Write a program to store elements in m x n 2D array (Matrix)

m(row) and n(coloumns) are taken from user.. Elements are taken from user.. matrix is displayed in tabular form..

This should be your first program for Matrix.

Select To use this code as it is.. select and copy paste this code into code.cpp file :)

1. #include<iostream.h>
2. #include<conio.h>
3. void main()
4. {
5. clrscr();
6. int a[10][10],m,n,i,j;
7. cout<<"Enter number of rows: ";
8. cin>>m;
9. cout<<"Enter number of coloumns: ";
10. cin>>n;
11. cout<<endl<<"Enter elements of matrix: "<<endl;

14. for(i=0;i<m;i++)
15. {
16. for(j=0;j<n;j++)
17. {
18. cout<<"Enter element a"<<i+1<<j+1<<": ";
19. cin>>a[i][j];
20. }
21. }
22. cout<<endl<<"Displaying Matrix: "<<endl<<endl;
23. for(i=0;i<m;i++)
24. {
25. for(j=0;j<n;j++)
26. {
27. cout<<a[i][j]<<" ";
28. }
29. cout<<endl<<endl;
30. }
31. getch();
32. }

write a program to store and display 10 numbers in an array

10 numbers are first stored in array and then the array is displayed.

This should be your first array program.

Select To use this code as it is.. select and copy paste this code into code.cpp file :)

1. #include<iostream.h>
2. #include<conio.h>
3. void main()
4. {
5. clrscr();
6. int ar[10];
7. cout<<"Enter array element: "<<endl;
8. for(int i=0;i<10;i++)
9. //Coding by: Snehil Khanor
10. //http://WapCPP.blogspot.com
11. {
12. cout<<"Enter element "<<i<<": ";
13. cin>>ar[i];
14. }
15. cout<<"Elements of array: "<<endl;
16. for(i=0;i<10;i++)
17. cout<<"Element at index number "<<i<<" is: "<<ar[i]<<endl;
18. getch();
19. }

Write a program to display the input

This is an ideal first program for learning "cin"

Two numbers are taken from the user and then displayed as output.

Select To use this code as it is.. select and copy paste this code into code.cpp file :)

1. #include <iostream.h>
2. #include <conio.h>
3. void main()
4. {
5. clrscr();
6. int a,b;
7. cout<<"enter first no. ";
8. cin>>a;
9. //Coding by: Snehil Khanor
10. //http://WapCPP.blogspot.com
11. cout<<"enter second no. ";
12. cin>>b;
13. cout<<"First no. is "<<a;
14. cout<<"\nSecond no.is "<<b;
15. getch();
16. }

Write a program to output a messege

This is an ideal First C++ (CPP) program.

All necessary things are described with in the program in comments.

Select To use this code as it is.. select and copy paste this code into code.cpp file :)

1. #include <iostream.h> //These are the Header files and are essential..
2. #include <conio.h> // They varies program to program.
3. void main() //This is a special type of function.Program starts and ends in MAIN.
4. {
5. //Coding by: Snehil Khanor
6. //http://WapCPP.blogspot.com
7. clrscr(); //This clears previous outputs from the output screen
8. cout<<"Hello India"; //This is responsible for diplaying a messege
9. cout<<"\nThis is my first C++ programme";
10. getch(); //This helps to sustain the output on Screen.
11. }
