Program To Print Pattern 5

Write a program to print the following pattern

Algorithm

STEP 1: START
STEP 2: SET lines=8, i=1,j=1,k=1
STEP 3: REPEAT STEP 4 to 13 UNTIL i is less than lines
STEP 4: SET j=1
STEP 5: REPEAT STEP 6 and 7 UNTIL j is less than or equals to (lines/2)
STEP 6: IF j is equals to i PRINT j
ELSE IF i is greater than 4 and j equals lines-i PRINT j
ELSE PRINT " "
STEP 7: j = j + 1
STEP 8: j = j - 2
STEP 9: REPEAT STEP 10 and 11 UNTIL j is greater than 0
STEP 10: IF j is equals to i PRINT j
ELSE IF i is greater than 4 and j equals lines-i PRINT j
ELSE PRINT " "
STEP 11: j = j - 1
STEP 12: PRINT a new line
STEP 13: i = i + 1
STEP 14: EXIT

Solution:

C Program:

#include <stdio.h>
int main()
{
    int lines=8;
    int i,j,k;
    for(i=1;i<lines;i++){// this loop is used to print the lines
        for(j=1;j<=lines/2;j++){// this loop is used to print numbers
            if(i==j){
                printf("%d",j);   
            }
            else if(i>4 && j==lines-i){
                printf("%d",j);   
            }
            else{
               printf(" "); 
            }            
        }
        j=j-2;
        while(j>0){  // this loop is used to print numbers
            if(i==j){
            printf("%d",j);   
            }
            else if(i>4 && j==lines-i){
                printf("%d",j);   
            }
            else{
                printf(" "); 
            }
           
            j--;
        }
        printf("\n");
    }
   return 0;
}

Output:

Java Program:

public class pattern{
     public static void main(String []args){
        
   int lines=8;
    int i,j,k;
    for(i=1;i<lines;i++){// this loop is used to print the lines
        for(j=1;j<=lines/2;j++){// this loop is used to print numbers
            if(i==j){
                System.out.print(j);   
            }
            else if(i>4 && j==lines-i){
                System.out.print(j);   
            }
            else{
               System.out.print(" "); 
            }
        }
        j=j-2;
        while(j>0){ //this loop is used to print numbers
            if(i==j){
            System.out.print(j);   
            }
            else if(i>4 && j==lines-i){
                System.out.print(j);   
            }
            else{
                System.out.print(" "); 
            }
           
            j--;
        }
        System.out.println("");
    }
     }
}
