C Program to Concat Two Strings with using Library Function

Concat Two Strings Using Library Function

#include<stdio.h>
#include<string.h>

int main() {
   char str1[100];
   char str2[100];
   char str3[100];
   int len;

   printf("\nEnter the String 1 : ");
   gets(str1);

   printf("\nEnter the String 2 : ");
   gets(str2);

   strcpy(str3, str1);
   strcat(str3, str2);

   printf("\nConcated String : %s", str3);

   return (0);
}

#include<stdio.h>

#include<string.h>

int main() {

char str1[100];

char str2[100];

char str3[100];

int len;

printf("\nEnter the String 1 : ");

gets(str1);

printf("\nEnter the String 2 : ");

gets(str2);

strcpy(str3, str1);

strcat(str3, str2);

printf("\nConcated String : %s", str3);

return (0);

}

Explain me ?

Copy “str1” into “str3”.
Then Concat “str2” to “str3” , after concating result will be stored in “str3”
strcat,strcpy functions are included in Header File : string.h

Functions Required :

gets : For Accepting String
strcpy : String Function for Copy one string into other
strcat : String Function for Concating two Strings
