To show: How to print various C++ data types using cout method in C++ programming
// using cout from iostream header file
#include <iostream>
using namespace std;
int main(void)
{
cout<<"Hello there.\n";
cout<<"Here is 7: "<<7<<"\n";
// other than escape sequence \n used for new line is endl
cout<<"\nThe manipulator endl writes a new line to the screen.\n"<<endl;
cout<<"Here is a very big number:\t" << 10000 << endl;
cout<<"Here is the sum of 10 and 5:\t" << (10+5) << endl;
// simple or auto type casting, from int to float
cout<<"Here's a fraction number:\t" << (float) 7/12 << endl;
// another type casting, from int to double
cout<<"And a very very big number:\t" << (double) 7000 * 7000<< endl;
cout<<"\nDon't forget to replace existing words with yours...\n";
cout<<"What a lame programmer!\n";
return 0;
}
Output example:
Hello there.
Here is 7: 7
The manipulator endl writes a new line to the screen.
Here is a very big number: 10000
Here is the sum of 10 and 5: 15
Here's a fraction number: 0.583333
And a very very big number: 4.9e+007
Don't forget to replace existing words with yours...
What a lame programmer!
