strcat(): Concatenation of strings in C

We can use string function strcat() to concatenate strings.
The second string is added at the end of the first string.
strcat(destination_string, source_string);
We will use this and here is one example.
#include <stdio.h>
#include <string.h>
int main(void){
char var1[20]="plus2net";
char var2[]="welcome to ";
strcat(var2,var1);
printf(var2);
return 0;
}
The output of above code is here
welcome to plus2net
  • Source string is not affected
  • Source string is added at the end of the destination string.
