Thread: my program does nothing

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>
using namespace std;
float comp (float a, float b, int t);
int perm (int varo, int ea, int eb, int ec, int ed);
int computation (float sa, float sb, float sc, float sd, float se);

	int ec = 0;
	int ed = 0;
	float pa = 0;
	float pb = 0;
	float pc = 0;
	float pd = 0;

	cout<<"type in the first four numbers press enter after each one"<< endl;
	cin>> na;
	cin>> nb;
	cin>> nc;
	cin>> nd;
	cout<<"now enter the number you want to get"<< endl;
	cin>> ne;

	k = 0;
	while (k<=4){
		k ++;
		chance = perm (k, ea, eb, ec, ed);
		if (chance==1){
			ea = 1;

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