Write a program that reads a file consisting of students test scores in the range 0-200, it should then determine the number of students having scores in each of the following ranges: 0-24, 25-49, 50-74, 75-99, 100-124, 125-149, 150-174, 175-200. Output the score ranges and the number of students. (Run your program with the following input data : 76, 89, 150, 135, 200, 76, 12, 100, 150, 28, 178, 189, 167, 200, 175, 150, 87, 99, 129, 149, 176, 200, 87, 35, 157, 189.

And here is my answer

#include <fstream>

#include <string>

using namespace std;

void initialize(int student[]);

void getStudent(int category, int student[]);

void printArray(int category, int student[]);

int main()

ifstream infile;

infile.open("testscore.txt");

if (!infile)

{

cout<<"Cannot open input file. "<< endl;

return 1;

}

initialize(student);

infile>>score;

while (!infile.eof())

{

category = getCategory(score);

getStudent(category, student);

}

infile.close();

printArray(category, student);

system("Pause");

return 0;

}

Write a program that reads in ten whole numbers and that output the sum of all the numbers greater than zero, the sum of all the numbers less than zero (which will be a negative number or zero), and the sum of all the numbers, whether positive, negative, or zero. The user enters the ten numbers just once each and the user can enter them in any order. Your program should not ask the user to enter the positive numbers and the negative numbers separately.

Assume the user will type integer numbers.

this is what i got but it wont run saying there is an error

#include<iostream>;

using namespace std;

int main()

{

int count=0;

int num;

int positive=0;

int negative=0;

do

{

cout<<"Enter 10 whole numbers"<<endl;

cout<<num;

if (num<=0)

{

negative= negative+num;

}

else

{

positive= positive+num;

}

count++;

}

while (count<10);

cout<<" Sum of postive number= "<< positive<<endl;

cout<<" Sum of negative number= "<<negative<<endl;

cout<<" Sum of all numbers= " <<positive+ negative<<endl;

}

plz show details

Please explain in detail plz

Write a program to calculate students’ average test scores and their grades.

You may assume the following input data:

Johnson 85 83 77 91 76

Aniston 80 90 95 93 48

Cooper 78 81 11 90 73

Gupta 92 83 30 69 87

Blair 23 45 96 38 59

Clark 60 85 45 39 67

Kennedy 77 31 52 74 83

Bronson 93 94 89 77 97

Sunny 79 85 28 93 82

Smith 85 72 49 75 63

Use three arrays: a one-dimensional array to store the students’ names, a (parallel) two-dimensional array to store the test scores, and a parallel one dimensional array to store grades. Your program must contain at least the following functions: a function to read and store data into two arrays, a function to calculate the average test score and grade, and a function to output the results. Have your program also output the class average.

#include<iostream>

#include<cctype>

#include<string>

using namespace std;

const int numrows=10;

const int numcol=5;

int matrix [numrows][numcol];

void sumrows(int matrix[][numcol],int numrow);

int main()

{

const int Max=10;

string Name[Max]= {"Johnson","Aniston","Cooper","Gupta","Blair","Clark","Kennedy","Bronson","Sunny","Smith"};

for (int i=0; i < Max; i++)

//cout<<Name[i] <<endl; displays names

const int Rows=10;

const int Col=5;

int studentGrades[numrows][numcol]= {{85, 83, 77, 91, 76},

{80, 90, 95, 93, 48},

{78, 81, 11, 90, 73},

{23, 45, 96, 38, 59},

{60, 85, 45, 39, 67},

{77, 31, 52, 74, 83},

{93, 94, 89, 77, 97},

{79, 85, 28, 93, 82},

{85, 72, 49, 75, 63}};

sumrows(studentGrades, numrows);

cout<<endl;

return 0;

}

void sumRows(int matrix[][numcol],int numrows)

{

int row, col;

int sum;

for(row=0; row < numrows; row ++)

{

sum=0;

for(col =0; col < numcol; col++)

sum=sum+matrix[row][col];

cout<<"average =" <<(row+1)<<sum<<endl;

Three employees in a company are up for a special pay increase. You are

given a file, sayCh3_Ex7Data.txt, with the following data:

Miller Andrew 65789.87 5

Green Sheila 75892.56 6

Sethi Amit 74900.50 6.1

Each input line consists of an employee’s last name, first name, current salary,

and percent pay increase. For example, in the first input line, the last name of

the employee is Miller,thefirstnameisAndrew, the current salary is

65789.87, and the pay increase is 5%. Write a program that reads data from

the specified file and stores the output in the file Ch3_Ex7Output.dat.

For each employee, the data must be output in the following form:

firstName lastName updatedSalary. Format the output of decimal

numbers to two decimal places
