// Program to Concatenate Two Strings using strcat()

#include <stdio.h>
#include <string.h>
main()
{
char s1[20], s2[20];
printf("\nEnter first string: ");
gets(s1);
printf("\nEnter second string: ");
gets(s2);
strcat(s1, s2);
printf("\nThe concatenated string is: %s", s1);
getch();
}

Concatenation of strings means taking two strings and joining them sequentially into one. For example, you can use the + operator to concatenate two strings:

var str1:String = "green";
var str2:String = "ish";
var str3:String = str1 + str2; // str3 == "greenish"
