C Program to Simulate Priority Scheduling CPU scheduling Algorithm

The following C program implements Simulation of  priority scheduling (CPU Scheduling algorithm). Each process or job is given a priority. The priority is represented using a positive integer. The priority increases as the value of the integer decreases.

Program:

#include<stdio.h>
struct process{

2 Different C and C++ Programs to Check Whether a Given String is Palindrome or Not

Here i am writing two different programs to check whether a given string (text) us palindrome or not. There are C and C++ programs for this.

C Programs:

(i) Using string functions:

#include<stdio.h>
#include<string.h>
#include<conio.h>
void main()
{
char a[100],b[100];
printf("Enter the string to check if palindrome or not\n");
gets(a);
strcpy(b,a);
strrev(b);
if(strcmp(a,b)==0)
printf("\nEntered string is palindrome");
else
printf("\nEntered string is not palindrome");
getch();
} 

(ii) Comparing Character by Character

#include<string.h>
#include<stdio.h>
#include<conio.h>
void main()
{
int len,i;
char a[100];
printf("Enter the string to check whether it is palindrome or not\n");
gets(a);
len=strlen(a);
for(i=0;i<len/2;i++)
{
if(a[i]!=a[len-i-1])
break;
}

if(i==len/2)
printf("\nEntered string is palindrome");
else
printf("\nEntered string is not palindrome");
getch();
}

C++ Programs:

(i) Using String functions:

Program to Understand Bitwise Operators

This program is to understand working of bitwise operators

#include<stdio.h>

main ()

{

unsigned int a = 60; /* 60 = 0011 1100*/

unsigned int b = 13; /* 13 = 0000 1101 */

printf ("a=60 ( 0011 1100)\nb=13 ( 0000 1101)\n"); 

int c = 0;

c = a&b ; /* 12 = 0000 1100 */

printf ("a&b=%d\n",c );

c = a | b ; /* 61 = 0011 1101 */

printf ("a|b=%d\n",c );

c = a ^ b ; /* 49 = 0011 0001 */

printf ("a^b=%d\n", c );

c = ~ a; /*-61 = 1100 0011 */

printf ("~a=%d\n" , c );

c = a << 2 ; /* 240 = 1111 0000 */

printf ("a<<2=%d\n" , c );

c = a >> 2 ; /*15 = 0000 1111*/

printf ("a>>2=%d\n" , c );

}
