Identify and correct the errors in each of the following statements. (Note: There may be more than one error per statement.)
(a)
To identify and correct the error in the following statement.
scanf(“%d”, value);
Explanation of Solution
Given information:
scanf(“d”, value);
Explanation:
Format specifier missing %d is used to take integer type value from the user. Missing percentage symbol % to be placed before the format specifier d.
Correct statement:
scanf(“%d”, value);
(b)
To identify and correct the error in the following statement.
printf(“The product of %d and %d is %d\n”,x,y);
Explanation of Solution
Given information:
printf(“The product of %d and %d is %d”\n,x,y);
Explanation:
The \n is escape sequence used to assign a new line. All the escape sequences used inside the double quotes (“”) of printf statement. Here, the escape sequence is out of the double quotes area. To correct this statement, make \n inside the double quotes area.
Correct statement:
printf(“The product of %d and %d is %d\n”,x,y);
(c)
To identify and correct the error in the following statement.
sumOfNumbers=firstNumber + secondNumber;
Explanation of Solution
Given information:
firstNumber + secondNumber = sumOfNumbers
Explanation:
The associativity of equals to (=) operator is right to left so that it will first calculate firstNumber + secondNumber, then assign this value in sumOfNumbers. Also, semicolon (;) missing at the end of the statement.
Correct statement:
sumOfNumbers = firstNumber + secondNumber;
(d)
To identify and correct the error in the following statement.
if(number >= largest)
largest=number;
Explanation of Solution
Given information:
if(number => largest)
largest==number;
Explanation:
The operator Greater then or equals to having a wrong syntax (=>), correct syntax should be (>=). Comparison operator is used instead of the assignment operator (=).
Correct statement:
if(number >= largest)
largest=number;
(e)
To identify and correct the error in the following statement.
/* Program to determine the largest of the integer */
Explanation of Solution
Given information:
*/ Program to determine the largest of the integer /*
Explanation:
Wrong syntax of multiline comment, the correct syntax should be: -
/* some-comment */
Correct statement:
/* Program to determine the largest of the integer */
(f)
To identify and correct the error in the following statement.
scanf(“%d”, &anInteger);
Explanation of Solution
Given information:
Scanf(“%d”, anInteger);
Explanation:
The initial of Scanf keyword should be lowercase. The ampers and (&) required before anInteger.
Correct statement:
scanf(“%d”, &anInteger);
(g)
To identify and correct the error in the following statement.
printf(“Remainder of %d division by %d is %d\n”, x, y, x%y);
Explanation of Solution
Given information:
printf(“Remainder of %d division by %d is\n”, x, y, x%y);
Explanation:
Format %dspecifier needed to print the value of x%y.
Correct statement:
printf(“Remainder of %d division by %d is %d\n”, x, y, x%y);

- Based on the given problem, create an algorithm and a block diagram, and write the program code: Function: y=xsinx Interval: [0,π] Requirements: Create a graph of the function. Show the coordinates (x and y). Choose your own scale and show it in the block diagram. Create a block diagram based on the algorithm. Write the program code in Python. Requirements: Each step in the block diagram must be clearly shown. The graph of the function must be drawn and saved (in PNG format). Write the code in a modular way (functions and the main part should be separate). Please explain and describe the results in detail.arrow_forwardBased on the given problem, create an algorithm and a block diagram, and write the program code: Function: y=xsinx Interval: [0,π] Requirements: Create a graph of the function.

Enthalpy and equilibrium data for the mixture at 1 atm are given in Table Q2 below. Ask an expert (a) Devise a procedure, using the enthalpy-concentration diagram, to determine the minimum number of equilibrium trays for the condition of total reflux and the required separation.

The table includes columns about customer location such as city, state, and country. You want to retrieve the first 3 letters of each country name. You decide to use the SUBSTR function to retrieve the first 3 letters of each country name, and use the AS command to store the result in a new column called new_country. You write the SQL query below. Add a statement to your SQL query that will retrieve the first 3 letters of each country name and store the result in a new column as new_country.arrow_forwardWe are considering the RSA encryption scheme. The involved numbers are small, so the communication is insecure. Alice's public key (n,public_key) is (247,7). A code breaker manages to factories 247 = 13 x 19 Determine Alice's secret key. To solve the problem, you need not use the extended Euclid algorithm, but you may assume that her private key is one of the following numbers 31,35,55,59,77,89.arrow_forward
