c++创建并输出不同类型的变量

#include iostream

#include string

using namespace std;

int main()

{

//创建变量
int myNum = 5;
float myFloatNum = 5.99;
double myDoubleNum = 9.98;
char myLetter = 'D';
bool myBoolean = true;
string myString = "Runoob";

//输出变量
cout << "int:" << myNum << endl;
cout << "float: " << myFloatNum << "\n";
cout << "double: " << myDoubleNum << "\n";
cout << "char: " << myLetter << "\n";
cout << "bool: " << myBoolean << "\n";
cout << "string: " << myString << "\n";

system("pause");
return 0;
