C - Variables and Data Types

You want to declare and initialize three variables a, b, and c with values 1, 2, and 3 respectively in one line. Which is the correct C statement?

Aint a, b, c = 1, 2, 3;

Bint a = 1, b = 2, c = 3;

Cint a = 1; int b = 2; int c = 3;

Dint a = 1; b = 2; c = 3;

Step-by-Step Solution

Solution:

Step 1: Understand multiple declarations with initialization
In C, you can declare multiple variables of the same type in one line by separating them with commas, and initialize each with =.
Step 2: Analyze each option
int a = 1, b = 2, c = 3; correctly declares and initializes all three variables in one statement. int a, b, c = 1, 2, 3; is invalid syntax. int a = 1; int b = 2; int c = 3; uses multiple statements, not one line. int a = 1; b = 2; c = 3; is invalid because b and c are not declared.
Final Answer:
int a = 1, b = 2, c = 3; -> Option B
Quick Check:
Use commas to declare and initialize multiple variables in one line [OK]

Quick Trick: Use commas to declare and initialize multiple variables [OK]
