Is this C programming for Arduino? I have this in my Bluetooth module code in Arduino but don't know what the purpose of it and what it means.

int i=0;

int m=0; delay(500);

if (Serial1.available() > 0) {

while (Serial1.available() > 0) {

inSerial[i]=Serial1.read();

i++; }

inSerial[i]='\0';

Check_Protocol(inSerial); }}

if(!strcmp(inStr,"read")){

(Here I have my Serial1.println lines)

for(m=0;m<11;m++){

inStr[m]=0;}

i=0;}

else{

for(m=0;m<11;m++){

inStr[m]=0; } i=0;
