How does C program to add two integers work?

add integers


Courtesy: Programiz.com

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", &number1, &number2);

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

sum = number1 + number2;

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

printf("%d + %d = %d", number1, number2, sum);

Function prototype and definition

Function Prototype: A function prototype is also known as a function declaration. A function declaration tells the compiler about a function name and how to call the function. It defines the function before it is being used or called. A function prototype needs to be written at the beginning of the program. Syntax: return-type function-name ( arg-1, arg-2, ... ); Example: void addition( int, int ); Function Definition: A function definition defines the functions header and body. A function header part should be identical to the function prototype. Function return type Function name List of parameters A function body part defines function logic. Function statements Syntax: return-type function-name( arg-1, arg-2, ... ); {         //... function body } Example: void addition( int x, int y) {     printf("Addition is = %d ",(x+y)); } Drafted on 🌏 by, Jal ☮ peace

Actual and Formal Parameters

User-defined Function: User-defined is a function that is not part of a library but is defined by the user itself. Actual Parameters: Values that are passed to the called function from the main function are known as Actual parameters. Actual parameters are also called "Arguments". Formal Parameters: The variables declared in the function prototype or definition are known as Formal parameters. Example: Actual parameters: void main() {      int a=5, b=6;     add(a, b); } Here "a" and "b" are actual parameters in the call add(a, b). Formal parameters: void add( int x, int y) {     printf("Addition is = %d",(x+y)); } Here "x" and "y" are formal parameters in the statement void add( int x, int y). When a method is called, the formal parameter is temporarily "bound" to the actual parameter. Drafted on 🌏 by, Jal ☮ peace
