Be careful about array size when u are using strcpThis tip submitted by Bhushan Verma on 2005-10-19 03:17:26. It has been viewed 49234 times.Rating of 5.4 with 258 votes Array/Buffer Overflow If we copy or insert data more into an array of limited size, it is referred as array overflow. Look at the following code: char var1[10]; char var2[7] = \"bhushan\"; /* '\0' is not added ,as size is given as 7*/ strcpy( var1, var2 ); Here, we can find that var2 (�bhushan�) is not terminated with a Null terminator (�\0�). So when we copy var2 to var1 using strcpy( ), the strcpy( ) routine will copy all the character to var2 until it finds �\0� in memory. So array overflow may result in memory overwrite!
