OPERATORS OF C LANGUAGE

3. Questions for Previous
Knowledge:
• What is an input?
• What is meant by output?
• What is a computer program?

4. OPERATORS OF C LANGUAGE
• Expressions consist of constants and
variables combined together with
operators. An operator is a symbol used to
command the computer to perform a
certain mathematical or logical operation.
Operators are used to operate on data and
variables.
•

5. Types of operators
• The following types of operators are
commonly used in C language.
• Arithmetic operators
• Assignment operators
• Relational operators
• Logical operators
• Increment and decrement operators

6. ARITHMETIC OPERATORS
• Arithmetic operators are used to perform
arithmetic operations that include
addition, subtraction, multiplication,
division and also to find the remainder
obtained when an integer is divided by
another integer.

7. TYPES OF ARITHMETIC OPERATORS

8. Activity

• float a,c,d,e,f;
• a=14.84;
• b=7;
• c=a-b;
• printf(“nc=%f”,c);
• d=a/b;
• printf(“nd=%f”,d);
• e=a-b*3;
• printf(“ne=%f”,e);
• f=(a+b)/2;
• printf(“nf=%f”,f);

13. Activity (Assessment 2)
