# C Program To Perform Simple Addition, Subtract, Multiplication, Division And Remainder Of Two Numbers | LearntHub

## 1. Addition Of Two Numbers:-

Hello friends, in this post today, we will learn how we can combine the given two digits using C programming, for this, we first enter two digits and add using the + operator,  After adding, run this code then we get their sum.

Output:-
15
6
Sum of Two Numbers is:21

## 2. Subtraction Of Two Numbers:-

In this program, we will learn how we can subtract of the given two digits using C programming, for this, we first enter two digits and subtract using the - (Minus) operator,  After subtract, run this code then we get their subtraction.

Output:-
Enter Two Numbers for subtraction:
38
25
Sub of Two Numbers is:13

## 3. Multiplication Of Two Numbers:-

In this program, we will learn how we can multiply of the given two digits using C programming, for this, we first enter two digits and multiply using the * operator,  After multiply, run this code then we get their multiplication.

Output:-
Enter Two Numbers for multiplication:
8
6
Mul of Two Numbers is:48

## 4. Division Of Two Numbers:-

In this program, we will learn how we can division of the given two digits using C programming, for this, we first enter two digits and divide using the / operator,  After division, run this code then we get their division.

Output:-
Enter Two Numbers for division:
72
8
Division of Two Numbers is:9

## 5. Remainder Of Two Numbers:-

In this program, we will learn how we can find the remainder of the given two digits using C programming, for this, we first enter two digits using the % operator,  After runing this code, we get remainder of the numbers.

Output:-
Enter Two Numbers for remainder:
65
8
Remainder of Two Numbers is:1

In the above programs, we are need few things to explain which are as follow:
• In the first line #include<stdio.h> allow the program to the file of  PC, #include is preprocessor directive, it include the information to exicute specific functions from specified header files. The space between # and include is not allow at compile time.
• In the second line main() is main function. Every program contains a function which called main function. It declear the start of the function. Curly brackets({}) use to start and close functions, it uses to group statements togather in functions, which called a block.
• In the next line, N1, N2 and Sum are the variables name or variables declaration. These use to store numeric data. Int is a integer data type, which store integer number like 1,2,3,9,4 etc.
• Next is printf("......"); Here printf is buil in function in C, used to print(output) keywords on the screan, bracket uses to write a statement between brackets. Double quotes use to inclosed printed text in double quotes. Very importante notes is that every compound statement ends with semicolon (;).
• Next is scanf("%d", &Sum); Like printf, scanf is a built in function in c. It uses to read the value of the entered variables and assigns the value to specified variables. %d in the scanf or printf functions tells to the compiler that the value of  the variables should read or print as a integer. The ampersand (&) is an oprator which used to specifies the address of variables.
• Next is Sum=N1+N2; This is a particular type of expression statement which called assigment statement. This causes to addition to calculation from given numbers, plus signed(+) indicates the additional of numbers.
• Next is printf(".....%d",sum); I have already talk you about printf, double quotes, %d etch. Here %d used to print integer number which is sum i.e, sum is a integer number.
• Next and final step is return statement, it used to return a value.
