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

Operator Meaning

+ Addition or unary plus

- Subtraction or unary minus

* Multiplication

/ Division

% Modulo division

++ Increment operator increases the integer value

by one.

-- Decrement operator decreases the integer

value by one.

Arithmetic expressions: An arithmetic expression is a combination of variables, constants, and

operators.

For example,

Arithmetic expressions: niterians.blogspot.com

a*b-c a*b-c

(m+n)(x+y) (m+n)*(x+y)

ax2+bx+c a*x*x+b*x+c

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);

}

{

float a, b, c;


scanf("%f", &a);


scanf("%f", &b);

c =a+b;

printf("Sum of a and b is %f ", c);

}

#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);

}
