Concept explainers
Type in and run the nine programs presented in this chapter. Compare the output produced by each
![Check Mark](/static/check-mark.png)
“for” condition:
The “for” condition is used to repeat the particular block until some end condition is met.
Syntax:
for (init; condition; increment)
{
//statement
}
Here, “init” is allow the user to declare and initialize any loop control variables. The “condition” is evaluated and “increment” is used to increment the values of the variable.
Explanation of Solution
Program:
Consider the five programs presented in the given chapter.
Program 4.1:
The following program will calculate the eighth triangular number:
//include the header file
#include <stdio.h>
//definition of main method
int main (void)
{
/*declare a variable*/
int triangularNumber;
//calculate the "triangularNumber"
triangularNumber = 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8;
//display the result
printf ("The eighth triangular number is %i\n", triangularNumber);
//return statement
return 0;
}
Explanation:
In the above program, declare the variable and calculate the eighth triangular number. Then display the values using “printf” function on the output screen.
Sample Output for program 4.1:
The eighth triangular number is 36

Define and use a new function, isEven, that returns a Boolean to make the condition in the if statement easier to understand. ef main() : page = int(input("Enter page number: ")) if page % 2 == 0 : print(page) else : print("%60d" % page) main()arrow_forwardWhat is the correct python code for the function def countWords(string) that will return a count of all the words in the string string of workds that are separated by spaces.arrow_forward
- Consider the following program that counts the number of spaces in a user-supplied string. Modify the program to define and use a function, countSpaces, instead. def main() : userInput = input("Enter a string: ") spaces = 0 for char in userInput : if char == " " : spaces = spaces + 1 print(spaces) main()arrow_forwardWhat is the python code for the function def readFloat(prompt) that displays the prompt string, followed by a space, reads a floating-point number in, and returns it. Here is a typical usage: salary = readFloat("Please enter your salary:") percentageRaise = readFloat("What percentage raise would you like?")arrow_forwardassume python does not define count method that can be applied to a string to determine the number of occurances of a character within a string. Implement the function numChars that takes a string and a character as arguments and determined and returns how many occurances of the given character occur withing the given stringarrow_forward
- Consider the ER diagram of online sales system above. Based on the diagram answer the questions below, a) Based on the ER Diagram, determine the Foreign Key in the Product Table. Just mention the name of the attribute that could be the Foreign Key. b) Mention the relationship between the Order and Customer Entities. You can use the following: 1:1, 1:M, M:1, 0:1, 1:0, M:0, 0:M c) Is there a direct relationship that exists between Store and Customer entities? Answer Yes/No? d) Which of the 4 Entities mention in the diagram can have a recursive relationship? e) If a new entity Order_Details is introduced, will it be a strong entity or weak entity?
