Question

The language is C++

Write a program that uses the Rand_Int function to store 20 random die rolls for a 6-sided dice.

The program should print out the values horizontally then the program should call a user-defined function that will put () around any duplicate values beside each other. For example, if you rolled this:

3 1 1 3 6 1 5 3 2 6 2 2 2 4 6 1 3 6 6 3

Then you will have the above output, call your function which will produce this result:

3 (1 1) 3 6 1 5 3 2 6 (2 2 2) 4 6 1 3 (6 6) 3

Answer 1

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

void print(int array[20])
{
for(int i=0;i<20;)
{
if((i+1)<20&&array[i]==array[i+1])
{
int j=i;
cout<<"( ";
while(j<20&&array[j]==array[i])
{
cout<<array[j]<<" ";
j++;
}
cout<<") ";
i=j;
}
else
{
cout<<array[i]<<" ";
i++;
}
}
}

int main()
{
srand(time(0));
int array[20];
for(int i=0;i<20;i++)
array[i]= rand()%6+1;
for(int i=0;i<20;i++)
cout<<array[i]<<" ";
cout<<endl;
print(array);
return 0;
}
