hi, i have made a little hello world console app. here is the code: #include <stdio.h> float myVar = 1; int main () { printf( "hello world" ); getchar(); return 0; } what i want now is to print the value of myVar instead of "hello world". how do i do that? thanks

#include <iostream>

....

int i = 10;
float f = 3.14;
std::cout << "Hello world" << " " << i << " " << f << std::endl;



printf is C, so it's not generally recommended in C++;


int i = 10;

printf("%d", i);
