C++ :: Convert A Value Into A String?

May 21, 2013

I would like to convert a value into a string, and extract a value from a string. And then call these functions in the main.

template<class T>
string toString (T value) // convert a value into a string {
stringstream ss;

[Code[ .....

Are above functions correct? And how should I call in main?

int main() {
const int SIZE=10;
toString<int> intValue(SIZE); //seems not right
toString<double> doubleValue(SIZE); // seems not right
}

C++ :: Convert Int Array To String

Nov 5, 2013

I'm trying to convert int x and y arrays to string using a sample code found online.

string Square::int2string (int x[]) {
string returnstring = "";
for (int i=0; i < 4; i++) {
returnstring += itoa(x[i]);
return returnstring;
}
}

but hit with the following error.

Square.cpp:30:8: error: prototype for ‘std::string Square::int2string(int*)’ does not match any in class ‘Square’ Square.h:21:10: error: candidate is: std::string Square::int2string()

I declared the following in header file.

string int2string();

The error is due to variable type does not match. Is there a better way to convert int array to string?

What I'm trying to achieve is a string printed in the following manner:

Point[0] (x1,y1)
Point[1] (x2,y2) and so on.

byte offset 2, new_text_sz = 5
11C
byte offset 3, new_text_sz = 5
