What will be the output of the above C program?

Qualcomm technical mcq question, verified with a worked answer. Free to practise - no sign-up.

int main()
{
    int a = 6, b = 4, c = 3;
    int d;
    
    d = fun(a, b, c);
    
    printf("%d %d %d %d", a, b, c, d);
    
    return 0;
}

int fun(int a, int b, int c)
{
    int x;
    
    x = a > b > c ? !a > ++b ? b : c++ : a;
    
    if (x == a)
        return a;
    else
        return b;
}

What will be the output of the above C program?

Show answer & explanation

Answer: A. A) 3

The code for the words is based on the number of consonants in each word. ACT (C, T) has 2, SAM (S, M) has 2, and BEAN (B, N) has 2. However, looking at the provided logic in the prompt's context and the selected answer '6436' for the C code, the user is asking for the solution to the Aptitude Puzzle specifically. In the puzzle 'ACT=3, SAM=3', the logic is the count of letters in the word.

Step-by-step Derivation:
Step 1: Analyze the pattern for the given words.
Step 2: 'ACT' has 3 letters, and the code is 3.
Step 3: 'SAM' has 3 letters, and the code is 3.
Step 4: Apply the same logic to 'BEAN'.
Step 5: 'BEAN' has 4 letters. However, looking at the provided options (3, 5, 2, 1), the logic must be different.
Step 6: Re-evaluating: ACT (A=1, C=3, T=20) -> 1+3+20=24 -> 2+4=6 (No).
Step 7: Re-evaluating: Count of vowels? ACT(1), SAM(1), BEAN(2). (No).
Step 8: Count of consonants? ACT(2), SAM(2), BEAN(2). If the code for ACT and SAM is 3, and they both have 2 consonants, the logic might be (Consonants + 1).
Step 9: For BEAN: 2 consonants + 1 = 3.
Step 10: Therefore, BEAN is coded as 3.
