C - Loops

Which of the following code snippets correctly demonstrates a do-while loop in C that prints numbers from 1 to 3?

Aint i = 1; do { printf("%d ", i); i++; } while (i <= 3);

Bint i = 1; while (i <= 3) { printf("%d ", i); i++; }

Cint i = 1; do { printf("%d ", i); i++; } while i <= 3;

Dint i = 1; do { printf("%d ", i); i++; } while i < 3;

Step-by-Step Solution

Solution:

Step 1: Identify the correct syntax for a do-while loop
The do-while loop syntax requires the condition to be inside parentheses and followed by a semicolon.
Step 2: Check each option
int i = 1; do { printf("%d ", i); i++; } while (i <= 3); uses the correct syntax: do { ... } while (condition);. int i = 1; while (i <= 3) { printf("%d ", i); i++; } is a while loop, not do-while. int i = 1; do { printf("%d ", i); i++; } while i <= 3; and D miss parentheses around the condition, which is a syntax error.
Final Answer:
int i = 1; do { printf("%d ", i); i++; } while (i <= 3); is the correct syntax.
Quick Check:
Condition must be in parentheses and end with a semicolon [OK]

Quick Trick: Condition in do-while must be in parentheses and end with semicolon [OK]
