Conditional Statement

Consider the following ANSI C program.

 #include < stdio.h >
int main()
{
    int i, j, count;
    count=0;
    i=0;
    for (j=-3; j < =3; j++)
    {
        if (( j > = 0) && (i++))
        count = count + j;
    }
    count = count +i;
    printf("%d", count);
    return 0;
}

Which one of the following options is correct?

What is the output of tho following program?

 main(){
    int x=2, y=5;
    if(x < y) return (x=x+y);
    else printf("z1");
    printf("z2");
}

Assume A and B are non-zero positive integers. The following code segment:

 while(A!=B){
    if(A > B)
    A -= B;
    else
    B -= A;
}
cout << A; // printing the value of A

What will be the output of the following C code?

 #include < stdio.h >
main()
{
    int i;
    for(i=0;i<5;i++)
    {
        int i=10;
        printf("%d" , i);
        i++;
    }
    return 0;
}

Consider the following segment of C-code:

int j, n;
j = 1;
while (j <= n)
    j = j * 2;

The number of comparisons made in the execution of the loop for any n>0 is:
