C program to print square number pattern 2

Ex: Write a C program to print square number pattern 2. How to write a C program to print square number pattern 2. C program to print square number pattern 2.

Input from user:

Enter the number: 5

Expected output:

11111

22222

33333

44444

55555

Given pattern is same as previous square number pattern:

11111

11111

11111

11111

11111

Difference is:

In this pattern we only need to replace the 1 with value of i .

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++)

{

/*print value of i*/

               printf("%d",i);

}

/*for new line*/

        printf("\n");

}

}

Above program shows the following output:

Input from user:

Enter the number: 5

Expected output:

2       2

2       2

2       2

22222

  Step by step logic of the given program:

To understand this pattern, first you need to understand previous exercises hollow square star pattern.

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

2. Run outer loop from 1 to no, which shows rows in pattern.

3. Run inner loop from 1 to no to print columns in pattern.

4. Inside the inner loop using if statement give conditions to print number:

if(i==1||i==no||j==1||j==no)

5. Otherwise print spaces, to make it hollow.

6. Outside the block of inner for loop, print newline \n.

Program:

#include<stdio.h>

void main()

{

int i,j,no;

printf("Enter the number:");

scanf("%d",&no);

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

{

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

{

/*Conditions to print number*/
                if(i==1||i==no||j==1||j==no)

{

    /*you can enter any number(symbol) here*/         
                    printf("2");

}

else

{

    /*To print spaces*/

                 printf(" ");

}

}

/*For next row*/

            printf("\n");

}

}

  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>

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++)

{

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

{

}

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

{
