Thread: strcat makes program crash

//RANDOM SENTENCE GENERATOR USING STRCAT

//I added the strcat command the program crashes..
//This program is suppossed to genterate random sentences..
//My teacher says that we HAVE TO USE STRCAT to catonate the sentences..
//IN CLASS MY PROFESSOR COULDNT GET THE PROGRAM TO RUN EITHER



#include<iostream>
#include<ctime>
#include<cstdlib>
#include<string.h>// I also tried <cstring>
