Question

Write a program that prompts the user to enter the number of students and each student's name and score, and finally displays the student with the highest score (display the student's name and score). Also calculate the average score and indicate by how much the highest score differs from the average. Use a while loop.

Answer 1

Answer:

Follows are the code to this question:

#include <iostream>//defining header file

using namespace std;

int main()//defining main method

{

int n,s=0,j,number,h=-1;//defining integer variables

string name, nh;//defining string variable

float avg;//defining float variable

cout<<"Enter the number of students: ";//print message

cin>>n;//input value in n

while (j< n) //defining loop for input value

{

getline(cin, name);//use getline method to input value

cout<<"Enter the student name: ";//print message

getline(cin, name);//use getline method to input value

cout<<"Enter the score: ";//print message

cin>>number;//input number value

s+= number;//add numbers into s variable

if(h<number)//defining if block that checks h is greater then number

{

nh= name;//use string variable nh to store name value

h= number;//use integer variable h to store name value

}

j++;//increment j value by 1

}

cout<<name<<endl;//print highest name value

cout<<"score: "<<h<<endl;//print highest score value

avg = (float)s/(float)n;//calculate the average value

cout<<"Average is: "<<avg<<endl;//print average value

cout<<"Difference: "<<(h-avg)<<endl;//print average difference

return 0;

}

Output:

Explanation:

In the above code, inside the main method four integer variable "n,s,j, number, and h", two string variable "name and nh" and one float variable "avg" is defined.

In the next step, n is defined that is used for the input value. and Inside the main method, a while loop is defined, which uses the "getline" method to the input value, and use s variable to add all numbers.

In the next step, if a block is defined that checks "h" is greater than the number value if the condition is true, it will print the highest value of the input variable and its average difference.
