📘 Step Learning

In this example, the user is asked to enter two integers. Then, the sum of these two integers is calculated and displayed on the screen.

To understand this example, you should have the knowledge of the following C programming topics:

C Data Types
C Variables, Constants and Literals
C Input Output (I/O)
C Programming Operators

Flow chart

💻 Program Code

#include"stdio.h"
 void main()
	{
	int num1, num2, sum; 
	printf("Enter two no: ");
 	scanf("%d%d",&num1,&num2);
	sum = num1 + num2;
        printf("sum=%d \n", sum );    
}

🖥 Program Output

Enter two no: 2 3
sum=5
Press any key to continue . . .

📘 Explanation

Algorithm:

Step 1: Start
Step 2: Declare variable number1, number2 and sum
Step 3: Read Variable number1, number2
Step 4: Perform operation (sum= number1+ number2)
Step 5: Print sum variable
Step 7: Stop

In this program, the user is asked to enter two integers. These two integers are stored in variables?number1?and?number2?respectively.

printf("Enter two integers: ");
scanf("%d %d", &num1, &num2);

Then, these two numbers are added using the?+?operator, and the result is stored in the?sum?variable.

sum = num1 + num2;

Finally, the printf() function is used to display the sum of numbers.

printf("sum=%d \n", sum );

🎯 How to learn from this example

First understand the algorithm carefully. Then study the program line-by-line and compare it with the output. Finally, review the explanation section to strengthen your logic and programming understanding.

🔥 Practice suggestion

Rewrite the program without looking at the code. Modify values, conditions or logic and run it again. This helps improve confidence and strengthens coding skills much faster.
