String functions programs

       Program for comparison between two strings :-

       #include<stdio.h>
       #include<string.h>
       main()
       {    
               char a[100], b[100];   
               printf("Enter the first string\n");   
               gets(a);   
               printf("Enter the second string\n");   
               gets(b);   
               if( strcmp(a,b) == 0 )      
               printf("Entered strings are equal.\n");   
               else      
               printf("Entered strings are not equal.\n");   
               return 0;
         }

       Program for copy of two strings :-

       #include<stdio.h>
       #include<string.h>
       main()
       {
               char source[] = "C program";   
               char destination[50];   
               strcpy(destination, source);   
               printf("Source string: %s\n", source);   
               printf("Destination string: %s\n", destination);   
               return 0;
        }

       Program for String Reverse :-
       
       #include<stdio.h>
       #include<string.h>
       main()
       {   
               char arr[100];   
               printf("Enter a string to reverse\n");   
               gets(arr);   
               strrev(arr);   
               printf("Reverse of entered string is \n%s\n",arr);   
               return 0;
        }


        Program for Append the two Strings :-

        #include<stdio.h>
        #include<conio.h>
        #include<string.h>
        main()
        {   
               char a[100], b[100];   
               printf("Enter the first string\n");   
               gets(a);   
               printf("Enter the second string\n");   
               gets(b);   
               strcat(a,b);
               printf("String obtained on concatenation is %s\n",a);   
               getch();   
               return 0;
         }
