C - Loops

Which of the following correctly demonstrates a nested while loop structure in C?

Awhile(i < 3) { while(j < 2) { /* code */ } }

Bwhile(i < 3); while(j < 2) { /* code */ }

Cwhile(i < 3) { j < 2; /* code */ }

Dwhile(i < 3) { while(j < 2); /* code */ }

Step-by-Step Solution

Solution:

Step 1: Understand nested loops
A nested loop means one loop inside another, both properly structured.
Step 2: Analyze options
while(i < 3) { while(j < 2) { /* code */ } } correctly nests one while loop inside another with braces.
Step 3: Identify incorrect syntax
Options B, C, and D misuse semicolons or lack proper braces, breaking the loop structure.
Final Answer:
while(i < 3) { while(j < 2) { /* code */ } } -> Option A
Quick Check:
Proper nesting requires braces and no stray semicolons [OK]
