\\\\");
stirng location("\\C$\\Windows\\System32\\chat.txt");
 
//The order I want them in is:
 
path= path + computera + location;
 
//and you are done.
