C - Variables and Data Types

Which of the following correctly declares and initializes three integer variables x, y, and z with values 7, 8, and 9 respectively in a single statement?

Aint x = 7; int y = 8; int z = 9;

Bint x, y, z = 7, 8, 9;

Cint x = 7, y = 8, z = 9;

Dint x = 7; y = 8; z = 9;

Step-by-Step Solution

Solution:

Step 1: Understand multiple declarations
In C, multiple variables can be declared and initialized in one statement separated by commas.
Step 2: Analyze options
int x = 7, y = 8, z = 9; correctly declares and initializes all three variables in one line.
Step 3: Identify incorrect options
int x, y, z = 7, 8, 9; is invalid syntax; int x = 7; int y = 8; int z = 9; uses multiple statements, not one; int x = 7; y = 8; z = 9; misses type for y and z.
Final Answer:
int x = 7, y = 8, z = 9; -> Option C
Quick Check:
Multiple variables can be declared with commas in one statement [OK]

Quick Trick: Use commas to declare multiple variables in one line [OK]

Common Mistakes:

Trying to assign multiple values without commas
Omitting type for subsequent variables
Using multiple statements instead of one
