Assume that an int variable age has been declared and already given a value. Assume further that the user has just been presented with the following menu:
S: hangar steak, red potatoes, asparagus
T: whole trout, long rice, brussel sprouts
B: cheddar cheeseburger, steak fries, cole slaw
(Yes, this menu really IS a menu!)
Write some code that reads the String (S or T or B) that the user types in into a String variable choice that has already been declared and prints out a recommended accompanying drink as follows: if the value of age is 21 or lower, the recommendation is "vegetable juice" for steak, "cranberry juice" for trout, and "soda" for the burger. Otherwise, the recommendations are "cabernet", "chardonnay", and "IPA" for steak, trout, and burger respectively. Regardless of the value of age, your code should print "invalid menu selection" if the character read into choice was not S or T or B.
ASSUME the availability of a variable, stdin, that references a Scanner object associated with standard input.
Instructor Notes:
Hint:
Use .equals for String comparison, e.g.
if (choice.equals("B")) instead of
if (choice == "B") // BAD
You might want to skip this one and do section 3.6 (which covers String comparison) beforehand.
Using the knowledge of computational language in C++ it is possible to write a code that assume that an int variable age has been declared and already given a value
Writting the code:#include<stdio.h>
#include<conio.h>
int main()
{
//variables to rad choice and age
char choice;
int age;
//read age and choice
printf("\tEnter your age: ");
scanf("%d", &age);
//fflush the keyboard buffer before reading choice
fflush(stdin);
printf("\tEnter your choice: ");
scanf("%c", &choice);
//print the invalid message if the choice is otherthan the S,T,B
if(choice!='S' && choice !='T' && choice !='B')
{
printf("Invalid menu choice");
getch();
}
else if (age <22)
{
if (choice =='S')
{
printf("\tvegetable juice");
}
else if (choice =='T')
{
printf("\tcranberry juice");

Enter a formula in cell M7 using the VLOOKUP function to find an exact match for the department abbreviation. Look up the department abbreviation (cell M6) using an absolute reference, search the staff table data (the range A6:J13) using an absolute reference, and return the department name (the 2nd column).
The VLOOKUP function is used in the calculation in cell M7 to get a precise match for the department's abbreviation.
What is VLOOKUP function?Vertical Lookup is referred to as VLOOKUP. It is a function that instructs Excel to look in a column (the so-called "table array") for a specific value in order to retrieve a value from another column in the same row.
Search the staff table data (the range A6:J13) using an absolute reference, find the department abbreviation (cell M6), and then return the department name (the second column):
M7 = VLOOKUP($M6, $A6, $J13, 2, FALSE)
As inputs, VLOOKUP accepts:
1. The value to match - in this case, we're using an absolute reference for cell M6.
2. The table array range where the value should be found - in this case, we use an absolute reference for the staff table (the range A6:J13)
The column value that will be returned in this case is the department name (2nd column)
Exact match is used in this case rather than an approximate match (FALSE)
The first column of the table's first row, A6:J13, contains the precise value in cell M6 of the VLOOKUP search, which returns the second column value for the matched row and stores it in cell M7.
