C++ help!

In addition to the current program,

** Write a function named percentHeads that takes an integer number of coin tosses as a parameter and then returns the percentage of times the coin lands on heads when throwing the coin that many times. Represent heads as a 0, and tails as a 1.

Seed your random number generator with srand(4444)

Here is an example run of the program as it would look in cloud9:

#include <iostream>
using namespace std;

int add(int a, int b){
return a+b;
}

int subtract(int a, int b){
return a-b;
}

int main() {
int num1 = 0;
int num2 = 0;
int sum = 0; //sum of numbers
int diff = 0; //difference of numbers

cout << "Enter the first integer: ";
cin >> num1;
cout << "Enter the second integer: " << endl << endl;
cin >> num2;

cout << "First Integer: " << num1 << endl;
cout << "Second Integer: " << num2 << endl << endl;

// Call add function
sum = add(num1, num2);

// FIXME (4) Call subtract function
diff = subtract(num1, num2);

// FIXME (6) Output result of num1 + num2
cout << num1 << " + " << num2 << " = " << sum << endl;

// FIXME (8) Output result of num1 - num2
cout << num1 << " - " << num2 << " = " << diff << endl;

return 0;
}

Explanation / Answer

#include <iostream>
#include <stdlib.h>
using namespace std;

int main() {
   int num = 0;
   int i;
   int head=0,tail=0;
   srand(4444);
   cout << " Enter the number of times you want to toss the coin:";
   cin >> num;
  
   for (i = 1; i<=num;i++){
       if (rand() % 2 == 1){
           head++;      
       }
       else{
           tail++;  
       }
          
   }
   cout <<"Heads came up "<< (head*100)/float(num) << "% of the time. ";
}
