Answer:
Following are the correct python code to this question:
n1 = float(input('Input first number: '))#input first number
n2 = float(input('Input second number: '))#input second number
n3 = float(input('Input third number: '))#input third number
n4 = float(input('Input fourth number: '))#input fourth number
average = (n1+n2+n3+n4)/4 #calculate input number average
product = n1*n2*n3*n4 # calculate input number product
print('product: {:.0f} average: {:.0f}'.format(round(product),round(average))) #print product and average using round function
print('product: {:.3f} average: {:.3f}'.format(product,average)) #print product and average value
Output:

Explanation:
The description of the above python code can be defined as follows:
- In the above python program four variable "n1, n2, n3, and n4" is defined, in which we take input from the user end, and in these user inputs we use the float method, that converts all the input value in to float value.
- In the next step, two variable average and product are defined, that calculate all input numbers product, average, and hold value in its variable.
- In the last line, the print method is used, which prints its variable value by using a round and format method.
Answer:
#include<cstdlib>
#include<bits/stdc++.h>
#include<time.h>
using namespace std;
class Colors{
string colors[7];
public:
void setElement(int,string);
void printAllColors();
void printRandomColor();
};
void Colors::setElement(int index,string color){
colors[index] = color;
}
void Colors::printAllColors(){
cout << "Printing all the colors:\n";
for(int i=0;i<7;i++){
cout << colors[i] <<"\t";
}
}
void Colors::printRandomColor(){
srand (time(NULL));
int index = rand() % 7;
cout<< "\n\nThe random picked color:";
cout << colors[index] << endl;
}
int main(){
Colors color;
color.setElement(0,"red");
color.setElement(1,"orange");
color.setElement(2,"yellow");
color.setElement(3,"green");
color.setElement(4,"blue");
color.setElement(5,"indigo");
color.setElement(6,"violet");
color.printAllColors();
color.printRandomColor();
}
to get the random color we are using srand and rand function. we are using time as seed to srand() function,because every time the time is changed. And based on that we are using rand() function and doing mod with 7 with the random number to get the index between 0 to 6, as ut array size is 7(0 to 6).
In the setElement(int index,string color) method we are inserting the value of colors in the colors array based on index.
In the printAllColors() function we are printing all the colors in the array.
In the printRandomColor() er are printing any random color based on rand() function.
and in main() we are initializing the string array with colors and calling the functions.
