17.2 C++ Help

Question

So Im not sure what I am doing wrong but any time I input my code it just says there is no output. I don't know if I am just missing something silly or if it's not working. Getting frustrated and discouraged but I can't figure out what I'm doing wrong.
#include <iostream>

using namespace std;

int main()
{
int d = 0;
//your code goes here
for(d = 0; d == 200; d +=40){
cout << d << endl;
}

return 0;
}

Any help would be greatly appreciated as I am completely lost as to what I did wrong. Thank you in advanced!

Answer 1

In your code
When it runs for the first time it checks if d==200, which is false, as d is 0, so it terminates your loop without going inside and as a result does not print anything.

Just change you conditional value to
d<=200 then it will print values having incrementation of 40 upto 200.

Answer 2

Distance = speed * time

int speed = 40;
for(int hour=1; hour<=5; hour++){
cout<< speed*hour <<endl;
}

Answer 3

Ahhhh okay, I'll try that, thank you!
