data work.quiz2; set work.quiz; drop B D; E=sum (A, B, C, D); D-mean (A, B); run; The SAS table work.quiz has four columns, which are numeric and named A, B, C, and D. After I run the code shown above, how many columns will be in work.quiz2?

What is the return value of “ corona”. Substring(0,3)

What transpires when a parameter for an array is sent in with either the ref or out keyword, and the results are observed?

Must be written in the coral language. Complete the PrintArray function to iterate over each element in dataValues. Each iteration should put the element to output. Then, put "*" to output. Ex: If dataValue's elements are 2 4 7, then output is: 2*4*7*

For any element in keysList with a value greater than 50, print the corresponding value in itemsList, followed by a comma (no spaces). Ex: If the input is: 32 105 101 35 10 20 30 40 the output is: 20,30, 1 #include 2 3 int main(void) { const int SIZE_LIST = 4; int keysList[SIZE_LIST]; int itemsList[SIZE_LIST]; int i; 4 6 7 8 scanf("%d", &keysList[0]); scanf ("%d", &keysList[1]); scanf("%d", &keysList[2]); scanf("%d", &keysList[3]); 10 11 12 13 scanf ("%d", &itemsList[0]); scanf ("%d", &itemsList[1]); scanf("%d", &itemsList[2]); scanf ("%d", &itemsList[3]); 14 15 16 17 18 19 /* Your code goes here */ 20 21 printf("\n"); 22 23 return 0; 24 }

Consider the set A = {1, 2, 11, {121}, 22, 1212, (111, 212, 112}} Enter the value of Al. (Note: Enter a number).

int pid1 = fork(); int pid2 = fork(); printf("PID: %d %d\n", pid1, pid2);   Output with explanation

show: Lists the items that the wizard is currently carrying along with the index for each item and the weight of that item. See sample runs below. As shown in the sample this function also prints the total weight of the items along with the max weight limit of 100 lbs. Hint: You can use the sum function in Python to calculate the sum of weights. E.g. sum(weights) will return the sum of all the items in the weights list. grab_item: Add a new item while enforcing the following policy: There is a limit of 4 on the number of items the wizard can carry and limit of 100 lbs on the total weight the wizard can carry. So specifically, if the wizard is already carrying 4 items, print message that “You can't carry anymore items. Drop something first.” And return out of the function. Otherwise prompt the user for the name and the weight of the new item. Next check whether with the addition of the new item, the total weight will exceed the limit of 100 lbs. If so, print a message saying weight…

The below cod is the code that it’s mentioned in the question. Write your cod and show it in a picture, please.

In C#: Run the following console application. This program should produce the union of two sets, but has several errors. Use a variety of debugging techniques to locate and correct the errors.  NOTE: A set is a collection of like elements that does not contain any duplicates. The union of two sets is the set that contains all the elements in both sets. Formally: A union B = {x : x Î A or x Î B}read: A union B is the set of all x such that x is in A or x is in B Example: A = {1,2,3,4,5} and B = {2,4,6,8}, then A union B = {1,2,3,4,5,6,8} (notice, no duplicates!) Debug the program. When you find an error, comment out the offending line, give an explanation of the error, write a corrected line, and include a screenshot of your program running with successful output. Submit the modified files and screenshots of any breakpoints you use.
