In the following C declarations and statements: int ram; float alpha, gamma; ram = 6400; alpha = 0.562; gamma = alpha * ram + 1; which statements are correct: (1) ram is an integer variable, (2) alpha and gamma are real (float) variables, (3) * and + are arithmetic operators, (4) 0.562 may be an integer or real constant?

Introduction / Context:
This question checks foundational C knowledge: basic data types (int, float), operators (*, +), and numeric literal classification (integer vs real/floating constants).

Given Data / Assumptions:

• Declarations: int ram; float alpha, gamma;
• Assignments: ram = 6400; alpha = 0.562; gamma = alpha * ram + 1;
• Statements to evaluate: (1) ram is an integer variable, (2) alpha and gamma are real variables, (3) * and + are arithmetic operators, (4) 0.562 may be an integer constant or real constant.

Concept / Approach:
Map each statement against C rules: types from declarations, operator categories, and literal kinds. A number with a decimal point is a floating (real) constant, not an integer constant.

Step-by-Step Solution:

Verification / Alternative check:
Compiler perspective: '0.562' tokenizes as a floating literal; integer constants have no decimal point and optional suffixes. Therefore, (4) cannot be true in C.

Why Other Options Are Wrong:

• All: Incorrect because (4) is false.
• 2, 3, 4 only: Incorrect because (4) is false and (1) is true.
• 1, 2, 4 only: Incorrect because (4) is false; (3) is true.

Common Pitfalls:

• Assuming any numeral can be either int or float; the decimal point determines a floating literal.
• Overlooking that 'float' variables are commonly called 'real' in older terminology.

Final Answer:
1, 2, 3 only
