C - onditional Statements

Which of the following is the correct syntax for a nested if statement in C?

if (x > 0) {
    if (y < 10) {
        // code
    }
}

Aif x > 0 { if (y < 10) { /* code */ } }

Bif (x > 0) if (y < 10) { /* code */ }

Cif (x > 0) { if y < 10 { /* code */ } }

Dif (x > 0) { if (y < 10) { /* code */ } }

Step-by-Step Solution

Solution:

Step 1: Check correct use of braces and parentheses
In C, conditions must be inside parentheses and blocks inside braces. if (x > 0) { if (y < 10) { /* code */ } } uses both correctly.
Step 2: Identify syntax errors in other options
if (x > 0) if (y < 10) { /* code */ } misses braces for outer if block. if (x > 0) { if y < 10 { /* code */ } } misses parentheses around y < 10. if x > 0 { if (y < 10) { /* code */ } } misses parentheses around x > 0.
Final Answer:
if (x > 0) { if (y < 10) { /* code */ } } -> Option D
Quick Check:
Correct syntax = if (x > 0) { if (y < 10) { /* code */ } } [OK]

Quick Trick: Use parentheses for conditions and braces for blocks [OK]
