Code in code::blocks: Star pattern program in c source code

1.Print a pattern

         *
      *  *
   *  *  *
*  *  *  *

To print this pattern we have to use three for loop.Inside the first loop there

will be two loop, one is for controlling the spacing factor and another for

printing the stars.Constant value of First loop is used in second inner loop to

decided the number of stars.

Here is the source code copy and paste it on code::blocks and run the program you

will see the result.

Source code

#include<stdio.h>
int main() {
 char star = '*';
 int i, j, num = 4, spc;
 for (i = 1; i <= 5; i++) {
     for (spc = num; spc >= 1; spc--) {  // Spacing factor
           printf("  ");
  }
  for (j = 1; j <= i; j++) {
       printf("%2c", star);
  }
  printf("\n");
  --num;   // Controls the spacing factor
 }
 return 0;
}

2.Print a pattern

*                   *
* * *           * * *
* * * * *   * * * * *
* * * * * * * * * * *

This pattern is also simple just joining two triangle in a little different way.Here odd number

of star is printed from first and last position.

#include<stdio.h>
int main()
{
 //char star = '*';
 int i,j;
 for (i=1;i<=7;i++)
 {
     for(j=0;j<11;j++)
     {
         if(i%2!=0)
         {
         if(j<= i-1||j>=11-i)
          printf("* ");
         else
          printf("  ");
         }

     }
     printf("\n");
 }

3.Print a pattern

                     *
                  * * *
                * * * * *
              * * * * * * *
                * * * * *
                  * * *
                    *

        for(l=n;l>i;l--)
