Study Notes
Relational Operators
- Relational operators help compare data
- Used to make decisions in a computer program
- Examples of relational operators are: greater than, less than, equal, not equal
- Used in "if-else" statements
Conditional Statements
- Used to control the flow of a program based on conditions
- Used in combination with relational operators
- "If" statements execute code if a condition is true
- "Else" statements execute code if a condition is false
- Statements can be combined (if-else-if) for multiple conditions
Flowcharting Conditional Statements
- Flowcharting uses graphical symbols to visualize program flow
- Symbols for Start/End, Variable declaration, Input/Output
- Example: flowchart for finding the sum of two numbers
Logical Operators
- Combine conditional statements
- Examples of logical operators are: AND, OR
- These operators determine the truth value of a compound statement
- C language uses && for AND and || for OR
- Example: check if a student has passed an exam with multiple conditions
Example Problem
- Input name, marks in three subjects, check if student passed the exam
- Use logical operators to combine conditions: individual marks >= 35, AND average >= 40.
The Equation
- The equation Y = ( ((5x + 3 ) x + 2 )* x + 1)* x + 10 can be rewritten without powers of x by expanding the expression
- This can be done by performing each multiplication step in a nested fashion.
- The result will be a polynomial expression in x.
