C Program to Concat Two Strings with using Library Function

#include
#include
#include
void 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);
getch();
}

---

Explain me ?

1. Copy “str1″ into “str3″.
2. Then Concat “str2″ to “str3″ , after concating result will be stored in “str3″
3. 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
