string replace and erase/insert

**divineleft** · 07-04-2006

first of all, is it possible to do an array of strings? Either that or an array of character sequences (if that's the same thing).

Code:

string start0 = (" _____________ ");
string start1 = ("|   ___       |");
string start2 = ("|  |_ _|      |");
string start3 = ("|             |");
string start4 = ("|       | |   |");
string start5 = ("|_______| |___|");

string  *hello[5];
hello[0] = &start0;
hello[1] = &start1;
hello[2] = &start2;
hello[3] = &start3;
hello[4] = &start4;
hello[5] = &start5;


*hello[y].replace (x,1, "X" );

^where the variable y and x are input by the user. It wont let me use a pointer there. Is there any other alternative?

How about
hello[y]->replace(...)

It is possible to have an array of strings. However, you may find it better to have a std::vector<std::string>

Code:

// create a vector of 6 default initialised strings
std::vector<std::string> start(6);
// populate the strings in the vector with the desired values
start[0] = " _____________ ";
start[1] = "|   ___       |";
start[2] = "|  |_ _|      |";
start[3] = "|             |";
start[4] = "|       | |   |";
start[5] = "|_______| |___|";

^where the variable y and x are input by the user. It wont let me use a pointer there. Is there any other alternative?

It depends on what exactly you want to do, but with this vector of strings you may be able to write:

Code:

start[y].replace(x, 1, "X");
