Score Board Project in c++ language in hindi , cricket score sheet mini project in c++ source code

cricket score sheet mini project in c++ source code , Score Board Project in c++ language in hindi :-
इस प्रोजेक्ट मे , किसी class के student के मार्क्स के हिसाब से score board को बनाया जाता है |Explanation
1. सबसे पहले class student को डेफिन किया जाता है | जिसमे दो तरह के member होते है :-
private member :
इस क्लास मे ,
int Rollnumber : ये student के roll number को hold करता है |
char name[50] : ये student के नाम को hold करता है |
PHISICS_MARKS : ये student के physics subject के मार्क्स को hold करता है |
CHEMISTRY_MARKS: ये student के chemistry subject के मार्क्स को hold करता है |
MATHS_MARKS : ये student के math subject के मार्क्स को hold करता है |
ENGLISH_MARKS :ये student के English subject के मार्क्स को hold करता है |
HINDI_MARKS : ये student के Hindi subject के मार्क्स को hold करता है |
double percentage : ये student द्वारा प्राप्त किये गये percentage को hold करता है |


इसके अलावा इस class मे , निन्म public function है जिससे प्रोजेक्ट के मुख्य operation को perform किया जाता है |
calculate() : इस function का use average को calculate करने एक लिए किया जाता है |
getdata() : इस function का use , student से data को input करने एक लिए किया जाता है |
showdata() : इस function का use data को show करने के लिए किया जाता है |
void class_result(): इस function का use file मे से data को read करके screen पर print करने के लोइए use किया जाता है |  
void result() : इस function का use result के menu को print करने के लिए किया जाता है |            


इस प्रोग्राम मे file handling को use किया गया है जिससे हम पहले discuss कर चुके है |
