i don't think that is the word for this but i want to set a variable to add one to itself after an if statment. i have tried:
points = points+1
points++
points+1
points = points++
and they don't work.
this is what im trying to do:
code: |
cout << "is the donkey going north?" << endl;
cin >> ans;
if (ans =="y")
{
points++;

lame communist exposer:
code: |
cout << "Have you ever felt pride in hearing the exclamation of Mother Russia?" << endl;
cin >> ans;
if (ans == "y")
{
points ++;
}
cout << points << endl;
cout << "Have you ever read the Communist Manifesto, and thought it very enlightening?" << endl;
cin >> ans;
if (ans == "y")
{
points++;
}
cout << "Have you ever visited sovietempire.com?" << endl;
cin >> ans;
if (ans =="y")
{
points+1;
}
cout << "Communist Answers Communicated: ";
cout << points; |
it compiles and everything, but it when it says
Communist Answers Communicated, it says 0 instead of what should be there, such as 1, 2, or 3 depending on the answer given. |

My guess is that the problem is probably with
Quote: ans == "y"
how was ans declared:
1. char ans;
use ans =='y'
2. char ans[2];
use strcmp(ans,"y")==0
3. string ans;
ans == "y" // i.e. my guess was wrong |

wow, thanks mckenzie, that was the problem, i had the variable as:
char points[1];
for some reason, i forgot to take out the one cause that is useless i think for my purpose cause char is already 1.
it works now |
