Correct!
In order to determine which expressions produce a value of type int, we need to consider the data types and operators used in each expression. Here are the possible expressions:
1. 5 + 3
2. 5 - 3
3. 5 * 3
4. 5 / 3
5. 5 % 3
6. 5.0 + 3
7. 5 / 3.0
Let's analyze each expression:
1. 5 + 3:
This expression uses the '+' operator to perform addition between two integers, resulting in an integer value. Therefore, this expression produces a value of type int.
2. 5 - 3:
This expression uses the '-' operator to perform subtraction between two integers, resulting in an integer value. Therefore, this expression produces a value of type int.
3. 5 * 3:
This expression uses the '*' operator to perform multiplication between two integers, resulting in an integer value. Therefore, this expression produces a value of type int.
4. 5 / 3:
This expression uses the '/' operator to perform division between two integers. However, since both operands are integers, the division operation performs integer division, which truncates the decimal part. Therefore, this expression produces a value of type int.
5. 5 % 3:
This expression uses the '%' operator to find the remainder of the division between two integers. The result of the modulus operator is always an integer. Therefore, this expression produces a value of type int.
6. 5.0 + 3:
This expression involves a floating-point number ('5.0') and an integer ('3'). When adding a floating-point number and an integer, the result will be a floating-point number. Therefore, this expression does not produce a value of type int.
7. 5 / 3.0:
This expression involves an integer ('5') and a floating-point number ('3.0'). Similar to the previous case, when dividing an integer by a floating-point number, the result is a floating-point number. Therefore, this expression does not produce a value of type int.
Based on the analysis above, the expressions that produce a value of type int are:
1. 5 + 3
2. 5 - 3
3. 5 * 3
4. 5 / 3
5. 5 % 3
