345154.2174782.qx3zqy7 Jump to level 1 Define a function ParseStr() that takes a string parameter and returns "Yes" if the character at index 5 in the string parameter is uppercase. Otherwise, the function returns "No". Ex: ParseStr("SWIMMING") returns Yes Recall isupper() checks if the character passed is uppercase. Ex: isupper( 'A') returns a non-zero value. isupper ('a') returns 0. string's at() returns a character at the specified position in the string. Ex: myString.at(3) 1 #include 2 #include 3 #include 4 using namespace std; 5 6 int main() { string input; string output; 8 9. getline(cin, input); output cout << output << endl; 10 11 ParseStr(input); %3D 12 13 14 return 0; 15 } 3. 2 1
Define function print_popcorn_time() with parameter bag_ounces. If bag_ounces is less than 3, print "Too small". If greater than 10, print "Too large". Otherwise, compute and print 6 * bag_ounces followed by "seconds". End with a newline. Remember that print() automatically adds a newline. Sample output with input: 7 42 seconds
Consider the following code def f(a, b): if a > 3: return a, b-a return a+b, b you can call the above function as Select one: a. x1,x2,x3,x4=f(10,20) b. x1,x2,x3=f(10,20) c. x1=f(10,20) d. x1,x2=f(10,20)

Playing with Functions: Write a Javascript program to check if the argument passed to any function is a function type or not. I.e. Create a function check which takes a argument and check if that argument is a function or not.
In C language / Please don't use (sprint) function. Write a function fact_calc that takes a string output argument and an integer input argument n and returns a string showing the calculation of n!. For example, if the value supplied for n were 6, the string returned would be 6! 5 6 3 5 3 4 3 3 3 2 3 1 5 720 Write a program that repeatedly prompts the user for an integer between 0 and 9, calls fact_calc and outputs the resulting string. If the user inputs an invalid value, the program should display an error message and re-prompt for valid input. Input of the sentinel -1 should cause the input loop to exit. Note: Don't print factorial of -1, or any number that is not between 0 and 9.

Add a function to get the CPI values from the user and validate that they are greater than 0. 1. Declare and implement a void function called getCPIValues that takes two float reference parameters for the old_cpi and new_cpi. 2. Move the code that reads in the old_cpi and new_cpi into this function. 3. Add a do-while loop that validates the input, making sure that the old_cpi and new_cpi are valid values. + if there is an input error, print "Error: CPI values must be greater than 0." and try to get data again. 4. Replace the code that was moved with a call to this new function. - Add an array to accumulate the computed inflation rates 1. Declare a constant called MAX_RATES and set it to 20. 2. Declare an array of double values having size MAX_RATES that will be used to accumulate the computed inflation rates. 3. Add code to main that inserts the computed inflation rate into the next position in the array. 4. Be careful to make sure the program does not overflow the array. - Add a…

We want to develop a game where the user should guess a secret number. The game asks the user to input a number and tells how close it is to the secret random number that the game generates. Complete the main() function that implements this game by calling the get_user_input(), generate_secret(), and display_result(user_input, secret) functions that you will develop as follows: • Complete the get_user_input() function so that it prompts the user to enter a whole number between 1 and 20 (inclusive) and returns the number that the user enters. • Complete the generate_secret() function so that it generates and returns a random number between 1 and 20 (inclusive). Complete the display_result(user_input, secret) function that takes the two parameters that correspond to the user input and the secret. It should then print the absolute difference between these two numbers. For example: Test Input Result random.seed (10) 5 random.seed(50) 6 Enter a number from 1 to 2015 You entered 5. The…
