Answer 1

You can not have multiple inputs, that is just SoloLearn thing you have to get used to. So you can get only one input. Note: i have noticed that u use i<=3 in for loops, but your 2d array is [3][3]. Arrays start form zero, so in your case you will loop through 4 rows and 4 columns . Just delete the assignment operator and you will be fine :)

Answer 2

Miss RoShAni Sharma
canio.h is deprecated header file will not work. So remove that.
instead of getch use getchar();
Remove or comment clrscr() ;
Make void main() to int main().
a[3][3] contains 3*3 =9 elements.
Index starts from 0.
so maximum index is a[2][2]. If you access beyond that you get garbage values..
So loop should be like
for(i=0;i<3;i++) //not <=3

Inputs give like
2 3 4 5 2 2 2 2 2 2 1 2 2 2 2 2 2 2

All required inputs at one time only...
