Functions .... very simple...


suppose i had to write a program for a math problem and it took 1000 lines of code..... but i must also do the math problem 3 times.....

Now 

1
2
3
4
5
6
7
8
 
void main(){

1000 lines 
+
1000 lines
+
1000 lines
}


3000 lines of crap , endless.


i can just make a function

1
2
3
 
void myMathSolution(){
1000 lines
}



then call it 5 times....

1
2
3
4
5
6
7
8
9
10
11
12
 
void main(){
myMathSolution();
myMathSolution();
myMathSolution();
myMathSolution();
myMathSolution();

// hell i can loop it 1000 more times 

for(int x = 1000; x>0;x --;)
myMathSolution();
)


look how small my code is and i solved the math problem a 1000 times...

plus i can copy paste the function in another program and run it again for another program in the future...

that is all a function really is for...

If you have over a hundred lines for any function, you're doing something very wrong or doing something that other functions could do. ;)

Hey iHateBooks. I modified your program to make it work correctly. That function void result (void) as to be a double. Here you go:
1
2
3
4
5
6
7

9
10
11
12
13

#include <iostream>
using namespace std;

double result(double);

int main(void)
{
	double celcius;

    cout << "Please input a celcius value: ";
    cin >> celcius;
    cout << celcius << " celcius is equal to " << result(celcius) << " fahrenheit!\n";
	system("PAUSE");
    return 0;
}

double result(double temp)
{
	double result;

    result = 1.8 * temp + 32;

	return result;
}

It took a thousand lines of code just for me to add two numbers once.... wonder what i did wrong :)
