Edit the following code to read the input for 10 students from a file testData1.txt and output the average of scores for 10 students using a loop. #include using namespace std; #include int main(){ string name1,name2,name3; double score1,score2,score3; char c1,c2,c3; double avg; ifstream inputFile; ofstream outputFile; inputFile.open("testData1.txt"); outputFile.open("Results.txt"); inputFile.clear(); inputFile>>name1>>score1>>c1; inputFile.clear(); inputFile.ignore(200,'\n'); inputFile>>name2>>score2>>c2; inputFile.clear(); inputFile.ignore(200,'\n'); inputFile>>name3>>score3>>c3; avg =(score1 + score2 +score3)/3.0; outputFile << endl<
Types of Loop
Loops are the elements of programming in which a part of code is repeated a particular number of times. Loop executes the series of statements many times till the conditional statement becomes false.
Loops
Any task which is repeated more than one time is called a loop. Basically, loops can be divided into three types as while, do-while and for loop. There are so many programming languages like C, C++, JAVA, PYTHON, and many more where looping statements can be used for repetitive execution.
While Loop
Loop is a feature in the programming language. It helps us to execute a set of instructions regularly. The block of code executes until some conditions provided within that Loop are true.

Edit the following code to read the input for 10 students from a file testData1.txt and output the average of scores for 10 students using a loop.
#include <fstream>
using namespace std;
#include <iomanip>
int main(){
string name1,name2,name3;
double score1,score2,score3;
char c1,c2,c3;
double avg;
ifstream inputFile;
ofstream outputFile;
inputFile.open("testData1.txt");
outputFile.open("Results.txt");
inputFile.clear();
inputFile>>name1>>score1>>c1;
inputFile.clear();
inputFile.ignore(200,'\n');
inputFile>>name2>>score2>>c2;
inputFile.clear();
inputFile.ignore(200,'\n');
inputFile>>name3>>score3>>c3;
avg =(score1 + score2 +score3)/3.0;
outputFile << endl<<setw(20)<<left<<"Name" <<setw(20)<<"Score"<<setw(20)<<left<<"School Year";
outputFile << endl<<setw(20)<<left<<"----" <<setw(20)<<"-----"<<setw(20)<<left<<"-----------";
outputFile << endl<<setw(20)<<left<<name1 <<setw(20)<<score1<<setw(20)<<left<<c1;

outputFile << endl<<setw(20)<<left<<name3 <<setw(20)<<score3<<setw(20)<<left<<c3;
outputFile << "\n\nAverage score is "<<fixed<<showpoint<<setprecision(2)<<avg<<endl;
inputFile.close();
outputFile.close();
}
