# Rectangle & Pyramids Pattern in C++

By | September 29, 2021

Here in this article, we have covered some of the important Rectangle and Pyramids patterns using the C programming language. The logic we have used here to create all the patterns is most important when it comes to design a pattern in any language, and with the same logic, we can make those patterns in any other programming language. The logic behind these patterns helps you to understand the logic and working of loops, conditional statements, and print statements.

### Rectangle

```#include<stdio.h>
#include <conio.h>

void main()
{
int l , b,i,j;
clrscr();
printf("Enter the Length of Rectange: ");
scanf("%d",&l);
printf("Enter the breadth of Reactangle: " );
scanf("%d",&b);

for(i=0;i<l;i++)
{
for(j=0; j<b ;j++)
{  if(i==0||i==l-1||j==0||j==b-1)
printf("*");
else
printf(" ");
}
printf("\n");
}

getch();
}```

Output:

```Enter the Length of Rectangle: 10
Enter the breadth of Rectangle: 20```

### Pyramids

 Pyramids Codes Output ```#include #include void main()      {        int l ,i,j;        clrscr();       printf("Enter the Length of Pyramid: ");        scanf("%d",&l);       for(i =0;i #include void main()      {        int l ,i,j;        clrscr();      printf("Enter the Length of Pyramid: ");       scanf("%d",&l);       for(i =l;i >= 0; i--)           {             for(j=0; j<=i;j++)              {                  printf("*");              }           printf("\n");            }        getch();      }``` ```Enter the Length of Pyramid: 6 *  *  *  *  *  * *  *  *  *  * *  *  *  * *  *  * *  * *``` Code Output ```#include #include void main() { int i, j, l, k = 0; printf("Enter the Length of Pyramid: "); scanf("%d",&l); for(i = 1; i <= l; ++i, k = 0) {     for(j = 1; j <= l – i; ++j)     {            printf(" ");    }     while(k != 2 * i-1)       {          printf("*");         k++;          }     printf("\n"); } getch(); }``` ```Enter the Length of Pyramid: 6           *         *   *       *   *   *     *   *   *   *   *   *   *   *   * *   *   *   *   *   *``` Code Output ```#include #include void  main() { int i, j, l,k = 0; printf("Enter the Length of Pyramid: "); scanf("%d",&l); for (i = 1; i <= l; i++) { for (j = i; j < l; j++) { printf(" "); } while (k != (2 * i - 1)) { if (k == 0 || k == 2 * i - 2) printf("*"); else printf(" "); k++; } k = 0; printf("\n"); } for (i = 0; i < 2 * l - 1; i++) { printf("*"); } getch(); }``` ```Enter the length of Pyramid: 6        *       *  *     *      *   *          * *            * *   *   *   *   *   *``` Code Output ```#include #include void  main() { int i, j, l,k = 0; printf("Enter the Length of Pyramid: "); scanf("%d",&l); for (i = 0; i < l; i++) { printf("*"); } for(i=l; i>=1; –i) { for(j=0; j < l-i; ++j) while (k != (2 * i – 1)) { if (k == 0 || k == 2 * i – 2) printf("*"); else printf(" "); k++; } k = 0; printf(“\n”); } }``` ```Enter the Length of Pyramid: 6 ***** *  * * * ** *```
