You all please run this code. It will give some negative result cause static char str3[] = "Daffo";memory is fixed. So this concatination is not possible. Target string should have enough memory.

static is used just to confuse the students, it dosen't make any difference. static is a type of storage classs.

All strings declare in static it cannot modifie. So zero is answer.

Will str3 array can store dills also?? I think not as its size is just 6 byte.
So I dont agree with answer...!!!

step 1: strcpy(str2,str1) cpoy the str1="dills" into str2.

step 2: strcat(str3,str2) append the dills at the end of Daffo.

step 3: strcmp(str3,"Daffodils") returns the no. of charecters of str3 which are not find in Daffodills.

step 4: since both strings are same so results will be 0(zero)
