## PREREQUISITE:

Basic knowledge of C language and loops.

## ALGORITHM:

1. Take number of rows as input from the user and save it in any variable (‘r’in this case).
2. Run a loop ‘r’ number of times to iterate through the rows. From i=0 to i<r.  The loop should be structured as for( i=0 ; i<r ; i++).
3. Inside this if condition use an id condition to print the top and bottom rows. if(i==0 || i==r-1).
4. Inside this run a nested loop to iterate through the columns. From  j=0 to j<3. The loop should be structured as for(j=0 ; j<3 ; j++).
5. Print “3” in this loop.
6. Write an else condition. Inside it a run a similar loop . From  j=0 to j<3. The loop should be structured as for(j=0 ; j<3 ; j++).
7. Use an if condition. if(j==0 || j==2). And  print “3”.
8. Else print the iterating variable for rows.
9. Inside the main loop print a newline

## CODE IN C:

```#include<stdio.h>
int main()
{
int i,j,r;                                          //declaring integer variables i,j for loops , r for number of rows
printf("Enter the number of rows :\n");             //asking user for input
scanf("%d",&r);                                     //saving number of rows in variable r
for(i=0;i<r;i++)                                    //loop for number of rows
{
if(i==0 || i==r-1)                            //if condition to print first and last row
{
for(j=0;j<3;j++)                        //loop to print first and last row
{
printf("3");                      //printing 3
}
}
else                                          //else to print rest of the square
{
for(j=0;j<3;j++)                        //loop to print the rest of the square
{
if(j==0 || j==2)                  //if condition to print the outer values
{
printf("3");                //printing 3
}
else//else condition to
{
printf("%d",i);              //Printing the middle column
}
}
}
printf("\n");                                  //printing newline
}
}```
