### Step by Step logic of the given program:

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

2.  Run for loop from 1 to no to print series from 1 to n:

3. Inside that loop print value of i.

## Program to print natural numbers series :

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

void main()

{

int no;

int i;

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

scanf("%d",&no);

/*Run loop from 1 to no*/

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

{

/*Print value of i with one space*/

printf("%d ",i);

}

}

``````

In these post we will learn different mathematical series programs using C programming language.

In this exercises you will learn about series programs. How to print series programs in C programming language. Below is shown some series programming exercises and examples or practice set to solve it your self.

## Guess the number game Program in C:

In this tutorial we will learn how to create Guess the number game project in C.

In these program we used two extra header files one is <stdlib.h> and second is <time.h>. <stdlib.h> header file  used because,

## Rock-Paper-Scissor Game Project using C Language:

In this tutorial we will learn how to create Rock-Paper-Scissor game project using C language.

In these program we used two new header files one is <stdlib.h> and second is <time.h><stdlib.h> header file  used because

## Data Input and output functions in C:

The C programming language  supports many library functions which includes a number of input/output functions. These functions are used to transfer the information between the computer and device(user).

### Some basic input/output functions are:

• scanf() and printf(): These two functions are used to transfer the single characters, strings and numerical values.

• getchar() and putchar(): These two functions are used to transfer single characters.

• gets() and puts(): is used to input and output strings.

### 1. How to use scanf and printf functions:

scanf() function is used to take input from user(keyboard).

printf() function is used to display output on the screen.

### Example Program:

#include<stdio.h>

void main()

{

int num;// variable definition

/*Display message and ask user to enter some number... using printf()*/

printf("Enter the number:");

/*Read the number entered by user... using scanf()*/

scanf("%d",&num);

/*Display the number with message...using printf() */

printf("You entered number is:  %d",num);

}

In above program %d is used to scan the intiger value.

If value is char then we use %c.

If value is float then we use %f and so on...

Above program shows the following output:

### 2. How to use getchar and putchar functions in our program:

getchar() function reads  a single character from the terminal and returns it as an intiger.

putchar() function is used to display these single character.

Example program:

#include<stdio.h>

void main()

{

int a;

printf("Enter a character:");

/*Here, getchar function is used to store the accepted character in variable a*/

a = getchar();

/*Display the character stored in variable a using putchar function*/

putchar(a);

}

Above program shows the following output:

### 3. How to use gets() and puts() function in C:

In simple words:

gets() function is used to accept string from user.

puts() function is used to display the string.

### Example program:

#include<stdio.h>

void main()

{

//Declare character array to store string

char str;

printf("Enter a string: ");

/*store string in array str*/

gets(str);

/*Display string on the output screen*/

puts(str);

}

Above program shows the following output:

### C Program to Print Number Heart Pattern

Ex:  Write a C program to print number heart pattern, which shows the steps to print pattern. How to write a C program to print number heart pattern, which shows steps to print pattern . C program to print number heart pattern which shows steps to print pattern.

Input from user:

Enter the number: 5

Expected output:

11      22

1111  2222

333333333

3333333

33333

333

3

This pattern is same as previous exercises star heart pattern.

Only difference is:

In this pattern we only need to replace the * with numbers 1, 2 and 3

This number's also shows the steps to print this pattern.

## Program to print number heart pattern:

#include<stdio.h>

void main()

{

int no,z;

int i,j,k;

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("1");

}

/*To print right peak*/

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

{

printf(" ");

}

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

{

printf("2");

}

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("3");

}

z-=2;

printf("\n");

}

}

### Step by step logic of the given:

For better understanding i have devided this code in two parts.

To print upper half part:

1

1  2

1  2  3

1  2  3  4

1  2  3  4  5

1. Accept input number from user.

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

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

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

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

{

printf(" ");

}

4. Run another inner for loop from 1 to i which shows columns in pattern:

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

5. Inside the second inner for loop print value of k with one space:

printf("%d ",k);

6. After that outside the block of  inner for loop print next line \n for print new row.

To print lower half part:

1  2  3  4

1  2  3

1  2

1

1. Run outer loop from 1 to no-1 which shows rows in pattern:

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

2. Run inner for loop from 1 to i to print spaces:

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

{

printf(" ");

}

3. Run another one inner for loop from 1 to no-i and inside the loop print value of  k :

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

{

printf("%d ",k);

}

4. Last print \n for new row.

## Program to print diamond number pattern:

#include<stdio.h>

void main()

{

int no,i,j,k;

printf("Enter the number:");

scanf("%d",&no);

/*To print upper part*/

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

{

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

{

printf(" ");

}

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

{

printf("%d ",k);

}

/*For next row*/ printf("\n");

}

/*To print lower part*/

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

{

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

{

printf(" ");

}

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