Hello, I got some errors from void and others. Is something wrong that?

#include <cstdlib>
#include <iostream>
#include <string>
using namespace std;

int main()
{
const int size=5;
//array for students’ names
string sNames[size];
//get Names
for(int i=0; i<5; i++)
{
cout << "Enter a student’s name: ";
cin >> sNames[i];
}

//get scores
double scoreForS[size][4], avg[size],sum[size]={0,0,0,0,0};

for(int x=0;x<5;x++)
{
for(int y=0;y<4;y++)
{
cout<< "Enter the score for student " <<(x+1)<< " ";
cin>>scoreForS[x][y];
//input validation
while(scoreForS[x][y]<0||scoreForS[x][y]>100)
{
cout << "Error.The range of score is 0 to 100. Reenter : ";
cin >> scoreForS[x][y];
}
sum[x] += scoreForS[x][y];
}
}

//drop lowest score

double lowest[size];

for(int a=0;a<5;a++)
{
lowest[a]= scoreForS[a][0];
for(int b=1;b<4;b++)
{
if (lowest[a]>scoreForS[a][b])
lowest[a]= scoreForS[a][b];

}
sum[a]-=lowest[a];
}

//get avg
for(int c=0;c<5;c++)
{
avg[c]=sum[c]/3.0;
}

//scale
char grade[size];
for(int d=0;d<5;d++)
{
if(avg[d]>=90)grade[d]='A';
else if(avg[d]>=80)grade[d]='B';
else if(avg[d]>=70)grade[d]='C';
else if(avg[d]>=60) grade[d]='D';
else grade[d]='F';
cout<<"\nStudent " << sNames[d] << " get " << grade[d];
}

system("pause");
return 0;
}

void calcdata(int NUM_NAMES, double testscore[][NUM_TESTS])
{
     
double total;


for (int row = 0; row < NUM_NAMES; row++)
{

	total = 0;

	for (int col = 0; col < NUM_TESTS; col++)
	
		total += testscore[row][col];

		average[row] = total / NUM_TESTS;
	

		if (average[row] < 60)
			grade[row] = 'F';
		else if (average[row] < 70)
			grade[row] = 'D';
		else if (average[row] < 80)
			grade[row] = 'C';
		else if (average[row] < 90)
			grade[row] = 'B';
		else if (average[row] < 100)
			grade[row] = 'A';
			
}
for (int i = 0; i < 5; i++)
cout << "Student: " << name[i] <<" average: " << average[i] <<" grade: " << grade[i] << endl;
}

Anyone do u have idea?

The errors I got with your code were all about undeclared identifiers. They seemed pretty self-explanatory to me.

Hmm...Should I put integer with them on function prototype?

In Visual Studio, just double click on the first error and it will take you to the line of code causing the error (or very close to the offending line of code).

If you don't know what the error means, paste the error in quotes in a bing or google search.

All your compile errors are in the calcdata function which is not currently being used. Comment out this function and the program will compile OK.

Also, you have defined a const int to be the size of the used arrays. However, in the loops that access the arrays you are not using the const int but have the size hardcoded.

I also take it that for each student you enter 4 scores. This number should be defined as a const int and used in the loops. I would also suggest that during the score input stage you state the score number required as well as the student number so the user knows exactly what score they are entering.
