π Calculate sum of two integers taken as input
Write a C program that takes two integer numbers as input from the user. The program should then calculate the sum of these two integers and print the result to the console.
{programTitle}
π» Code:
#include <stdio.h>
int main() {
int num1, num2, sum;
printf("Enter the first integer: ");
scanf("%d", &num1);
printf("Enter the second integer: ");
scanf("%d", &num2);
sum = num1 + num2;
printf("The sum of %d and %d is: %d\n", num1, num2, sum);
return 0;
}
π‘ Approach
Here's a straightforward approach for calculating the sum of two integers in C:
Step 1: Declare three integer variables:
num1, num2, and sum. num1 and num2 will store the input numbers, and sum will hold their sum.
Step 2: Prompt the user to enter the first integer using printf.
Step 3: Read the first integer from the user and store it in the num1 variable using scanf.
Step 4: Prompt the user to enter the second integer using printf.
Step 5: Read the second integer from the user and store it in the num2 variable using scanf.
Step 6: Calculate the sum of num1 and num2 and store the result in the sum variable: sum = num1 + num2;
Step 7: Display the calculated sum to the user using printf.

Write a C program that takes two integers as input from the user. Calculate the sum of these two integers and display the result to the console.
π» Code:
#include <stdio.h>
int main() {
float userInput;
printf("Enter a float number: ");
scanf("%f", &userInput);
printf("You entered: %fn", userInput);
return 0;
}π‘ Approach
Step 1: Include the standard input/output library. (This provides functions like
printf and scanf).
Step 2: Declare a float variable to store the user's input. (This variable will hold the float value).
Step 3: Prompt the user to enter a float number using printf. (This tells the user what to do).
Step 4: Read the float input from the user using scanf and store it in the declared float variable. (Use the correct format specifier %f for float).
Step 5: Display the stored float value back to the user using printf. (Again, use the correct format specifier %f for float).
Step 6: Return 0 from the main function. (Indicates successful program execution).

β€οΈ Understood | π Not Understoodπ Get float input from the user and display it
Write a C program that prompts the user to enter a floating-point number. The program should then read the input from the user and display the entered floating-point number to the console with appropriate formatting.
π» Code:
#include <stdio.h>
int main() {
int userInput;
printf("Enter an integer: ");
scanf("%d", &userInput);
printf("You entered: %dn", userInput);
return 0;
}π‘ Approach
Step 1: Include the standard input/output library: This provides functions like
printf (for output) and scanf (for input).
Step 2: Declare an integer variable: This variable will store the integer value entered by the user.
Step 3: Prompt the user for input: Display a message on the screen asking the user to enter an integer.
Step 4: Read the integer input using scanf: Use scanf to read the integer entered by the user and store it in the declared integer variable.
Step 5: Display the entered integer using printf: Use printf to display the value stored in the integer variable back to the user, confirming their input.
Step 6: Return 0 from the main function: This indicates successful execution of the program.

β€οΈ Understood | π Not Understoodπ Get integer input from the user and display it
Write a C program that prompts the user to enter an integer. After the user inputs an integer, the program should then display the entered integer back to the user on the console.
π» Code:
#include <stdio.h>
int main() {
printf("Your Name: John Doen");
printf("Street Address: 123 Main Streetn");
printf("City: Anytownn");
printf("State: CAn");
printf("Zip Code: 91234n");
return 0;
}π‘ Approach
Step 1: Include the standard input/output library. This library contains functions like
printf that we will use to print to the console.
Step 2: Create the main function. This is the entry point of your C program.
Step 3: Use printf statements to display your name and address. Each piece of information (name, street, city, etc.) can be on a new line for readability.
Step 4: Return 0 from the main function to indicate successful execution of the program.

Write a C program that prints your full name and address to the console. The output should be formatted in a readable manner, with your name on the first line, followed by your street address, city, state, and zip code each on subsequent lines.
π» Code:
#include <stdio.h>
int main() {
printf("Hello, World!n");
return 0;
}π‘ Approach
Step 1: Include the standard input/output library: This provides functions for printing text to the console. We do this using
#include <stdio.h>.
Step 2: Define the main function: The main function is the entry point of every C program. It's where the program begins execution. Start it with int main() {.
Step 3: Print "Hello, World!" to the console: Use the printf function to display the text. printf("Hello, World!\n"); will print the message, and \n adds a newline character to move the cursor to the next line.
Step 4: Return 0 from the main function: This indicates that the program executed successfully. Add return 0; before closing the main function.
Step 5: Close the main function: Add a closing curly brace } to end the main function.

β€οΈ Understood | π Not Understoodπ Hello World program
Write a C program that prints the phrase "Hello, World!" to the console. This exercise serves as a fundamental introduction to C syntax and the standard output function
printf.π» Code:
#include <stdio.h>
int main() {
printf("Hello, World!n");
return 0;
}π‘ Approach
Step 1: Open a Text Editor: Use a basic text editor (like Notepad on Windows, TextEdit on macOS, or gedit/nano on Linux) to create a new file.
Step 2: Write the C Code: Type the following C code into the text editor:
#include <stdio.h>
int main() {
printf("Hello, World!\n");
return 0;
}
.c extension, for example, hello.c. Choose a location where you can easily find it (e.g., your desktop).
Step 4: Open a Command Prompt/Terminal: Open the command prompt (Windows) or terminal (macOS/Linux).
Step 5: Navigate to the Directory: Use the cd command to navigate to the directory where you saved the hello.c file. For example, if you saved it on your desktop, you might use cd Desktop (Windows) or cd ~/Desktop (macOS/Linux).
Step 6: Compile the Code: Use a C compiler (like GCC) to compile the code. Type the following command and press Enter: gcc hello.c -o hello (This creates an executable file named "hello"). If you are on Windows and GCC is not recognized, you might need to configure your system's PATH environment variable to include the directory where GCC is installed.
Step 7: Run the Executable: Execute the compiled program.
On Windows, type hello.exe and press Enter.
On macOS/Linux, type ./hello and press Enter.
