C programs to display Pattern according to number of rows (2)

In these C programs (Page 2), we are going to learn how to print display patterns using numbers where number of rows is given?

Example 1: When number of rows: 4

       4
      345
     23456
    1234567

Example 2: When number of rows: 5

        5
       456
      34567
     2345678
    123456789

Here is the C program, that will read number of rows from user and print the display pattern of numbers according to given input.

#include <stdio.h>

int main()
{
	int num_of_rows,i,j;

	printf("Enter Number Of Rows: ");
	scanf("%d",&num_of_rows);

	for(i=1;i<=num_of_rows;++i)
	{
		for(j=1;j<=(2*num_of_rows-1);++j)
		{
			if(j>=(num_of_rows+1-i) && j<=(num_of_rows-1+i))
				printf("%d",j);
			else
				printf(" ");
		}

		printf("\n");
		j=1;
	}

	return 0;
}
