Number Patterns in C

In C programming, a "number pattern" typically refers to the practice of arranging numbers in a structured format using nested loops. These patterns can be simple or complex, depending on the logic applied.

#include <stdio.h>
 main() {
    int i, j;
    for (i = 1; i <= 5; i++) 
	{       
        for (j = 1; j <= i; j++) 
		{   
            printf("%d", j);         
        }
        printf("\n");                
    }
    return 0;
}

• Outer Loop (i) : Runs from 1 to 5, representing each row.
• Inner Loop (j) : Runs from 1 to the current value of i, representing the numbers in each row.
• Print Statement : Prints the current value of j.
• New Line : After the inner loop completes, a new line is printed to move to the next row.

#include <stdio.h>
main() {
    int i, j;
    for (i = 5; i >= 1; i--) {       
        for (j = 1; j <= i; j++) {   
            printf("%d", j);         
        }
        printf("\n");                
    }
}

#include <stdio.h>
main() {
    int i, j, k, n = 5;
    for (i = 1; i <= n; i++) {
        for (j = i; j < n; j++) {
            printf(" "); 
        }
        for (k = 1; k < i; k++) {
            printf("%d", k); 
        }
        for (k = i; k >= 1; k--) {
            printf("%d", k); 
        }
        printf("\n");
    }
}

#include<stdio.h>
main()
{
	int i,j;
	for(i=5;i>=1;i--)
	{
		for(j=i;j>=1;j--)
		{
			printf("%d",j);
		}
		printf("\n");
	}
}

#include<stdio.h>
main()
{
	int i,j;
	for(j=5;j>=1;j--)
	{
		for(i=j;i<=5;i++)
		{
			printf("%d",i);
		}
		printf("\n");
	}
}

• Loops : for, while, or do-while loops are used to repeat code.
• Nested Loops : Using loops inside other loops to create complex patterns.
• Conditional Statements : Sometimes if-else statements are used for more intricate patterns.
• Print Formatting : Proper use of printf for aligning and formatting output.

Number patterns in C are a great way to practice and understand loops and nested loops. They help in developing logic building and understanding the control flow in programs. Once you get comfortable with basic patterns, you can experiment with more complex ones.
