Tips To Improve System Speed

*)  Let your PC boot up completely before opening any applications.

*) Refresh the desktop after closing any application. This will remove any unused files from the RAM. 


*) Do not set very large file size images as your wallpaper. Do not keep a wallpaper at all if your PC is low on RAM (less than 64 MB).

*) Do not clutter your Desktop with a lot of shortcuts. Each shortcut on the desktop uses up to 500 bytes of RAM

*) Empty the recycle bin regularly. The files are not really deleted from your hard drive until you empty the recycle bin.

*) Delete the temporary internet files regularly.

*) Defragment your hard drive once every two months. This will free up a lot of space on your hard drive and rearrange the files so that your applications run faster.

*) Always make two partitions in your hard drive. Install all large Softwares (like PSP, Photoshop, 3DS Max etc) in the second partition. Windows uses all the available empty space in C drive as virtual memory when your Computer RAM is full. Keep the C Drive as empty as possible.

*) When installing new Softwares disable the option of having a tray icon. The tray icons use up available RAM, and also slow down the booting of your PC. Also disable the option of starting the application automatically when the PC boots. You can disable these options later on also from the Tools or preferences menu in your application.

*) Protect your PC from dust. Dust causes the CPU cooling fan to jam and slow down thereby gradually heating your CPU and affecting the processing speed. Use compressed air to blow out any dust from the CPU. Never use vacuum.

     

Program to find whether a string is palindrome or not.

#include
#include

void main()
{
char s1[20],s2[20];
clrscr();
printf("enter a string: ");
scanf("%s",s1);
strcpy(s2,s1);
strrev(s2);
if(strcmp(s1,s2)==0)
printf("string is a palindrome");
else
printf("not a palindrome string");
getch();
}


Output:
enter a string: abc
not a palindrome string

Program to find factorial of a number using recursion.

#include
#include

void main()
{
int n;
clrscr();
printf("enter number: ");
scanf("%d",&n);
if(n<0)
printf("invalid number");
else
printf("%d!=%d",n,fact(n));
getch();

}
int fact(int x)
{
if(x==0)
return 1;
else
return(x*fact(x-1));
}

Output:
enter number: 5
5!=120
 

Program to find largest of two numbers using functions.

#include
#include

void main()
{
void max();
clrscr();
max();
getch();
}
void max()
{
int a[5],max,n,i;
printf("How many no's you want to enter: ");
scanf("%d",&n);
printf("Enter element for the array: ");
for(i=0;i
scanf("%d",&a[i]);
max=a[0];
for(i=1;i<5;i++)
{
if(max
max=a[i];
}
printf("maximum no= %d",max);
}


Output:
How many no’s you want to enter: 4
Enter element for array: 4
5
6
1
maximum no: 6

Program to show call by reference.

#include
#include
void main()
{
int a,b,*aa,*bb,swap();
clrscr();
a=5;
b=10;
aa=&a;
bb=&b;
printf("value of a= %d & value of b=%d before swap",a,b);
swap(aa,bb);
printf("\nvalue of a=%d & b=%d after swap",a,b);
getch();
}
int swap(int *x,int *y)
{
int temp;
temp=*x;
*x=*y;
*y=temp;
}

 

Output:
value of a= 5 & value of b=10 before swap
value of a=10 & b=5 after swap

Program to show call by value..

#include
#include

void main()
{
int a,b,swap();
clrscr();
a=5;
b=10;
printf("value of a=%d & value of b=%d before swap ",a,b);
swap(a,b);
printf("\nvalue of a =%d & b=%d after swap",a,b);
getch();
}
int swap(int x,int y)
{
int temp;
temp=x;
x=y;
y=temp;
}
 

Output:
value of a=5 & value of b=10 before swap
value of a=5 & b=10 after swap
