In our day-to-day life, we do calculations like addition, subtraction, multiplication, and division on numbers such as integers, real numbers, whole numbers, etc.
We perform such arithmetic operations in the C programming language using our c programs.
This article by Simplilearn will help you understand how to execute the addition of two numbers programs in detail.
How to Execute the Addition of Two Integer Numbers Program?
Using the addition operator(+), we will perform addition operations on two operands. From the following code, a and b are the operands, and the sum is the variable. Once the addition is performed, the result is stored in the variable sum and displayed as an output.
Now you know the logic of a program. Let's have a look at the program code.
int a=10, b=5, sum;
printf("The addition of %d and %d is: %d",a,b,sum);
Look at the below-given diagram to understand it in a better way.
The values of a and b are 10 and 5, respectively. By adding 10+5, the output stored in the sum variable is 15.
Now, let's execute another program to perform the addition of two numbers by taking inputs from the user.
printf("Enter two values for a and b");
printf("Addition of two numbers %d and %f is: %f",a,b,sum);
From the above code, we are asking the user to enter the values for the variable a of type int and b of type float using scanf(). And the values entered for a and b are 2 and 4.6, respectively. Using printf(), we are printing the result 6.600000 floating value as an output.
Addition of Two Integer Numbers Using Function in C
The logic of a C program is easy to understand, and the whole C program can be divided into individual and functional units. It means every function in the program acts as an independent unit to perform a specific task or an operation and is also capable of running separately.
The below code has a function with an argument that performs the addition operation. And in the main function, there is a function call, and the result is printed.
int sum(int a, int b)
printf("Enter two numbers for a and b\n");
printf("Addition of two numbers is:%d",result);
With that, you can conclude this tutorial on how to execute the addition program in C.
