C Programs for addition, subtraction, multiplication and division of two numbers

Written a C Program for addition, subtraction, multiplication, and division for two given numbers by the user.

Read this article till to end and understand the program's logics of arithmetic operations.

The C programs for Arithmetic Operations

1. Addition    2. Subtraction    3. Multiplication    4. Division

Program Logic : For those operations, we follow those steps for all programs

1. We write a c program for getting 2 values from the User that was only Integer.

2. Performing arithmetic operation by using that operator, And stored result in another variable.  -  [You can also use the Assignment operator.]

3. Final answer will display by using " printf() ".

" Read it and try its own self. "

1. Write a C program to find an Addition of two numbers

The C Program Codes for Addition, The Addition can do in Three ways. 

1. Using the sum function which uses for addition.

2. Create a small code of addition as given below.

3. Direct print the answer of addition by simply writing a+b.

Here, We have written C Program to display the Addition of the given two Numbers.

" You can add more numbers by adding more variables "

#include<stdio.h>
#include<math.h>
int main() {
    //Declaration of variable
    int number1,number2,sum;
    // Get valuse for numbers by user
    printf("\nEnter first number = ");
    scanf("%d",&number1);
    printf("\nEnter second number = ");
    scanf("%d",&number2);

    // Addition by using SUM Function
    // sum=sum(number1,number2);

    // Addition Without Function
    sum=number1+number2;

    // Display Answer of Addition 
    printf("Answer of Addition = %d",sum);

    // Direct display the answer of Addition without use other variable
   /* printf("Answer of Addition = %d:,number1+number2); */
    return 0; 
    }

OUTPUT :

Enter first number: 10

Enter second number: 20

Answer of Addition = 30 code-box

Now, we see a subtraction of two numbers.

2. Write a C program to find the Subtraction of two numbers.

There was the same logic used as an upper program. Here we just change the arithmetic operator ' + ' to ' - '.

#include<stdio.h>
#include<math.h>
int main() {
    //Declaration of variable
    int number1,number2,sub;
    // Get valuse for numbers by user
    printf("\nEnter first Digit = ");
    scanf("%d",&number1);
    printf("\nEnter second Digit = ");
    scanf("%d",&number2);

    // Subtraction
    sub=number1-number2;

    // Display Answer of Subtraction
    printf("Answer of Addition = %d",sub);

    // Direct display the answer of Subtraction without use other variable
    // By place '-' between number1 and number2
    printf("Answer of Subtraction = %d:,number1-number2);
    return 0; 
}

OUTPUT :

Enter first number: 10

Enter second number: 20

Answer of Addition = 10 code-box

3. Write a C program to find the Multiplication of two numbers.

There was the same logic used as an upper program. Here we just change the arithmetic operator ' - ' to  ' * '.

For the C language and many other languages the star symbol  * used for multiplication. In a C language is also used for the pointer.

#include<stdio.h>
#include<math.h>
int main() {
    //Declaration of variable
    int number1,number2,multi;
    // Get valuse for numbers by user
    printf("\nEnter first Digit = ");
    scanf("%d",&number1);
    printf("\nEnter second Digit = ");
    scanf("%d",&number2);

    // Subtraction
    multi=number1*number2;

    // Display Answer of Multiplication
    printf("Answer of Multiplication= %d",multi);

    // Direct display the answer of Multiplivation without use other variable
    // By place '*' between number1 and number2
    printf("Answer of Multiplication = %d:,number1*number2);
    return 0; 
}

OUTPUT :

Enter first number: 10

Enter second number: 20

Answer of Addition = 200 code-box

4. Write a C program to find the Division of two numbers.

There was the same logic used as an upper program. Here we just change the arithmetic operator ' * ' to  ' / '.

For the C language, a single Forward slash ' / ' is for Division, and double ' // ' use for Single line comment.

#include<stdio.h>
#include<math.h>
int main() {
    //Declaration of variable
    int number1,number2,divi;
    // Get valuse for numbers by user
    printf("\nEnter first Digit = ");
    scanf("%d",&number1);
    printf("\nEnter second Digit = ");
    scanf("%d",&number2);

    // Subtraction
    divi=number1/number2;

    // Display Answer of Division
    printf("Answer of Division = %d",divi);

    // Direct display the answer of Division without use other variable
    // By place '*' between number1 and number2
    printf("Answer of Division = %d:,number1/number2);
    return 0; 
}

OUTPUT :

Enter first number: 25

Enter second number: 5

Answer of Addition = 5 code-box

Those are the C program for performing Arithmetic operations. Those programs are the same we just change out the arithmetic oerators. [ Calculation symbols like +, -, *, / ]
