String

1.  Write a program take an address form user and check it is Kathmandu or not in C language.
   
   #include<stdio.h>

   #include<string.h>

   int main()

   {

       char address[20];

       printf("Enter an address: ");

       scanf("%s", address);

       if(strcmp(address, "kathmandu") == 0)

       {

           printf("You have enter Kathmandu");

       }else{

           printf("You havenot enter Kathmandu");

       }

       return 0;

   }

   
   
   
   
   
   
2. Write a program, take 3 string data from user and find smallest in C language.
   
   
   #include<stdio.h>

   #include<string.h>

   int main()

   {

       char a [20], b[20], c[20];

       printf("Enter first string data: ");

       scanf("%s", a);

       printf("Enter second string data: ");

       scanf("%s", b);

       printf("Enter third string data: ");

       scanf("%s", c);

       if(strcmp(a,b) >= 0 && strcmp(c,b) >= 0)

       {

           printf("The smallest string is %s", b);

       }

       else if(strcmp(a,b) <= 0 && strcmp(a,c) <= 0)

       {

           printf("The smallest string is %s", a);

       } else

       {

           printf("The smallest string is %s", c);

       }

       return 0;

   
   
   
   
   
   
   
3. Enter Two Strings and use strcat
   #include <stdio.h>
   #include<string.h>
   int main(){
   char str1[10];
   char str2[10];
   printf("Enter Two strings:\n");
   gets(str1);
   gets(str2);
   printf("\nTwo string concantinated as %s",strcat(str1,str2));
   return 0;}
   
   
   
   
4. Enter Two Strings and use strlen
   #include <stdio.h>
   #include<string.h>
   int main(){
   
   
   char str1[10];
   char str2[10];
   
   
   printf("Enter Two strings:\n");
   gets(str1);
   gets(str2);
   
   
   printf("Length of Fist is %d \n",strlen(str1));
   printf("Length of 2nd is %d \n",strlen(str2));
   return 0;}
