C program to Print Number Pattern 4

Write a C program to Print Number Pattern 4 with example. For this, we are going to use For Loop and While Loop.

C program to Print Number Pattern 4 using For Loop

This program allows the user to enter the maximum number of rows he/she want to print as a right triangle. Next, compiler will print the required numbers pattern.

/* C program to Print Number Pattern 4 */

#include<stdio.h>
 
int main()
{
    int i, j, rows;
	     
    printf(" \nPlease Enter the Number of Rows : ");
    scanf("%d", &rows);
         
    for(i = 1; i <= rows; i++)
    {
    	for(j = 1; j <= i; j++)
		{
			printf("%d", j);     	
        }
        printf("\n");
    }
    return 0;
}
C program to Print Number Pattern 4 1

Let us see the Nested for loop

for(i = 1; i <= rows; i++)
{
	for(j = 1; j <= i; j++)
	{
		printf("%d", j);     	
        }
        printf("\n");
}

Outer Loop – First Iteration

From the above screenshot you can observe that, The value of i is 5 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 <= 1) is True. So, it will start executing the statements inside the loop.

printf("%d", j);

Next, we used the Increment Operator j++ to increment the J value by 1. This will happen until the C Programming condition inside the inner for loop fails. Next, iteration will start from beginning until both the Inner Loop and Outer loop conditions fails.

Program to Print Number Pattern 4 using while Loop

In this program we just replaced the For Loop with the While Loop. I suggest you to refer While Loop article to understand the logic.

/* C program to Print Number Pattern 4 */

#include<stdio.h>
 
int main()
{
    int i, j, rows;
    i = 1;
	     
    printf(" \nPlease Enter the Number of Rows : ");
    scanf("%d", &rows);
         
    while(i <= rows)
    {
    	j = 1;
    	
    	while( j <= i)
		{
			printf("%d", j);    
			j++; 	
        }
        i++;
        printf("\n");
    }
    return 0;
}
