andreyandreev [35.5K]

Answer:

Follows are the modified code to this question:

#include <stdio.h>//defining a herader file

int main(void) //defining a main method

{

  int arrowBaseHeight = 0,arrowBaseWidth = 0,arrowHeadWidth = 0 ;//defining integer variable

  int i, j; //defining integer variable

  printf("Enter arrow base height:");//print message  

  scanf("%d", &arrowBaseHeight);//input value in arrowBaseHeight variable

  printf("Enter arrow base width:");//print message

  scanf("%d", &arrowBaseWidth);//input value  in arrowBaseWidth variable

  while (arrowHeadWidth <= arrowBaseWidth)//defining while loop to check arrowHeadWidth less then equal to arrowBaseWidth  

  {

      printf("Enter arrow head width:");//print message

      scanf("%d", &arrowHeadWidth);//input value in arrowHeadWidth variable

      printf("\n");//use for line spacing

  }

  // defining for loop for print vertical line of asterisk

  for (i = 0; i < arrowBaseHeight; i++)//defining for loop for print row  

  {

      for (j = 0; j < arrowBaseWidth; j++) //defining for loop for print column

      {

          printf("*");//print asterisk value

      }

      printf("\n");//use for line spacing

  }

//defining for loop for print reverse triangle

  for (i = arrowHeadWidth; i > 0; i--) //defining loop for input length  

  {

      for (j = i; j > 0; j--) //defining loop for triangle  

      {

          printf("*"); //print asterisk value

      }

      printf("\n");//use for line spacing

  }

  return 0;

}

Output:

please find attach file.

Explanation:

In the code, inside the method five integer variable "arrowBaseHeight, arrowBaseWidth, arrowHeadWidth, i, and j" is defined, in which the first three variables are used for input value from the user end, and "i and j" are used in the loop.

In the next step while loop is used for input the value, but in this code, mainly two for loop is used which can be defined as follows:

  • In the first loop, it is used the "arrowBaseHeight and arrowBaseWidth" variable to print the vertical line of the asterisk.
  • In the second loop, it uses the "arrowHeadWidth" variable to print the reverse triangle.

Lossless and lossy are the two (2) universally known categories of compression algorithms. Compare the two (2) categories of alg
Romashka-Z-Leto [24]

Answer:

The lossy compression method is also known as irreversible compression and is beneficial if the quality of the data is not your priority. It slightly degrades the quality of the file or data but is convenient when one wants to send or store the data. This type of data compression is used for organic data like audio signals and images. The algorithm use in Lossy compression include: Transform coding, DCT, DWT, fractal compression, RSSMS.

The Lossless compression method is also known as reversible compression and is capable of reconstituting the original form of the data. The quality of the data is not compromised. This technique allows a file to restore its original form. Lossless compression can be applied to any file format can improve the performance of the compression ratio. The algorithm use in Lossless compression include: RLW, LZW, Arithmetic encoding, Huffman encoding, Shannon Fano coding.

Advantage of Lossy compression: Lossy compression can achieve a high level of data compression when compared to lossless compression.

Advantage of Lossless compression: Lossless compression doesn’t degrade the quality of data during compression

Disadvantage of Lossy compression: Lossy compression degrades the quality of the data during compression

Disadvantage of Lossless compression: Lossless compression has less data holding capacity when compared to lossy method

Example of type of data for Lossless compression: Text

Example of type of data for Lossy compression: Audio
