How to compare to strings in embedded C ?

[Sunil Hiremath]

Hi friends,

I want to compare the two strings in embedded C. I'm using two character arrays to store string.
In one array I'm saving string received by UART and in another array I'm saving user defined string. So I want to compare both the strings for my further process.

Any help will be thankful.

many embedded C compilers implement the string compare functions in string.h
https://www.cplusplus.com/reference/cstring/

otherwise you can compare the arrays element by element as with any other type of array

Hi horace1,

Thank you for your help. I will check the Functions in compiler. and for comparing array elements I have two different size arrays.

if you require to compare other types of array you can use memcmp() where you specify the number of bytes to compare
