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

💻 Program Code

#include"stdio.h" 
 void main()
	{
        // variable declaration
	int num1, num2, subResult; 

	printf("Enter two no: ");
 	scanf("%d%d",&num1,&num2);
	subResult = num1 - num2;

       // Print result
       printf("subtraction result =%d \n", subResult);
    
}

🖥 Program Output

Enter two no: 6 3
sum=3
Press any key to continue . . .

📘 Explanation

Algorithm:

Step 1: Start
Step 2: Declare variable number 1, number 2 and subResult
Step 3: Read Variable number 1, number 2
Step 4: Perform operation (subResult = num1 - num2)
Step 5: Print subResult variable
Step 7: Stop

🎯 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.
