Write a C++ program to accept percentage and print division accordingly.

Q22. Write a C++ program to accept percentage and print division accordingly.

Solution:

#include<iostream.h> //standard input/output header file

#include<conio.h> //for clrscr()

 

int main()

{

int per;

 

clrscr(); //for clearing the screen

 

cout<<“\n Enter the percentage: “;

cin>>per;

 

per>=60? cout<<“\n I Division.” : per<60&&per>=45? cout<<“\n II Division.” :per>=36? cout<<“\n III Division.” : cout<<“\n Fail.”;

 

getch(); //holds the screen until any key is pressed

return 0; //makes main() finish

}

 

OUTPUT:

CASE 1:

Enter the percentage: 78

 

I Division.

 

CASE 2:

Enter the percentage: 57

 

II Division.

 

CASE 3:

Enter the percentage: 33

 

Write a C++ program to take input in three subjects Physics, Chemistry and Math’s and calculate the total and percentage.

Q15. Write a C++ program to take input in three subjects Physics, Chemistry and Math’s and calculate the total and percentage.

Solution:

#include<iostream.h> //standard input/output header file

#include<conio.h> //for clrscr()

 

int main()

{

int Phy,Chem,Maths,total,per;

 

clrscr(); //for clearing the screen

 

cout<<“\n Enter the marks of Physics: “;

cin>>Phy;

cout<<“\n Enter the marks of Chemistry: “;

cin>>Chem;

cout<<“\n Enter the marks of Math’s: “;

cin>>Maths;

 

total=Phy+Chem+Maths;

per=total/3;

 

cout<<“\n Total= “<<total;

cout<<“\n Percentage= “<<per<<“%”;

 

getch(); //holds the screen until any key is pressed

return 0; //makes main() finish

}

 

OUTPUT:

Enter the marks of Physics: 78

Enter the marks of Chemistry: 89

Enter the marks of Math’s: 90

Total= 257

Percentage= 85%
