Factorial Program in Java:

Factorial of a number means the product of all positive descending integers.

for example: If we want to calculate factorial of 5 then it will be written as

5 x 4 x 3 x 2 x 1 = 120 . So 120 is the factorial of 5.

Program to Print Factorial of a given number:

Fibonacci Series In Java:

The fibonacci series is a series where the next number is the sum of previous two numbers.

for examples: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55 etc.

above you can see first two numbers of fibonacci series are 0 and 1.

C Program To Display User Details Using ID

EX: Write a C program to display user details using id. How to write a C program to display user details. C program to display student details using their ID.

In this article, we will learn how to write a C program that displays user details based on a provided ID. In this program, we will use a switch case to print user details... But you can also do this program using if-else-if statements.

Here's a step-by-step guide for creating this program:

Step 1: Include the Standard Input-Output Header

First, include the standard input-output library, which allows us to use functions like printf and scanf for input and output operations.

#include<stdio.h>

Step 2: Start the main Function

Every C program starts executing from the main function. This is where we'll write the logic of our program.

int main() {

Step 3: Declare an Integer Variable

We'll declare an integer variable id to store the ID entered by the user.

int id;

Step 4: Accept User Input

Prompt the user to enter their ID using printf and store the input in the id variable using scanf.

// Accept id from user
printf("Enter your id: ");
scanf("%d", &id);

Step 5: Use a switch Statement to Match the ID

The switch statement allows us to execute different code blocks based on the value of the id. We'll check for specific IDs and print the corresponding user details.

//Switch the value of id
switch(id) {

Step 6: Define Cases for Specific IDs

For each case, we'll match a specific ID and print the details for that user. If the ID doesn't match any case, the default case will prompt the user to enter a valid ID.

// Match id with cases
        case 11:
            printf("Information of id %d is:\n", id);
            printf("Name: Omkar Lokhande\nContact: 123456***\nAdd: Kalamb\n");
            break;

        case 12:
            printf("Information of id %d is:\n", id);
            printf("Name: Akash Sutar\nContact: 1234***\nAdd: Kalamb\n");
            break;

        case 13:
            printf("Information of id %d is:\n", id);
            printf("Name: Rusty Shackleford\nContact: 12456***\nAdd: California\n");
            break;

        default:
            printf("Please Enter Valid Id\n");   
    }

Step 7: End the main Function

Finally, we'll return 0 to indicate that the program has executed successfully.

return 0;
}

C program to display user details using id :

Here, is the complete program to display user details using id.


#include<stdio.h>

int main()
{
    int id;
    //Accept id from user
    printf("Enter your id: ");
    scanf("%d",&id);
    //Switch the value of id
    switch(id) {
        //Match id with cases
        case 11:
        printf("Information of id %d is:\n",id);
        printf("Name: Omkar Lokhande\nContact: 123456***\nAdd: kalamb");
        break;

        case 12:
        printf("Information of id %d is:\n",id);
        printf("Name: Akash Sutar\nContact: 1234***\nAdd: kalamb");
        break;

        case 13:
        printf("Information of id %d is:\n",id);
        printf("Name: Rusty Shackleford \nContact: 12456***\nAdd: California");
        break;

        default:
        printf("Please Enter Valid Id");   
    }
    return 0;
}

Above program will show the following output:

Enter your id: 13

Information of id 13 is:

Name: Rusty shackleford

Contact: 123456***

Add: California
