Write a program of Adding a list of number in C++

Add a list of integer from keyboard

Source Code:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

#include <iostream.h> #include <conio.h> using namespace std; int main () { int x; int sum = 0; cout << " Enter your number: <EOF> to stop \n"; while (cin >> x) sum += x; cout << "\n The total number: " << sum << endl; getch (); return 0; } // main

Result:

 Enter your number: <EOP> to stop
15
22
3^d
 The total is: 40

Write a program of A while loop to print number in C++

Simple while loop that prints numbers 10 per line

Source Code:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27

#include <iostream.h> #include <conio.h> #include <iomanip.h> int main () { cout << " Enter an integer between 1 and 100: "; int num; cin >> num; // Test number if (num > 100) num = 100; int lineCount = 0; while (num > 0) { if (lineCount < 10) lineCount++; else { cout << endl; lineCount = 1; }// else cout << setw(4) << num--; } //while getch (); return 0; } // main

Result:

 Enter an integer between 1 and 100:  15
  15  14  13  12  11  10   9   8   7   6
   5   4   3   2   1 

Write a program of Process-control system example in C++

1 2 3 4 5 6 7 8 9 10 11 12 13

while (1) { temp = getTemperture(); if (temp < 68) turnOnHeater(); else if (temp > 78) turnOnAirCond(); else { turnOfHeater(); turnOfAirCond(); } // main } // while(1)

Write a program that convert score to grade in C++

This program reads a test score .Calculate the letter grade based on the absolute scale, and print it

Source Code:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38

#include <iostream.h> #include <conio.h> char scoreToGrade (int score); int main () { cout << " Enter the test score(0-100): "; int score; cin >> score ; char grade = scoreToGrade (score); cout << " The grade is: " << grade << endl; getch(); return 0; } //main /* ============= scoreToGrade =================== This function calculates the letter grade for a score Pre the parameter score Post Return the grade */ char scoreToGrade (int score) { char grade; if (score >= 90) grade = 'A'; else if (score >=80) grade = 'B'; else if (score >=70) grade = 'C'; else if (score >=60) grade = 'D'; else grade = 'F'; getch (); return grade; }// scoreToGrade

Result:

 Enter the test score (0-100): 91
 The grade is: A

Write a Program of Student Grading in C++

This program reads a test score, calculates the letter grade for the score, print the grade

Source Code:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41

#include <iostream.h> #include <conio.h> char scoreToGrade (int score); int main () { cout << " Enter the test score (0-100): "; int score; cin >> score; char grade = scoreToGrade (score); cout << " The grade is: " << grade << endl; getch(); return 0; } //main /* ============= scoreToGrade =================== This function calculates the letter grade for a score Pre the parameter score Post Return the grade */ char scoreToGrade (int score) { int temp = score / 10; char grade; switch (temp) { case 10 : case 9 : grade = 'A'; break; case 8 : grade = 'B'; break; case 7 : grade = 'C'; break; case 6 : grade = 'D'; break; default : grade = 'f'; break; }// switch getch(); return grade; }// scoreToGrade

Result:

 Enter the test score (0-100): 89
 The grade is: B
