Answer:

Answer:

"a[0]=a[0]+10;", is the correct answer for the above question.

Explanation:

  • An array is defined as a user-defined data type used to store multiple variables of the same type in a continuous passion in a memory.
  • To declare an array a user needs to define the size and it referred many variables by one name but the index of that variable is different,
  • The array takes an index from 0 to (size-1). It means that the first index of the array is 0. So if the name of that array is A then the first variable name is A[0].
  • The above-question says that there is an array of name 'a' then its first variable name is a[0] then we can add 10 to its like "a[0]=a[0]+10". Here '=' is an assignment operator and '+' is an addition operator.

What does “default” refer to? the ability to be used as, or directly converted to, cash. the failure to pay back a loan. the amount of money borrowed. the price paid for the use of borrowed money.

Answers

The answer is "the failure to pay back a loan".

In computer systems, we have a different meaning to the word default. It is referred to the setting or option in a computer upon opening a program or application. But according to the dictionary, default refers to the failure to make a payment such as a loan.

Reversing the elements of an array involves swapping the corresponding elements of the array: the first with the last, the second with the next to the last, and so on, all the way to the middle of the array. Given an array a and two other int variables, k and temp, write a loop that reverses the elements of the array. Do not use any other variables besides a, k, and temp.

Answers

Answer:

// Assume that all variables a, n, temp have been declared.

 // Where a is the array, n is the array length, temp is a temporary

 // storage location.

 // Cycle through the array a.

 // By the time the loop gets halfway,

 // The array would have been reversed.

 // The loop needs not get to the end of the array.

 // Hence, the loop ends halfway into the array i.e n/2.

 for (int k = 0; k < n / 2; k++) {

   

  // Swap first and last, second and next-to-the-last and so on

  temp = a[k];

  a[k] = a[n - k - 1];

  a[n - k - 1] = temp;

 }

A pincode consists of N integers between 1 and 9. In a valid pincode, no integer is allowed to repeat consecutively. Ex: The sequence 1, 2,1, 3 is valid because even though 1 occurs twice, it is not consecutive. However, the sequence 1, 2, 2, 1 is invalid because 2 occurs twice, consecutively. Utilize a for loop and branch statements to write a function called pinCodeCheck to detect and eliminate all the consecutive repetitions in the row array pinCode. The function outputs should be two row arrays. The row array repPos contains the positions pinCode where the consecutive repeats occurs, and the row array pinCodeFix is a valid pincode with all the consecutive repeats removed in pinCode. Hint: The empty array operator [] is will be helpful to use.
