C program to print half left side of the pyramid star pattern

 Ex: Write a C program to print half left side of the pyramid star pattern. How to write a C program to print half left side of the pyramid star pattern. C program to print half left side of the pyramid star pattern.


Input from user:

Enter the number:

5


Expected output:

        *

      **

    ***

  ****

*****



  Step by step logic of the given program:


1. Accept input number from user declare variable say no.


2. Run outer loop from 1 to no which shows the number of rows in pattern:

for(i=1;i<=no;i++)


3. Run first inner loop from i to no-1 to print spaces:

for(j=i;j<no;j++)


4. Run second inner loop from 1 to i to print star:

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


5. For next row print \n.




Program:


#include<stdio.h>

void main()

{

int no,i,j,k;

printf("Enter the number:\n");

scanf("%d",&no);

/*Run loops*/

for(i=1;i<=no;i++)

{

for(j=i;j<no;j++)

{

    printf(" ");

}

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

{

    printf("*");

}

/*For new row*/

        printf("\n");

}


}


Above program shows the following output:
