Closed C++ problem

[Kingrhejj]

Need help about c++ mga ka phc.

ayaw mag stop ng program
Sa expression na
while ( n > 0) ;
Example.) n = -90
90 < 0; ( false )

Given problem:
Write a program written in c++ language to calculate the average of an unknown number of grade .

*Prompts the user to enter a grade each time through the loop.

* update the sum and number of grade.

*prompts the user to enter a negative grade after the last valid grade.

*continue looping while the input grade is not negative.

Kaso ayaw mag stop ng program kahit mag enter ako ng negative grade .



#include<iostream>
using namespace std;
int main () {
int i, n, b, t, sum = 0, num[100];
float ave;
for ( i = 0; ; i ++) {
cout<<i+1<<".Enter a Grade : ";
cin >> num;
t++;
sum += num;
ave = sum /t;
b=ave;
cout << " Sum : " << sum << endl;
cout << " ENTER NEGATIVE GRADE : ";
cin >> num;
}while ( n > 0 );
b=ave;
cout << " Average : " << b<< " % " <<endl;

return 0;
}

huhu

for ( i = 0; ; i ++) para saan to?

 

[Jannelle345]

while ( n > 0 ); at yan bakit ka nag while dyan?

 

[mrHazan]

hindi pwede magsama ang while saka for sa isang block.
For for loop lang.
While while loop lang.

Hahaha kala ko do yung nilagay nya for loop pa tlga okay lng sana do yun

 

[Jannelle345]

At tyka saan mo kukunin yun "n" mo sa while ( n > 0 )

 

[mrHazan]

Hindi kailangang array yung num mo.
Hindi mo na kailangan yung variable b and n mo.
Basta hindi maganda flow ng code mo.

Ang gulo sakit sa Bangs haha

Paki enlighten ako sa part na to
*prompts the user to enter a negative grade after the last valid grade. // MAGLAGAY NG NEGATIVE GRADE PAGKATAPOS NG VALID GRADE? ANO UN ? pano mo masasabing valid grade? Positive?

*continue looping while the input grade is not negative. // ANO RAW? magloloop kapag hindi negative? e sabi sa taas maglagay ng negative grade after valid?

HAHA GULO

 

[Kingrhejj]

Do while loop pa lng kc naituro samin tapos na assignment na nmin yn

Ibig sabihin yata non mag cocontinue ang program sa pag henge ng grade pag false ang hinihinging negative grade

 

[Kingrhejj]

while ( n > 0 ); at yan bakit ka nag while dyan?

Ano ba dapat jn sir?? If else if statement/s?

 

[Kingrhejj]

for ( i = 0; ; i ++) para saan to?

For infinite

While while loop lang.[/QUO
Nasa ibng block na po ung while

 

[Kingrhejj]

Unknown grades po kc,,, pwdeng isa,dalawa or so on,, kaya humihingi ng negative grade para mag stop ang program,,
Kylangan pa kcng gamitan ng break; para mastop ang program

 

[mrHazan]

Ganito lang format ng loop.

while (parameter)
{
code
}

do
{
code
} while(bool)

for(statements)
{
code
}

walang
for(statemetns)
{
code
} while(bool)

gets mo na?

Ito na pag aralan mo, compile mo para makita mo.

#include <iostream>
using namespace std;

// Global Dec
int programEnd = 0 , count = 0;

Func1(){
    // Declarations
    int grade, sum;
    float average;
   
    cout << "Enter a grade: ";
    cin >> grade;
    if (grade < 0){
        programEnd = 1;
    }
   
    // Computation
    sum += grade;
    count += 1;
    average = sum / count;
   
    cout << "Current grade total is: " << sum << endl;
    cout << "Current number of grades: " << count << endl << endl;
    cout << "Current Average is: " << average << endl << endl << endl;
}

main(){
    cout << "The Program will end if you input a NEGATIVE GRADE" << endl << endl;
   
    for(programEnd; programEnd < 1;){
        Func1();
    }       
}

    cout << "Current Average is: " << average << endl << endl << endl;
}

main(){

    for(programEnd; programEnd < 1;){
        Func1();
    }      
}

Gawa mo ba yn boss or copy paste mo lng ?
May error kc. Btw ty

masyadong complicated para sa easy problem.
