    The first program prints "j = 11" as i is incremented to 11 before assigning to j. The second prints "1" as number 31 % 2 is 1. // are used for single-line comments in C. The third program prints "Quiz" as case statements evaluate expressions left to right. The fourth prints "3" as printf returns a non-zero value so the if statement executes.

    C Choice A
    Choice B
    No choice
    D Program gives no output as it is erroneous
    #include<stdio.h>
