ISC Computer Science Practicals: Solved

Write a program to declare a matrix A [][] of order (MXN)

where 'M' is the number of rows and 'N' is the number of

columns such that both M and N must be greater than 2 and

less than 20. Allow the user to input integers into this matrix.

Perform the following tasks on the matrix:

1. Display the input matrix

2. Find the maximum and minimum value in the matrix and display

them along with their position.

3. Sort the elements of the matrix in ascending order using any

standard sorting technique and rearrange them in the matrix.

Output the rearranged matrix.

Sample input Output

INPUT:

M=3

N=4

Entered values: 8,7,9,3,-2,0,4,5,1,3,6,-4

Original matrix:

8 7 9 3

-2 0 4 5

1 3 6 -4

Largest Number: 9

Row: 0

Column: 2

Smallest Number: -4

Row=2

Column=3

Rearranged matrix:

-4 -2 0 1

3 3 4 5

6 7 8 9

open GL Programming in LINUX

To compile a program (using open GL graphics library) in Linux, go to the current directory where the program is residing say test.c. type the following command gcc -o xyz test.c -lglut -lGLU -lGL -lGLU make sure you have the open GL library installed! After the execution of the command a output file with name xyz will be created in the current directory. To run the output file type in the following command ./xyz

To sum up consider a program vinod.c in the folder Graphics, to execute it perform the following steps.

administrator@ubuntu:~/Graphics$ gcc -o vin vinod.c -lglut -lGLU -lGL -lGLU

administrator@ubuntu:~/Graphics$ ./vin

Here is an example of a simple program which will just create a window with a text

#include <GL/glut.h>

void

display(void) {

glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

glutSwapBuffers();

}

int main(int argc, char **argv) {

glutInit(&argc, argv);

glutInitDisplayMode(GLUT_DOUBLE | GLUT_RGB | GLUT_DEPTH);

glutCreateWindow("MY FIRST GRAPHICS PROGRAM");

glutDisplayFunc(display);

glutMainLoop();

return 0;

}
