Write C Program Fixes List Bank Card Numbers Miss One Digits Restore Digit Others Pair Adj Q43794613
Write a c++ program that fixes a list of bank card numbers. Someof them just miss one of digits and you should restore this digit.Others have a pair of adjacent digits swapped – you are to find theleftmost pair which, if swapped, makes valid cardnumber.
All the card numbers would be 16 digits long.
Input data contain a list of workers who havetheir card numbers incorrect.
Next lines contain a single card number each. If the numbercontains “?” (question mark) instead of some digit – this digitshould be restored. If all digits are present, then “swap-error”should be fixed.
Answer should contain a list of “fixed” cardnumbers.
input data:

______________________________________________________________________________________
I need some help with my program. It is able to find a value toreplace the “?” with, but it does not find the right value for allof the test cases above. I also wrote a function(not included inbelow code), which use if statement to branch when the string doesnot contain “?” and deal with swap errors. For that, my approachwas to swap adjacent values, but I was able to get the right valueoutput to match the output sample above. I believe a map would behelpful to deal with this program, but I am not familiar with mapas data structures. I would appreciate your input. Since this is myfirst time trying to work with map, I would appreciate commentsinside the code. Also, I use Luhn Algorithm to check if a card isvalid or not.

Write C Program Gradec Includes Function Calculateaverage Calculate Average Arbitrary Numb Q43826010
write a C program, grade.c, which includes a function,
calculateAverage(), that can calculate the average ofan arbitrary number of test scores.
your program will not know in advance how many test scores willbe entered into your function
so you will need to use a sentinel value (-1) to terminate thewhile loop used to collect the test scores.
the test scores are integers in the range 0 to 100 and the testscore average should be output to two decimal places.
be sure that the user prompts and grades input into the programare displayed in the output file.
provided below is the main() function that I would likeyou to use for your program:
int main (void){
int I;
fopen_s(&fp, “csis.txt”, “w”);
for (i = 1; i <= 4; ++i) {
calculateAverage();
}
fclose(fp);
return 0;
}
please do not modify the main() function. it shouldappear as the first function in the program.
Be sure to use function prototypes for each of the functionsthat are used in your program.
Note that the first for loop invokes thecalculateAverage() function four times.
Each time the calculateAverage() function is invoked, adifferent set of test grades will be entered.
Please be sure to use the data shown below.
First: 78, 93, 45, 88, 89, -1
second: 87, 68, 100, -1
third: 84, 86, 90, 86, 96, 68, 82, -1
fourth: -1
Be sure that your code does not attempt to divide by zero forthe fourth run of the program.

Write C Program Inputs Contents File Line Line Outputs Line Console Program Starts Inputti Q43856576
Write a C++ program that inputs the contents of a file line byline, and outputs each line to the console. The program starts byinputting the name of the file from the keyboard, opens the file,and then checks to make sure the file was opened successfully. Ifnot, the program outputs “**file not found” and returns.
If the file was opened successfully, the program proceeds toread the file line by line, outputting each line to the consolealong with its line number. Assume each line of the input filecontains a single word. For example, suppose the file “input1.txt”contains the following:
apple
banana
pear
pizza
Given the filename “input1.txt”, your program should produce thefollowing output:
line 1: apple
line 2: banana
line 3: pear
line 4: pizza
