Example:
Input rows: 5
Input columns: 5
Output:
11011 11011 00000 11011 11011
Required knowledge
Basic C programming, LoopLogic to print box number pattern with plus in center
Before we move on to this number pattern basic knowledge of printing box number pattern is recommended.After you are done with the basic box number pattern you can easily get the logic of this pattern. If you look to the pattern carefully, you will notice that the central plus only gets printed if the current column or row is central column, row. Hence before printing 1 inside the inner loop we have to check a condition that if the current row, column is central row, column if so then print 0 instead of 1.
Program to print box number pattern with plus in center
/**
* C program to print box number pattern with plus in center
*/
#include <stdio.h>
int main()
{
int rows, cols, i, j;
int centerRow, centerCol;
/*
* Reads number of rows, columns to be printed
*/
printf("Enter number of rows: ");
scanf("%d", &rows);
printf("Enter number of columns: ");
scanf("%d", &cols);
centerRow = (rows+1)/2;
centerCol = (cols+1)/2;
for(i=1; i<=rows; i++)
{
for(j=1; j<=cols; j++)
{
//Print 0 for central rows or columns
if(centerCol == j || centerRow == i)
{
printf("0");
}
else if((cols%2 == 0 && centerCol+1 == j) || (rows%2 == 0 && centerRow+1 == i))
{
//Print an extra 0 for even rows or columns
printf("0");
}
else
{
printf("1");
}
}
printf("\n");
}
return 0;
}
Output
Enter number of rows: 5
Enter number of columns: 5
Enter number of columns: 5
11011 11011 00000 11011 11011
