i wrote a program that plays this game we do in math class. you are given five numbers, say 5 7 3 9 and with thoes number you must get to a fith number say 11. so you think about it and say 7+3=10, 10/5=2, 2+9=11. so i wrote this program with a 3 funtions i made. i taught myself c++ over the summer and it is my first language so im not that good. any way it seemed that my computer skiped over the funtions. just ignored them. a simple example of what i was doing.
Code:
main(){
int c;
funtion();
cout<<c<<endl;
}
funtion(){
c=1;
return();
}
when i should have been doing this
Code:
main(){
int c;
c=funtion();
}
funtion(){return 1;
}
so i fixed this but now i dont get any out put at the end i looked for bout 3 hours for something wrong i cant find anything. could some one please help me. thank you very much. and here is my code
Code:
#include <iostream>
#include <math.h>

if someone could give me a nudge it the right diretion that would be great. thank you very much
