basic programing - printing a variables value [c++]
Author
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);
well for starters, use the cout function instead of printf
the syntax is
std::cout<<"string here";
or to display a variable you would do
std::cout<< variable name <<;
the syntax is
std::cout<<"string here";

std::cout<< variable name <<;
