Which programming language represents data in the form of a series of 0s and 1s?

Can you help me with these AP Computer Science Questions. (THIS IS DUE BY 1:30 PM today) you have to evaluate the Boolean Expres

vfiekz [6]

Answer + Explanation:

'and' -> both statements are 'True' to evaluate as 'True'.

'or' -> at least one statement is 'True' to evaluate as 'True'.

1. True (grade has the value of 82, so the statement evaluates to 'True').

2. True (Both statements are true, this expression evaluates to 'True').

3. False (Both statements are false, this expression evaluates to 'False').

4. True (the != operator means not equal. Since the 'name' variable holds the string 'Rumpelstiltskin', name != 'Rumpelstiltskin' evaluates to 'False'. The 'not' operator returns the opposite of the given Boolean expression, so this expression evaluates to 'True').

5. True (name == 'Rumpelstiltskin' evaluates to 'True', so this expression is true).

6. False (All statements evaluate to 'False').

7. True (All statements evaluate to 'True').

8. False (All statements evaluate to 'True' except for not(x == - 3) which evaluates to 'False', so the whole statement now becomes false).

9. True (grade+5 < 90 and grade >= 80 evaluates to 'True', so this whole expression becomes true).

10. True (grade > 0 and x % 2 == 1 evaluates to 'True')

Hope this helps :)

Mix ‘em Let s1 and s2 be 2 c-strings of the same length. Write a function char* mixem(char*s1, char* s2) which returns a c-strin

Shkiper50 [21]

Answer:

See Explaination

Explanation:

#include <iostream>

#include <string.h>

using namespace std;

char *mixem(char *s1, char *s2);

int main() {

cout << mixem("abc", "123") << endl;

cout << mixem("def", "456") << endl;

return 0;

}

char *mixem(char *s1, char *s2) {

char *result = new char[1 + strlen(s1) + strlen(s2)];

char *p1 = s1;

char *p2 = s2;

char *p = result;

while (*p1 || *p2) {

if (*p1) {

*p = *p1;

p1++;

p++;

}

if (*p2) {

*p = *p2;

p2++;

p++;

}

*p = '\0';

return result;

}

The ____ algorithm tries to extend a partial solution toward completion

Fittoniya [83]

Answer: Backtracking

Explanation:

Backtracking algorithm approaches a solution in a recursive fashion whereby it tries to build answers and modify them in time intervals as we progress through the solution. One such backtracking algorithm is the N Queen problem whereby we place N Queen in a chessboard of size NxN such that no two queens attack each other. So we place a queen and backtrack if there is a possibility that the queen is under attack from other queen. This process continues with time and thereby it tends to extend a partial solution towards the completion.

When a program lets the user know that an invalid input choice has been made, this is known as _________________.

Leto [7]

Answer:

The correct answer for the given question is " input validation"

Explanation:

Input validation is also known as data validation which is used for validate or test the user input .

The example of input validation in c++ programming

#include <iostream> // header file

using namespace std;

int main() // main function

{

int a1; // variable declarartiomn

cout << "Enter the age: ";

cin >> a1;

if(a1> 18) // validate user input

{

cout << "You are eligible for vote :";

}

return 0;

}

In this program we input a age from user and validate this user input that .If user enter age > 18 then it will eligible for vote.

output

21

You are eligible for vote
