Question

c++ program

Exercise #1: Index of the Minimum Write a function main() that prompts the user to input a positive integer n, then calls the function generate() which generates n random numbers in the range [11, 217] inclusive. The function main() also calls the function indexMin() which finds the smallest random number and its index. The function main() prints the random numbers and the two values produced by the function indexMin(). Sample input/output: How many integers: 9 The 9 random numbers are: 93 146 111 The minimum 70 was located at index 3 70 196 191 196 188 108

Answer 1

C++ program:

#include<iostream>

using namespace std;

// Defining function generate to generate random number

void generate(int* arr , int n){

for(int i = 0; i < n; ++i){

// generating a random number between 11 and 217

arr[i] = (rand() % (217 - 11 + 1) + 11) ;

}

}

// Function to return index and minn value

pair<int , int> indexMin(int* arr , int n){

int index = 0 , minValue;

for(int i = 0; i < n; ++i){

if(arr[i] <= arr[index]){

index = i;

}

}

minValue = arr[index];

pair<int , int> p = {minValue , index};

return p;

}

// Writing main function

int main(){

// Declaring variable to store n

int n;

// Declaring an array to store random array

int arr[100];

// Asking the user to input n

cout << "How many integers: " ;

cin >> n;

// Calling generate function

generate(arr , n);

// Calling indexMin function

pair<int , int> p = indexMin(arr , n);

// Displaying array generated

cout << "The " << n << " random integers are: ";

for(int i = 0; i < n; ++i){

cout << arr[i] << " ";

}

cout << endl;

// dispalying minimum value and its index

cout << "The minimum " << p.first << " was located at index " << p.second << endl;

return 0;

}

OUTPUT:

How many integers: 9 The 9 random integers are: 183 126 155 36 178 126 48 104 206 The minimum 36 was located at index 3
