我如何随机输入字符串中的数字？

Question

我试图在一个字符串中设置一个随机数，但是idk我怎么能让程序知道我想要随机数而不是字母n。

我正在使用visual studio 2008，Windows Forms C ++

System::Drawing::Font ^Fuente = gcnew System::Drawing::Font("Arial Black",50);
System::Random ^r = gcnew System::Random(System::DateTime::Now.Ticks);
char n=r->Next(1,100);
buffer->Graphics->DrawString("n",Fuente,System::Drawing::Brushes::WhiteSmoke,50,50);,50);

Answer 1

System::Drawing::Font ^Fuente = gcnew System::Drawing::Font("Arial Black",50);
System::Random ^r = gcnew System::Random(System::DateTime::Now.Ticks);
int n=r->Next(1,100);
buffer->Graphics->DrawString(n.ToString(), Fuente, System::Drawing::Brushes::WhiteSmoke,50,50);,50);

可能是你的目标

Answer 2

在绘制字符串时使用引号 - 这是一个字符串文字。

您应该使用stdlib.h itoa函数将您的数字转换为字符串。

char number[3];
int n = r->Next(1,100);
itoa(n, number, 10); //number to convert, string to save value in, base
buffer->Graphics->DrawString(number,Fuente,System::Drawing::Brushes::WhiteSmoke,50,50);,50);
