C sizeof char array

Hello i'm beginner in C programming. I'm making program that should crawls though elements of a string, the string is input from the user. The problem is that I need the size of the characters in the string I have try a lot of thing none of them worked. 

    for(int i = 0; i <= cUserInput; i++){
        if(&cUserInput[i] == cFirstLineR[i]){
        printf("Check///Failed\n");
    }

cUserInput is the user input. I need its size.

cFirstLineR is an array of characters to camper with.

Use the function strlen(const char* str) to get a strings' size. It will count the characters until the NUL terminator. See reference here:http://www.cplusplus.com/reference/cstring/strlen/

NOTE: to use it you have to include the header "string.h"
