Question

Given the following C++ code snippet, what is the value of num3? Your answer must be exact.
int num1, num2, num3;
int "p_num1
int "p_num2 - &num2;
&num1;
"P_num1
15;
"P_num2 -
123;
num3 - "p_num1 + "P_num2;

Expert Solution

Step 1

Here *p_num1 and *p_num2 are pointers to num1 and num2.

Thus when we say *p_num1=15, we are trying to change the content of num1 ie referencing num1.

What Kinds Of Operations Can Typically Be Carried Out On A Data Structure?
T The information in DNA is stored as a code made up of four chemical bases which are represented by four upper case letters A, T, G, C. An example DNA sequence could be: ATGAG An interesting phenomena here is that when two DNA sequences are attempted to combine, A can only pair with T whereas G can only pair with C. Two DNA sequences for example ATGC and TACG are considered 'fully complementary' because the bases (letters) in every index position can be paired to each other (see the image). ATGC ATGC ATGC XX TACG Fully Complementary TACC SNP TTCA CA Non Complementary Two DNA sequences for example ATGC and TACC are considered 'SNP type' because there is exactly one index position (last position in this case) in which the bases(letters) can not be paired. Two DNA sequences for example ATGC and TTCA are considered "non complementary' because there are more than one index position (second and fourth in this case) in which the bases can not be paired.
