C program to Print Number Pattern 1

In this article we will show you, How to write a C program to Print Number Pattern 1 with example. Or, C Program to Print Rectangle Number Pattern.

C program to Print Number Pattern 1 using For Loop

This program allows the user to enter the maximum number of rows and columns he/she want to print as a rectangle. Next, compiler will print the numbers from 1 to user specified rows.

/* C program to Print Number Pattern 1 */

#include<stdio.h>

int main()

{

int i, j, rows, columns;

printf(" \nPlease Enter the Number of Rows : ");

scanf("%d", &rows);

printf(" \nPlease Enter the Number of Columns : ");

scanf("%d", &columns);

for(i = 1; i <= rows; i++)

{

for(j = 1; j <= columns; j++)

{

printf("%d", i);

}

printf("\n");

}

return 0;

}

OUTPUT

ANALYSIS

Let us see the Nested for loop

for(i = 1; i <= rows; i++)

{

for(j = 1; j <= columns; j++)

{

printf("%d", i);

}

printf("\n");

}

Outer Loop – First Iteration

From the above screenshot you can observe that, The value of i is 7 and the condition (i <= 7) is True. So, it will enter into second for loop

Inner Loop – First Iteration

The j value is 1 and the condition (1 <= 9) is True. So, it will start executing the statements inside the loop.

1	printf(" %d", i);

Following statement will be incremented by 1 using the Increment Operator

j++

This will happen until the condition inside the inner for loop fails. Next, iteration will start from beginning until both the Inner Loop and Outer loop conditions fails.
