Question

I need to write a C++ program that will generate random numbers between the ranges of your own choice and within the random numbers, indicate the maximum, minimum and the average of the random numbers.

Answer 1

C++ code:

#include <iostream>
#include <stdlib.h>
#include <time.h>

using namespace std;
int generateRandom(int,int); // function declaration
void calculate(int[],int);

int main()
{
int ranNum,minRange,maxRange,i=0;
cout << "Enter the no.of random numbers : ";
cin >> ranNum;
int nums[ranNum];
cout << "Enter the range of random numbers : \n";
cin >> minRange >> maxRange;
cout << "Generated array : \n";
//while loop to generate random numbers by calling the function
while(i!=ranNum){
nums[i] = generateRandom(minRange,maxRange); // calling function
cout << nums[i] << " " ;
i++;
}
calculate(nums,ranNum); // for calculating avg, min & max
return 0;
}

void calculate(int nums[],int ranNum){
int max=nums[0],min=nums[0],avg,i=0,add=0;
for(i=0;i<ranNum;i++){
if(nums[i] < min){
min = nums[i];
}
else if(nums[i] > max ){
max = nums[i];
}
add = add+nums[i];
}
// printing the values
cout << "\nMIN : " <<min << " \t MAX : " <<max << " \t AVG : " <<add/ranNum << "\n";
}

int generateRandom(int minRange,int maxRange){
       int r = (rand() % (maxRange-minRange)) + minRange; // random number generator with ranges.
   return r;
}

OUTPUT:
