Question

C++

2) Create a program that does all of the following: Create 100 random int numbers from 48-84 Puts them in an array called height Counts how many of each there were Sorts the numbers from high to low If short 48-60, average- 61-70, tall- 71-74 and big is any them above 84, count how many is each group Print the results from the last part as a bar graph short average tall big

Answer 1

Code: (as the array contains random numbers, output will differ at every run)

#include <iostream>
#include <cstdlib>
#include <ctime>
using namespace std;
  
int gcd(int a, int b)
{
if (a == 0)
return b;
return gcd(b % a, a);
}
  
int findGCD(int arr[], int n)
{
int result = arr[0];
for (int i = 1; i < n; i++)
result = gcd(arr[i], result);
  
return result;
}

int index(int num){
if(num<61) return 0;
else if(num<71) return 1;
else if(num<75) return 2;
else return 3;
}
  
int main()
{
char category[4][10] = {"short ", "average ", "tall ", "big "};
int random_numbers[100];
int scale[4] = { 0, 0, 0, 0 };
int i, temp, gcd;
  
srand(time(0));
  
for (i = 0; i < 100; i++) {
temp = (rand() % (37)) + 48;
random_numbers[i] = temp;
scale[index(temp)]++;
}
  
gcd = findGCD(scale, 4);
  
for(i = 0; i < 4; i++){
scale[i]/=gcd;
cout<<category[i];
while(scale[i]--){
cout<<'*';
}
cout<<'\n';
}
  
return 0;
}

Output:
