"int main()
char str1[5]="vector", str2[5]="vectoa";
int i;
printf("i = %d",i);
return 0;

Output: i = 118.
How the i value is getting 118?"

1. strings are 6 character long but initialized to 5. Correct initialization would be str1[] = "vector", str2[]="vectoa";

2. Expected behaviour of strcmp. strcmp returns the distance between first difference between two strings.

strcmp(str1, str2) for strings defined as in #1 would be 17 (ascii (r) - ascii(a)).

for str1[] = "vector", str2[] = "vectop", strcmp(str1, str2) will return 2 (ascii (r) - ascii(p))

As for i = 118, because of comparing unintended values (could be ascii(v) - ascii(NULL) ??)

internally working code is the answer
