Answer 1

There are multiple ways to do this. Here are two ways:

1)

ifstream inFile;
int array[100];
index = 0;

inFile.open("file.txt");

while(index < 100 && inFile >> array[index])
{
index++;
}


2)

ifstream inFile;
int array[100];
index = 0;

inFile.open("file.txt");

while(index < 100 && !inFile.eof())
{
inFile >> array[index];
index++;
}

// I hope this helps

Answer 2

FILE fp;


while(index<100 && feof(fp))

Answer 3
