[@prasadparanjape6234]

Code isnt showing output even if n is changed by row

[@nishantnirala1847]

Can you explain
for getmarkedcol( ) what does the function return if a[row][i]=='Q' case is not encountered ?

[@ram3616]

it returns cell position i mean column index position.

[@shubhamgarde6830]

[@nitinsrivastava]

Hi can you explain what is the return value if it not returning anything and the if the (if condition is getting wrong for first time)??
int getmarkedcol(int row) {
int i;
for (i = 0; i < n; i++)
{
if (a[row][i] == 'Q')
{
return (i);
break;
}
}
}
