a program for transposing a matrix but in this program in printing result it has a bug, for example, this program for a Square matrix print first matrix
You've interchanged the row and column indices. Printing b[i][j]
works fine. Even with non square matrices.
printf("transposed matrix:\n");
for(i=0;i<m;i++)
{
for(j=0;j<n;j++)
{
printf("%d ",b[i][j]);
}
printf("\n\n");
}
Here is an example:
a[1][1]= 1
a[1][2]= 2
a[2][1]= 3
a[2][2]= 4
a[3][1]= 5
a[3][2]= 6
first matrix:
1 2
3 4
5 6
transposed matrix:
1 3 5
2 4 6
