Question

Write code to perform the following steps for an array of integers Declare an array of100 integers Have the user enter a value for each element in the array Find the location in the array of the largest integer value Write out the largest value and the array location where it was found (i.e, The largest value is 95, which was found in position 7) Vectors of doubles Declare a variable that will be a vector of doubles (unknown size) Store every positive integer from 2 to 100 (50 values) into the vector Change the first element in the vector by subtracting 1 from it Write out all of the data in the vector separated by spaces

Explanation / Answer

Question 4:

Program:

#include<iostream>
using namespace std;

int main()
{
    int array[100]; // Declaring array of 100 integers
    //reading 100 inputs from user
    for(int i=0;i<100;i++) {
        cin >> array[i];
    }
    //Assgining Default value for maxValue as first array value
    int maxValue = array[0];
    //Assgining Default value for maxIndex as first index
    int maxIndex = 0;
  
    //Logic to find max value
    for(int i=1;i<100;i++) {
        if(maxValue<array[i]) { // if current value is greater than maxValue then update MaxValue and MaxIndex
            maxValue = array[i];
            maxIndex = i;
        }
    }
    cout << "The largest value is " << maxValue << ", which was found at position " << maxIndex;
  
    return 0;
}

Sample Input:

Sample Output:

The largest value is 100, which was found at position 99.

Question 5:

#include<iostream>
#include<vector>
using namespace std;

int main()
{
    vector<double> VectorOfDoubles; // Declaration of Vector Doubles
  
    for(int i=2;i<100;i++) {
        VectorOfDoubles.push_back(i); // pushing positive numbers to vector
        if(VectorOfDoubles.size()==50) //push only 50 numbers
            break;
    }
    VectorOfDoubles[0] -= 1; //Subtracting 1 from first element
  
    //printing all the data in VectorOfDoubles with space
    for(int i=0;i<VectorOfDoubles.size();i++) {
        cout << VectorOfDoubles.at(i) << " ";
    }
    return 0;
}
