The document covers decision-making in programming using equality and relational operators, focusing on their syntax and usage in if statements. It includes examples of conditions to evaluate student grades and compares integers with various mathematical operations. The document also warns about common syntax errors associated with these operators.

- 2. What is the decision ? Equality and relational operators. Precedence and associatively of operations How to use if ? Practice Be care Emank X Mezank 2Presented & Prepared by: Mahmoud R. Alfarra
- 3. For example, the condition "grade is greater than or equal to 60" determines whether a student passed a test. 3Presented & Prepared by: Mahmoud R. Alfarra What is the decision ? Note 5 applications demand the making decision HW 5.1
- 4. Conditions in if statements can be formed by using the equality operators and relational operators. Equality operators are used to check if two operands are equals or not. Relational operators are used to check if one of two operands are greater or less than another. 4Presented & Prepared by: Mahmoud R. Alfarra Equality and relational operators

- 8. Write a program to compare two numbers and print the larger, smaller, equal or not. 8Presented & Prepared by: Mahmoud R. Alfarra Example: Compare Integers Write a program to calculate the summation, multiple, division, subtraction and then compare the results to print the larger, smaller, equal or notHW 5.2
- 9. 9Presented & Prepared by: Mahmoud R. Alfarra Example: Compare Integers Rewrite this program using another values HW 5.3
- 10. 10Presented & Prepared by: Mahmoud R. Alfarra Forgetting the left and/or right parentheses for the condition in an if statement is a syntax error the parentheses are required. Confusing the equality operator, ==, with the assignment operator, =, can cause a logic error or a syntax error. It is a syntax error if the operators ==, !=, >= and <= contain spaces between their symbols, as in = =, ! =, > = and < =, respectively. Reversing the operators !=, >= and <=, as in =!, => and =<, is a syntax error.
