Question

Write a program called problem4.cpp that creates a histogram of the temperature values over the past year. The temperature values ranges from 0 to 25 degrees, and the program should ask the use to input the number of days in the past year where the temperature was of each of these values. After the user inputs this data, the program should draw a histogram of these temperatures using the char ‘*’ and output the mode temperature (the temperature that occurred most frequently over the past year)

Answer 1

Code:

#include<iostream>

using namespace std;

int main(){
   int day,max;
   int temp;
   int freq[26]={0};
   cout<<"Enter No of Days: ";
   cin>>day;
  
   for(int i=1;i<=day;i++){
       cout<<"Enter Temprature(0-25) for day "<<i<<": ";
       cin>>temp;
       freq[temp]++;
      
   }
   cout<<endl;
   for(int i=0;i<26;i++){
       cout<<i<<": ";
       for(int j=0;j<freq[i];j++){
           cout<<"*";
       }
       cout<<endl;
   }
   max=0;
   for(int i=0;i<26;i++){
   if(freq[i] > max){
       max=i;
   }  
   }
  
   cout<<endl<<"Max frequency temprature is: "<<max;
}

Output:
