Answer:

The correct answer is Adaptive differential pulse code modulation

Explanation:

Adaptive differential pulse code modulation (ADPCM) is a variant of differential pulse-code modulation (DPCM) that varies the size of the quantization step, to allow further reduction of the required data bandwidth for a given signal-to-noise ratio. The output data rate can be dynamically adjusted between 16 kbit/s and 64 kbit/s in these applications.

satela [25.4K]

In this program, I am using the school-based grading system and the program should accept the subject and the number of students.

Program approach:-

Using the necessary header file.
Using the standard I/O namespace function.
Define the main function.
Declare the variable.
Display enter obtain marks in 5 subjects.
Return the value.

Program:-

//header file

#include<iostream>

//using namespace

using namespace std;

//main method

int main()

{

//declare variable

int j;

float mark, sum=0, a;

//display enter obtain marks in 5 subjects

cout<<"Enter Marks obtained in 5 Subjects: ";

for(j=0; j<5; j++)

{

cin>>mark;

sum = sum+mark;

}

a = sum/5;

//display grade

cout<<"\nGrade = ";

if(a>=91 && a<=100)

//display a1

cout<<"a1";

else if(a>=81 && a<91)

//display a2

cout<<"a2";

else if(a>=71 && a<81)

cout<<"b1";

else if(a>=61 && a<71)

cout<<"b2";

else if(a>=51 && a<61)

//display c1

cout<<"c1";

else if(a>=41 && a<51)

//display c2

cout<<"c2";

else if(a>=33 && a<41)

//display d

cout<<"d";

else if(a>=21 && a<33)

//display e1

cout<<"e1";

else if(a>=0 && a<21)

//display e2

cout<<"e2";

else

//display invalid

cout<<"Invalid!";

cout<<endl;

//return the value

return 0;
