character arrays behaving erratic

Using Arduino Programming Questions
#1

Hi all

I am at a complete loss. I have pasted the code in below but cannot figure out why the character arrays are not storing values.

char cAT1[6];
char cAT2[6];
while ((strcmp(cAT1,“AT+CCL”) != 0) || (strcmp(cAT2,“CCLK:”) != 0)){
sBuffer = time_request();
Serial.println(sBuffer);

for (int i = 0; i <= 6; i++){
cAT1 = sBuffer*; // there is a website bug here, this line should have a i between brackets after sBuffer*
* if (i == 6) cAT1[6] = ‘\0’;*
* }*

* Serial.print("AT1 = ");*
* Serial.println(cAT1);*
* Serial.print("AT2 = ");*
* Serial.println(cAT2);*

* for (int i = 0; i <= 6; i++){*
_ cAT2 = sBuffer[i+11];
* if (i == 6) cAT2[6] = ‘\0’;
 }*_

* Serial.print("AT1 = ");*
* Serial.println(cAT1);*
* Serial.print("AT2 = ");*
* Serial.println(cAT2);*
* Serial.println(“End--------------------”);*
* }*
Now the response that I get is the following:
AT+CCLK?
+CCLK: “04/01/01,00:17:25+08”
OK
AT1 = AT+CCL
AT2 =
AT1 =
AT2 = +CCLK:
End--------------------
As you can see, for some unknown reason, AT1 is rewritten after i run the second for loop.
Any help would be massively appreciated.

Posting complete code that actually compiles and doing so using CODE TAGS would be massively appreciated.

See Item #6 here: Read this before posting a programming question .... The title says it all.

#3 
char cAT1[6];
char cAT2[6];
while ((strcmp(cAT1,"AT+CCL") != 0) || (strcmp(cAT2,"CCLK:") != 0))

A 6 element array can NOT hold AT+CCL and a terminating NULL.

   for (int i = 0; i <= 6; i++){
        cAT2[i] = sBuffer[i+11];
        if (i == 6) cAT2[6] = '\0';
    }

A 6 element array does NOT have a position 6.

When you sh*t on memory you don’t own, you can NOT expect rational behavior from a program.

On the other hand, the problem was quite obvious from the code that was (poorly) posted.
