Program Plan Intro

Given C Code:

void* basic_memset(void *s, int c, size_t n)

{

size_t cnt = 0;

unsigned char *schar = s;

while (cnt < n)

{

*schar++ = (unsigned char) c;

cnt++;

}

return s;

}

Cycles per element (CPE):

  • The CPE denotes performance of program that helps in improving code.
  • It helps to understand detailed level loop performance for an iterative program.
  • It is appropriate for programs that use a repetitive computation.
  • The processor’s activity sequencing is controlled by a clock that provides regular signal of some frequency.

Loop unrolling:

  • It denotes a program transformation that would reduce count of iterations for a loop.
  • It increases count of elements computed in each iteration.
  • It reduces number of operations that is not dependent to program directly.
  • It reduces count of operations in critical paths of overall computations.

IN C++ You have given an array aa of length n and an integer x to a brand new robot. What the robot does is the following: it iterates over the elements of the array, let the current element be q. If q is divisible by x, the robot adds x copies of the integer q/x to the end of the array, and moves on to the next element. Note that the newly added elements could be processed by the robot later. Otherwise, if q is not divisible by x, the robot shuts down. Please determine the sum of all values of the array at the end of the process. Input The first input line contains a single integer tt (lâ%oatâ%o¤100) â€" the number of test cases. The first line of each test case contains two integers n and x (1â%o¤nâ%o010^5, 2â%oaxâ%o ¤10^9) â€" the length of the array and the value which is used by the robot. The next line contains integers al, a2, .., an (lâ%o¤aiâ%o¤1O^9) â€" the initial values in the array. It is guaranteed that the sum of valuesn over all test cases does not exceed 10^5 Output For…
Write only the function definition: Implement the following function definition: int CrazyWord(char word [ ]); //input: a character array with a null character (string) //sets all of the characters in the word to lowercase letters //changes any lowercase ‘o’ letters to hashtags ‘#’ //returns the number of hashtags that are now in the word
Write a function in C language that will take a 2D Array of size 3x3 from the user. Your Program should: 1. Prompt the user to enter 2D array of size 3x3. 2. Calculate the sum of all rows. 3. Calculate the sum of all columns 4. Return 1 if the sum of all rows is greater than sum of all columns, 0 otherwise.   Your main program should print the result based on the returned values.
