C program to print square number pattern 1

Ex: Write a C program to print given square number pattern. How to write a C program to print given square number pattern. C program to print given square number pattern.

Input from user:

Enter the number: 5

Expected output:

11111

11111

11111

11111

11111

  Step by step logic of the given program:

To print this pattern, first you need understand square star pattern:

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

2. Run outer for loop  from 1 to no to print number of rows.

3. Run inner for loop from 1 to no to print number of columns.

4. Inside the inner loop print 1.

5. For next row print new line \n.

Program:

#include<stdio.h>

void main()

{

int no;

int i,j;

printf("Enter the number:");

scanf("%d",&no);

/*Loop to print rows */

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

{

          /*Loop to print columns */

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

{

/*you can add any number here to print their pattern*/

                      printf("1");

}

/*for new line*/

printf("\n");

}

}

  Step by step logic of the given program:

1. Accept input number from user.

2. To print upper part of the pattern:

• Print left peak:

     **

   ****

• Print right peak:

     **

   ****

3. After that print lower part means inverted triangle:

*********

  *******

    *****

      ***

        *

4. Then you will get heart shape pattern:

    **     **

  ****  ****

  *********

    *******

      *****

        ***

          *

Program:

#include<stdio.h>

void main()

{

int no,i,j,k,z;

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

scanf("%d",&no);

/*To print upper part*/

z=no*2;

for(i=no/2;i<=no;i=i+2)

{

/*To print left peak */

for(j=1;j<no-i;j=j+2)

{    

                    printf(" ");

}

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

{

printf("*");

}

/*To print right peak*/

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

{

    printf(" ");

}

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

{

printf("*");

}

printf("\n");

}

/*To print lower part means inverted triangle*/

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

{

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

{

printf(" ");

}

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

{

printf("*");

}

z-=2;

printf("\n");

}
