String Functions-strcat Consider the following code: char string1[25] -\"Total Eclipse \"; char string2[11] = \"of the Sun\"; cout

Solution

Code:

#include <iostream>
#include <cstring>
using namespace std;

void strcat( char* string1, char* string2 ){
   int l1 = strlen(string1);
   int l2 = strlen(string2);
   for(int i = 0; i < l2; i++){
       string1[l1+i] = string2[i];
   }
   string1[l1+l2] = \'\\0\';
}

int main(){
   char string1[20] = \"Total Eclipse \";
   char string2[11] = \"of the Sun\";
   cout << string1 << endl;
   cout << string2 << endl;
   strcat( string1, string2 );
   cout << string1 << endl;
}

1. Strings are concatenated

2. Seems to be running same. Note that, string1 has only 20 characters, concatenation results in size 20, still prints fine
