printf("Enter Any Number:");
scanf("%d",&n);
for(i=1;i<=10;i++)
printf("%d\t",i*n);

}

Explain Program

Step :1

#include<stdio.h>

Standard Input/Output header file.

Step :2

void main()

 defines the main function which is the entry point of any C program.

Step :3

int n, i;

1. n: to store the number entered by the user.
2. i: loop control variable for the for loop.

Step :4

printf("Enter Any Number:");

Prints a message to the screen to the user to enter a number

Step :5

scanf("%d", &n);

• input from the user and stores it in the variable n.

• %d is used to read an integer.

• &n means the address of n, because scanf needs to modify the variable.

Step :6

for(i = 1; i <= 10; i++)

1. A for loop that runs from i = 1 to i = 10.

1. Purpose: to generate and display the multiplication table of the number n

Step :7

 printf("%d\t", i * n);

• In each iteration, prints i * n (which is a multiplication result).

• \t is a tab character, used to separate the numbers with space.

 C Program for Printing Alphabet Patterns

Example :-

#include<stdio.h>

void main()
{
int r,c;

clrscr();
for(r=65;r<=69;r++)
{
for(c=r;c>=65;c--)
{
printf("%c",r);
}
printf("\n");
}
getch();
}

Explain Program

Step :1

#include<stdio.h>

standard input/output header file

Step :2

void main()

Declares the main function

Step :3

Variable Declarations

int r, c;

• Two integer variables r [rows] and c [columns] are declared.

Step :4

 Outer  Loop : 

for (r = 65; r <= 69; r++)

 loop iterates from ASCII value 65 (' A ') to 69 (' E ')

So r takes values:

	ASCII Char
65	A
66	B
67	C
68	D
69	E

Step :5

Inner for Loop:

 for (c = r; c >=  65; c--)

This loop prints r [ASCII character]  repeatedly, starting from c = r down to c = 65.

• printing the same character r, multiple times.

• The number of times is (r - 65 + 1).

Step :6

Iteration : 1 

r = 65 (' A ')

1. Inner loop:
2.  c = 65 → 1 time
3. Prints: A

Step :7

Iteration 2: 

r = 66 ('B')

• Inner loop:
•  c = 66, 65 → 2 times

• Prints: BB

Step :8

Iteration 3:

 r = 67 ('C')

• Inner loop:
•  c = 67, 66, 65 → 3 times

• Prints: CCC

Step :9

Iteration 4:

 r = 68 (' D ')

1. Inner loop:
2.  c = 68, 67, 66, 65 → 4 times
3. Prints: DDDD

C Program for Printing Alphabet Patterns

Output :-

A
BB
CCC
DDDD

Step 2

int main()

 function, the entry point of your C program.

Step 3

int i, j, row;

Declares three integer variables 

i: outer loop counter (for rows) 

j: inner loop counter (for printing *) 

row: stores the number of rows entered by the user

Step 4

printf("enter the number");

 user to input the number of rows.

Step 5

scanf("%d", &row);

Takes input from the user and stores it in the row variable. 

%d is for reading an integer. 

&row means you're passing the address of the variable row to store the user input.

Step 6

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

This is the outer loop. 

It runs from 1 to the number entered by the user (row).

Step 7

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

This is the inner loop. 

For each row i, it prints i number of asterisks *.

Step 8

 printf("*");

Prints a single asterisk * without moving to the next line.

Step 9

printf("\n");

 moves the cursor to the next line.

C Program to Check Number is prime or Not prime

Explain Program

Step :1

#include <stdio.h>

 Standard Input Output library, which is required for functions like printf() and scanf().

Step :2

void main()

This is the main function, where program execution starts.

Step :3

int a, i, flag = 0;

 stores the number  a, b entered by the user.

Step :4

printf ("enter a positive integer");

scanf ("%d", &a);

 user to enter a number.

 scanf () reads the input and stores it in variable a.

Step :5

if (a == 0 || a == 1)

    flag=1;

0 and 1 are not prime numbers by definition.

Step :6

for (i = 2; i <= a / 2; i++)

{

    if (a % i == 0)

    {

        flag = 1;

        break;

    }

}

loop check if any number between 2 and a/2 divides a completely

Step :7

if (flag == 0)

    printf("%d is prime number ", a);

else

    printf("%d is not prime number", a);

If no divisor was found (flag is still 0), the number is prime.

Output 

 enter a positive integer 133
   133 is not prime number
