在运行中，它显示答案是错还是对，但即使它是错的，它仍然会被添加到正确答案的数量。我该怎么做或添加使它工作？

#include<stdio.h>

int main(void) {
    char choice;
    int correctAnswer = 0, wrongAnswer = 0;

    printf("Who developed C?\n");
    printf("A. Dennis Leary \tC. Dennis Rodman\nB. Dennis Ritchie \tD. Dennis Ruth");
    printf("\nAnswer: ");
    scanf("%c", &choice);

    switch (choice)
    {
    case 'A':
        printf("Wrong Answer.\n");
        break;
    case 'B':
        printf("Correct Answer.\n");
        break;
    case 'C':
        printf("Wrong Answer.\n");
        break;
    case 'D':
        printf("Wrong Answer.\n");
        break;
    default:
        printf("Invalid Answer\n");
        
    }
    if ('B')
        correctAnswer++;
    else
        wrongAnswer++;
    
    printf("Number of Correct Answers: %d\n", correctAnswer++);
    printf("Number of Wrong Answers: %d\n", wrongAnswer++);
}```

I expect the code to add the wrong answers to be added in the Number of Wrong Answers and it seems it recognized all answers as a correct answer.
