Question

This assignment is about array operations. You need to count a specific items in an array. Steps to follow are here: • Create an array with 1000 items and fill it with random numbers from the range of -100, 100 (including - 100 and 100). . In your program asks user to enter a number, K. • Search this number and print the frequency (how many) of this K is found in the array. • Ask another number, and so one. The program keeps running until user enters a out-of-range (-100,100) number. An example run is given below. The array with 1000 random items is ready... Enter a number: -4 Frequency of -4: 54 Enter a number: 4 Frequency of 4: 15 Enter a number: 35 Frequency of 35: 8

Answer 1

Answer:-

CODE:-

#include <iostream>

using namespace std;
int getRandomNumber(int min, int max) {               //function to generate random number.
        return (rand() %
           (max- min + 1)) + min;
   }
int main()
{int a[1000],i;
   for(i=0;i<1000;i++)                         //generating 1000 random numbers
   a[i]=getRandomNumber(-100,100);
   int number;
   cout<<"Enter a number : ";
   cin>>number;
   int freq;
   while(number<=100 && number>=-100)                 //calculating frequency of number
   { freq=0;
        for( i=0;i<1000;i++)
        {if(number==a[i])
         freq++;
          
        }
        cout<<"frequency of "<<number<<": "<<freq<<endl;
        cout<<"Enter a number : ";
   cin>>number;
   }
  
  
    return 0;
}

   

CODE OUTPUT:-

1 2 #include <iostream> 3 4 using namespace std; 5. int getRandomNumber(int min, int max) { 6 return (rand() % 7 (max- min + 1)) + min; //function to generate random number. ها 8 9 //generating 1000 random numbers int main() 10 {int a[1000],i; 11 for(i=0;i<1000;i++) 12 a[i]=getRandomNumber(-100,100); 13 int number; 14 cout<<"Enter a number : "; 15 cin>>number; 16 int freq; 17 while(number<=100 && number>=-100) 18 { freq=0; 19 for(i=0;i<1000; i++) Sifoumber 1 - //calculating frequency of number input Enter a number : 4 frequency of 4: 8 Enter a number : 76 frequency of 76: 5 Enter a number : 101
