Passing an array name to a pointer assigns the first memory location of the array to the pointer variable?

Yes, passing an array name to a pointer assigns the first memory location of the array to the pointer variable. An array name is the same as a pointer to the first location of the array, with the exception that an array name is a r-value, while a pointer is an l-value.

How do you swap two numbers without using third one using pointers?

How do you do.

I am doing well thank you.

Swap two number by using reference operators

A tough assignment, it will make you think.

I think you are confusing reference operators with pointers.

Were I you I would study the section on pointers in your text book or course material.

What is pattern rule for pattern 26-22-7-27-15-34?

One possible rule is:

Un = (243n5 - 4210n4 + 27225n3 - 60830n2 + 106452n - 45960)/120

for n = 1, 2, 3, etc

What are ActionScript errors 1021 and 1023?

Error 1021: Duplicate Function Definition

Error 1023: Incompatible Override

The first error means you've defined the same function twice. There can be only one definition for each function.

The second means you've overridden a function but the declaration is incorrect.

In C Programming Language Can someone write a program that will interact with the user by name and allow for the recording of grades for three classes Tech History and Math?

More info;

You will write a program that will interact with the user by name and allow for the recording of grades for three classes: Tech, History, and Math. The program will allow the user to determine how many assignments to enter in each class, the name of each assignment, the total value of each assignment, and the users score on each assignment. The program will will write the scores to a file and have the ability to:

  • Tell the user the high and low score in each class along with the assignment name

  • Repeat entries back to user by assignment name and score to ensure accuracy

  • Tell the user their current grade in each class

  • Tell the user their current gpa based on the overall percentage of each class

What is procedural justice and why is it important?

Procedural justice refers to the fairness of the processes that lead to outcomes, emphasizing transparency, consistency, and impartiality in decision-making. It is important because it fosters public trust in institutions, promotes compliance with laws and regulations, and enhances perceptions of legitimacy. When individuals believe that processes are fair, they are more likely to accept outcomes, even if they are unfavorable, leading to greater social cohesion and cooperation. Ultimately, procedural justice contributes to a more equitable and just society.

C program to find greatest of three numbers?

# include<stdio.h>

main()

{

int a,b,c;

print f("enter the values of a,b,c");

scan f("%d%d%d",&a,&b,&c);

if((a>b)&&(a>c))

print f("Greatest value is a =%d",a);

else if((b>a)&&(b>c))

print f("Greatest value is b=%d",b);

else

print f("Greatest value is c=%d",c);

}

Why linear search is called sequential search?

A linear search is called a sequential search because a sequential search takes linear time and therefore has a worst-case time-complexity of O(n) for a data sequence of n elements. Although there are more efficient search algorithms than linear search, not all data containers are ideally suited to them. For example, although a binary search can be performed in quadratic time (O(log n)) when the data container is in sorted order, we can only achieve maximum efficiency when the data container also supports constant-time random-access. Arrays and vectors do support constant-time random-access, but if the container is not sorted then we must resort to the less-efficient linear search. Linked lists do not support constant-time random-access thus a linear search would be more efficient even if the list were in sorted order.

How do you make an a with a squiggly line over it?

Hold the Alt key down and type 0227.

or

Hold the Ctrl key down and type ~, which may require shift and a key next to the return key (depends on keyboard setup), and then type a.
