السلام عليكــم ورحمـة الله وبركاتــه ،،
I am trying to make a program that transforms a normal matrix into the r.r.e.f. form (linear algebra).
The problem is that when running the program it only does the first if rule
:huh: .
I should say that im only a beginner and im trying to learn from this.
P.S. : the code is written in dev-cpp .
/* Info. : A program for converting any matrix into an r.r.e.f. form
*/
/*----------------------------------------------------------------------------*/
#include<iostream>
using namespace std;
int main()
{
int r ,c ,i ,j ;
cout<<"Enter the number of rows : "; //reading data (input)
cin>>r;
cout<<"Enter the number of columns : ";
cin>>c;
cout<<endl<<endl;
float row[r][c] ,col[c][r], temp ;
for(i=0 ; i<r ; i++ )
{
cout<<"Enter the elements of the ( "<<i+1<<" ) row : ";
for(i=i , j=0 ; j<c ; j++ )
{
cin>>row
[j];
}
}
cout<<endl<<endl;
if ( row[0][0]>0 ) //r.r.e.f.
{
temp=row[0][0] ;
for(j=0 ; j<c ; j++)
{
row[0][j]=row[0][j]/temp ;
}
}
else if ( row[0][0]<0 ) //here is the problem!
{
temp=row[0][0]*-1 ;
for(j=0 ; j<c ; j++)
{
row[0][j]=row[0][j]/temp ;
}
}
/*----------------------------------------------------------------------------*/
for(i=0 ; i<r ; i++ ) //checking data (output)
{
cout<<"The elements of the ( "<<i+1<<" ) row : ";
for(i=i , j=0 ; j<c ; j++)
{
cout<<row
[j]<<" ";
}
cout<<endl;
}
cout<<endl<<endl;
system("pause");
return 0;
}
