An Introduction to Programming Through C++ NPTEL 2022 Week 1 Assignment Answers

Suppose a “rightgoing step” consists of a upward going line of length 10 followed by a rightgoing line of length 10.  The following code draws 5 rightgoing steps, i.e. a staircase.  Assuming the turtlestarts pointing in the rightward direction, and assuming the steps rise by 50 in the right fill in the blanks.
repeat(5){ blankA; blankB; blankC; blankD;}
Given below are 4 fill in the blank questions.  You have to answer by writing only the required answer without any blanks or anything, as it would appear in your program.  For example for the first question you should fill “left(90)” (without the quotes).

Suppose you decide to represent the cards in a standard deck using the numbers 1 through 52. So for this, the cards are arranged so that the clubs come first, then the diamonds, then the hearts and then the spades. Also within a suit, the order of the cards is ace, then the cards 2 through 10, then the jack, then the queen, then the king. So after arranging the cards in this manner, the ith card is assigned the number i. Thus the king of spades will get the number 52, and the ace of clubs the number 1.

Q5. What number does the 9 of spades get?

Programming Assignment 1.1

Write a program that reads in numbers m, n and prints the letter X (capital X) m times followed by the letter Y (capital Y) n times, all in one line. Don’t write the #include < simplecpp > statement at the beginning of your code, directly start the main_program

~~~THERE IS SOME INVISIBLE CODE HERE~~~

int main(){
     int m,n;
     cin>>m>>n;
 
 
     while(m--){
        cout<<"X";
     }

     while(n--){
       cout<<"Y";
     }
}

Programming Assignment 1.2

Write a program that reads in a number m and prints a ‘*’ on m consecutive lines, followed by m+1 ‘*’s on a single line.  The result should look like the letter L made out of stars. You can go to a new line in the output using cout << endl; .Don’t write the #include < simplecpp > statement at the beginning of your code, directly start the main_program

~~~THERE IS SOME INVISIBLE CODE HERE~~~

int main() {
  int m;
  cin>>m;

  int a = m;

  while(a--) {
    cout<<"*"<<endl;
  }

  int b=m+1;

  while(b--) {
    cout<<"*";
  }
