Question

3. Copy a Picture in JPG format from the internet, divide it into 6 sub-sections and change the location as shown below to create a new Picture and write the program that gives the original Picture and the changed Picture (add pictures to the assignment with the program) 2 + 6 4. write the program of the given pseudocode and run it on an example. function LG (x, y, 7, new_x) : 0 sum dofor i = 0, f = y, dofor j = 0,n if it then f=f*(new_x - x)/(x,- x) endif enddo sum = sum + 1 enddo LG = sum

Answer 1

ANS. 3. The image pixel is changed using C++ language. The program is as follows:

#include <iostream>

using namespace std;

int main()
{
int i, j;
int width = 4, height = 4;
  
int img[3][2] = {
{1, 2},
{3, 4},
{5, 6},
};
  
cout << "Image: \n";
for(i=0; i<3; i++)
{
for(j=0; j<2; j++)
{
cout << img[i][j];
cout << "\t";
}
cout << "\n";
}
  
cout<< "Reversed Image: \n";
  
int imgREV[3][2];
  
cout << "Image: \n";
for(i=0; i<3; i++)
{
for(j=0; j<2; j++)
{
imgREV[2-i][1-j] = img[i][j];
}
}
  
int temp = 0;
temp = imgREV[0][1];
imgREV[0][1] = imgREV[1][1];
imgREV[1][1] = temp;
  
for(int m=0; m<3; m++)
{
for(int n=0; n<2; n++)
{
cout << imgREV[m][n];
cout << "\t";
}
cout << "\n";
}

return 0;
}

OUTPUT:

Image: 2 3 4 5 6 Reversed Image: Image: 6 3 4 5 2 1 ... Program finished with exit code 0 Press ENTER to exit console.

ANS. 4. The pseudocode is programmed using C++ language. The program is as follows:

void LG(int x, int y, int n, int new_x)
{   
int sum = 0;
int i = 0;
int f;
  
do{
f = y;
do{
if(i!=j)
{
f = f * (new_x - x)/(xi - xj);
}
j += 1;
}while(j<n)
sum += f;
i += 1;
}while(i<n)
  
}
