Addition, Subtraction, Multiplication, and Division in C

To perform addition, subtraction, multiplication and division of any two number in C programming, you have to ask to the user to enter the two number and then ask to enter the operator to perform the mathematical operations.

C Programming Code to Perform Addition, Subtraction, Multiplication and Division

Following C program ask from user to enter the two number to perform addition, subtraction, multiplication and division of the entered two numbers:

/* C Program - Addition, Subtraction, Multiplication, and Division */
		 
#include<stdio.h>
#include<conio.h>
void main()
{
	clrscr();
	int a, b, res;
	printf("Enter two number :");
	scanf("%d%d",&a,&b);
	res=a+b;
	printf("\nAddition = %d",res);
	res=a-b;
	printf("\nSubtraction = %d",res);
	res=a*b;
	printf("\nMultiplication = %d",res);
	res=a/b;
	printf("\nDivision = %d",res);
	getch();
}

When the above c program is compile and executed, it will produce the following result:

c program addition subtraction multiplication division

C Programming Code to Perform Mathematical Operations

Following C program ask to the user to enter the two number along with operator to perform particular mathematical operation (addition, subtraction, multiplication and division) according to user:

/* C Program - Mathematical Operations */
		
#include<stdio.h>
#include<conio.h>
void main()
{
	clrscr();
	int a, b;
	char ch;
	printf("Enter first Number :");
	scanf("%d",&a);
	printf("Enter second Number :");
	scanf("%d",&b);
	printf("Enter operator (+, -, *, /) :");
	scanf(" %c",&ch);
	if(ch=='+')
		printf("Result = %d",a+b);
	else if(ch=='-')
		printf("Result = %d",a-b);
	else if(ch=='*')
		printf("Result = %d",a*b);
	else if(ch=='/')
		printf("Result = %d",a/b);
	else
		printf("Wrong Operator!!!");
	getch();
}

When the above C program is compile and executed, it will produce the following result:
