Give a number

//Strong number

//Strong numbers are the numbers whose sum of factorial of digits is equal to the number. For Example: 145 is a strong number

//Since 1! + 4! + 5! = 145

// 1,2,145 and 40585 are examples of strong numbers

while ($number != 0)

for ($i = 1; $i <= $number % 10; $i++)

$fact *= $i;

$sum += $fact;

$number = (int)($number / 10);

A simple program that I wrote in PHP that will ask the user to give the year and month and then our program will give how many days in the given month and year to the user. The code is very simple and easy to understand.

Grade Evaluator in C++

Here is another example of my work in C++ to compute and evaluate the grades of the student whether the student, pass or failed in the subject. The code using two dimensional array as its data structure and looping statements. I hope you will find my work useful in learning C++ programming.

Add me at Facebook my address is jakerpomperada@gmail.com and jakerpomperada@yahoo.com.

My mobile number here in the Philippines is 09173084360.

Program Listing

#include <iostream>

#include <iomanip>

using namespace std;

main() {

int grades[5][1],pass=0,failed=0,out_range=0;

int row=0, col=0;

string remarks;

char letter_grade;

cout << "\t Grades Evaluator Version 1.0";

cout << "\n\n Created By: Mr. Jake Rodriguez Pomperada,MAED-IT";

cout << "\n\n";

for ( row=0; row < 5; row++) {

for (col=0; col < 1; col++) {

cout << "Enter grade : " ;

cin >> grades[row][col];

}

// Code to check for remarks

cout <<"\n" << setw(5) << "GRADES" <<

setw(7) << " EQUIV " <<

setw(10) << "REMARKS";

cout << "\n\n";

for ( row=0; row < 5; row++) {

for (col=0; col < 1; col++) {

if (grades[row][col] >= 75) {

remarks = "PASSED";

pass++;

}

else if (grades[row][col] < 50)

{

remarks= " Error Out of Range ";

out_range++;

}

else if (grades[row][col] < 75){

remarks = "FAILED";

failed++;

}

// Letter Grade Equivalent

if (grades[row][col] >= 90 && grades[row][col] <= 100 ) {

Simple Grade Solver in C++

A simple grade solver that will solve the prelim, midterm and final grade of the student using C++ as my programming language. I used this sample program in my programming class before in college as an example prior I worked here in the IT industry. I hope you will find my work useful and interesting.

Add me at Facebook my address is jakerpomperada@gmail.com and jakerpomperada@yahoo.com.

Program Listing

#include <iostream>

using namespace std;

main()
{
string grading[3] = {"Prelim","Midterm","Endterm"};
int grade[3][1];
int add=0, solve=0;
bool remarks;
cout << "Simple Grade Solver 1.0";
cout << "\n\n";
for (int a=0; a<3; a++) {
for (int b=0; b<1; b++)
{

cout << "Enter " <<grading[a]
<< " grade : ";
cin >> grade[a][b];
add+=grade[a][b];
}
solve= add/3;
}
cout << "You grade is " << solve;
cout << "\n\n";
if (solve >= 75)
{
remarks = true;
}
else {
remarks = false;

}

switch (remarks) {

case 1 : cout << "You Pass";
break;
default : cout << "You Failed";
}
cout << "\n\n";
system("pause");
}

Grade Brackets in C++

In this article I would like to share with you a sample program that I wrote for my class in C++ programming 6 years ago to check and determine the grade brackets of the students using two dimensional array in C++. The code is very simple and easy to understand I hope you will find my work useful in learning C++ programming.

Add me at Facebook my address is jakerpomperada@gmail.com and jakerpomperada@yahoo.com.

Program Listing

#include <iostream>

using namespace std;

main()

{

double grades[5][2];

int row=0,col=0, count=0, count2=0;

int count3=0, count4=0;

cout << "\t Grade Bracket Version 1.0 ";

cout << "\n\n";

// Ask for 10 grades

for(row= 0 ; row < 5 ; row++){

for (col=0; col <2; col++) {

cout<< "Enter grades :=>";

cin >> grades[row][col];

}

for(row= 0 ; row < 5 ; row++){

for (col=0; col <2; col++) {

if(grades[row][col] >= 90){

count++;

}

if(grades[row][col] >= 80 && grades[row][col] <90)

{

count2++;

}

if(grades[row][col] >= 75 && grades[row][col] < 80)

{

count3++;

}

if(grades[row][col] < 75)

{

count4++;

}

//display

cout << "\n====================";

cout << "\n RESULTS ";

cout << "\n====================";

cout << "\n\n";

cout<<"\nGrades >=90 is: " <<count;

cout<<"\nGrades 80 - 89 is: " <<count2;

cout<<"\nGrades 75 - 80 is: " <<count3;

cout<<"\nGrades < 75 is: " <<count4;

cout << "\n\n";

system("pause");
