6.Inverted triangle pattern with left spacing

 

I have added numbers to make you understand how we will create this pattern using for loop

• As we know we first see how many lines of code needs to be printed, in this case it is 9 so i will iterate from 1 to n
• Since we will take user input it can be simply n which will be taken from user
• Here there is a difference that only stars are not being printed
• Along with the stars space is also being printed
• Inside outer i for loop there will be two loops one for star and another for space
• For space we will use variable s
• As we can see for i =1 there is no space,for i=2 there is 1 space and so on
• So we can say that s will iterate from 1 to i-1
• As for the pattern as we have seen before
• j will iterate from i to n

Code

#include<stdio.h>

#include<conio.h>

void main(){

int i,j,n,s;

clrscr();

printf("Enter number of lines ");

scanf("%d",&n);

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

    {

          for(s=1;s<=i-1;s++)

               {

                printf(" ");

                 }

          for(j=i;j<=n;j++)

               {

                 printf("*");   

                   }

           printf("\n");

     }

getch();

}

Note: scanf is used for taking user input
