Comparing two strings in C? [duplicate]

Answer 1

You try and compare pointers here, not the contents of what is pointed to (ie, your characters).

You must use either memcmp or str{,n}cmp to compare the contents.

Answer 2

To compare two C strings (char *), use strcmp(). The function returns 0 when the strings are equal, so you would need to use this in your code:

if (strcmp(namet2, nameIt2) != 0)

If you (wrongly) use

if (namet2 != nameIt2)

you are comparing the pointers (addresses) of both strings, which are unequal when you have two different pointers (which is always the case in your situation).

Answer 3

You need to use strcmp:

strcmp(namet2, nameIt2)

Answer 4

To answer the WHY in your question:

Because the equality operator can only be applied to simple variable types, such as floats, ints, or chars, and not to more sophisticated types, such as structures or arrays. To determine if two strings are equal, you must explicitly compare the two character strings character by character.

Answer 5

You are currently comparing the addresses of the two strings.

Use strcmp to compare the values of two char arrays

 if (strcmp(namet2, nameIt2) != 0)

Answer 6

The name of the array indicates the starting address. Starting address of both namet2 and nameIt2 are different. So the equal to (==) operator checks whether the addresses are the same or not. For comparing two strings, a better way is to use strcmp(), or we can compare character by character using a loop.
