C++ programs examples

------------------------------------------------------------------------------------------------
click the unit you want to know/understand.
--------------------------------------------------------------------------------------

1) C++ basic programs:-

It contains basic fundamental of C++ programs. Like, inputs outputs,operators,strings etc.

2)C++ if..else programs:

It contains programs related to conditions and decisions. Like if program, if..else program,if..else if program,switch program ,break and continue program.

3. Loop related programs(loop , nested loop):-

It contains programs using while, or for or do..while loop. It is used to solve complex problem in very say way. We can use any loop to solve any program.

4. Array related programs:-

It contains program using one and multidimensional array. Array is used to use as pointer. It is helpful when we write a program for multiple data using same variable.

5.Array with string programs:

If we want to to write program for strings. then either we can use directly string or we can use array with string.It contains programs related to string processing (with/out library)

6.Function related programs:

We can understand what is function and how to use it. It is helpful to solve complex program in divide and conquer process.It contains programs using user defined function. Click the above link to know more.

7.struct,typedef and union related program :

This section contains programs using struct, union and typedef . We can be clear about what is struct,union and typedef through examples.

8 Pointer programs:

When we write program by using memory directly, then pointer is helpful. It also becomes faster. Here we can get programs related to pointer, array as pointer, pointer as an array, pointer in function, call by value and call by reference. We can also use pointer for strings.

9 Data file handling related program:

It contains programs using file handling functions etc. If we want our data permanent then we have no option than this.It makes our entered data permanent on hard disk.

------------------------------------------------------------------------------------------------------------------

Now we are gonna talk about object Oriented program in detail.

1. Object and class program

program to understand struct pointer using typedef

//understanding struct pointer with typedef
#include <stdio.h>
#include <stdlib.h>
typedef struct reco
{
int a;
float b;
char c;
char city[100];
}record;
int main()
{
typedef record *p;//pointer declaration of struct type record
p pointer;//pointer declartion
pointer=(p) malloc (sizeof(record));//memory allocation to variable pointer
pointer->a=10;//value assignment
pointer->b=3.14;//value assignment
pointer->c='a';//value assignment
strcpy(pointer->city,"Kathmandu");//value being copied
printf("i=%d \nf=%f\nc= %c\n",(*pointer).a,(*pointer).b,(*pointer).c);//value printing
printf("the city=%s\n",pointer->city);
free(pointer);
return 0;
}
