Hello there, I just read the file line by line but this line
(All interior angles.... ) doesn't print out separately. it is
USING C++.. The output must
print it separately. I hope it is clear to you. you can
compile my code below and edit it inside my code
please.
Here is my code.
int main(){
string filename;
cout << "Enter the main file ";
cin >> filename;
string category , description, d1 ,d2, d3 ,d4,d5;
int test, cate, num1 , num2, i=1, j=1, num3,num4,
num5,num6;

ifstream fname(filename);
fname >> test;
fname >> cate;
fname >> category >> num1 >>
num2;
cout << category << num1 << num2
<< endl;
while(j <= num1)
{
fname >> d1;
cout << d1 << endl;
j++;
}
cout << endl;

fname >> d2 >> num3 >> num4;

cout << d2 << endl;

while(i <= num3){
fname >> d3;
cout << d3 <<
endl;
i++;
}

//this only two lines need to print
out "All interior angles of a convex polygon are less than
90 degrees
// Their sum product and difference is not the remainder ".
// the code below doesn't work to print out that only two
lines ("All interior angles...")
while(getline(fname,description,' ')){
istringstream
iss(description);
while(getline(iss,d4,' ')
cout << d4
<< endl;
}

fname.close();
}
Here is the input file
