#Operator :
Operators in C program is special symbol or word which directs the compiler to perform arithmetical or logical works, i.e. the characters which is used in C for special purpose so this character is called operators.
#Different types of operators :
Arithmetic operator
Unary operator
Relational operator
Logical operator
Assignment operator
Conditional operator
#Arithmetic Operators List :
# Arithmetic expressions:
An arithmetic expression is a combination of variables, constants, and operators.For example,
Problems…
1) (a) Write a program that read two integer and display sum.
#include
<stdio.h>
int main ()
{
int a, b, c;
printf("Enter
the value of a : ");
scanf("%d",
&a);
printf("Enter
the value of b : ");
scanf("%d",
&b);
c =a+b;
printf("Sum
of a and b is %d ", c);
}
(1)(b) Write a program that read two floating point and display sum.
#include
<stdio.h>
int main ()
{
float a, b, c;
printf("Enter
the value of a : ");
scanf("%f",
&a);
printf("Enter
the value of b : ");
scanf("%f",
&b);
c =a+b;
printf("Sum
of a and b is %f ", c);
}
2) Write a program that subtracts two integer.
#include
<stdio.h>
int main ()
{
int a, b, c;
printf("Enter
the value of a :");
scanf("%d",
&a);
printf("Enter
the value of b :");
scanf("%d",
&b);
c =a-b;
printf("a
- b = %d", c);
}
3) Write a program that read two integer and display product.
#include
<stdio.h>
int main ()
{
int a, b, c;
printf("Enter
the value of a : ");
scanf("%d",
&a);
printf("Enter
the value of b : ");
scanf("%d", &b);
c =a*b;
printf("Product
of a and b is %d ", c);
}
(4) (a) Write a program that divide two integer.
#include
<stdio.h>
int main ()
{
int a, b, c;
printf("Enter
the value of a: ");
scanf("%d",
&a);
printf("Enter
the value of b: ");
scanf("%d",
&b);
c =a/b;
printf("a
divide b is = %d", c);
}
(4) (b) Write a program that divide two floating point.
#include
<stdio.h>
int main ()
{
float a, b, c;
printf("Enter
the value of a: ");
scanf("%f",
&a);
printf("Enter
the value of b: ");
scanf("%f",
&b);
c =a/b;
printf("a
divide b is = %f", c);
}
5) Write a program that read two integer and display reminder.
#include
<stdio.h>
int main ()
{
int a, b, c;
printf("Enter
the value of a: ");
scanf("%d",
&a);
printf("Enter
the value of b: ");
scanf("%d",
&b);
c =a%b;
printf("Remainder
= %d", c);
}
(6) (a) Write a program that read radius of a circle and display its area.
#include
<stdio.h>
void main ()
{
float r, area;
printf("Enter
the radius : ");
scanf("%f",
&r);
area =
3.1416*r*r;
printf("The
area of the circle is: %f", area);
}
(6) (b) Write a program that read radius of a circle and display its area.
#include
<stdio.h>
#define pi 3.1416
void main ()
{
float r, area;
printf("Enter
the radius : ");
scanf("%f",
&r);
area = pi*r*r;
printf("The
area of the circle is: %f", area);
}
(6) (c) Write a program that read radius of a circle and display its area
#include
<stdio.h>
#define pi
3.1416
void main ()
{
float r, area;
printf("Enter
the radius : ");
scanf("%f",
&r);
area = pi*r*r;
printf("The
area of the circle is: %f", area);
}
7) Write a program to demonstrate the working of increment and decrement operators.
#include <stdio.h>
int main()
{
int a, c;
float b, d;
printf("a
= ");
scanf("%d",
&a);
printf("b
= ");
scanf("%f",
&b);
printf("c
= ");
scanf("%d",
&c);
printf("d
= ");
scanf("%f",
&d);
printf("++a
= %d \n", ++a);
printf("--b
= %f \n", --b);
printf("++c
= %d \n", ++c);
printf("--d
= %f \n", --d);
return 0;
}
