Input text file as an array? For example if the text file contained something like
//names and grades
Bob 98 92 66 90
Sara 88 75 39 85
Joe 92 99 99 12
Would it be correct to do
#include <iostream>
#include <fstream>
#include <string>
using namespace std;
void main()
{
string studentname[3], grade1[3], grade2[3], grade3[3];
ifstream input;
input.open("grades.txt");
while(!input.eof())
(
for(int i=0; i<3; i++)
input>>studentname[i]>>grade1[i]>>grade2[i]>>grade3[i];
}
input.close()
}
The code you posted requires the program to read just 3 lines of text. What happens if there is only 1 line, or 20 lines, or 1,000 lines? You certainly don't want to have to count the number of lines before reading the file.
A solution is to
1. Create a structure to hold all the information for one person
2. Use a vector of the structors so that the vector can hold as much or as little data as there is in the file.
3. read the file until end-of-file is reached.
