I am a newbie in C. I am using FIFO to receive the data from users and send the data to Server. In my code, the value of burst that cannot send to the server, even though the others worked well. I do know why it happened because I have followed the instruction carefully. This is my code. client-side:

#include  #include  #include  #include  #include  #include  #include  #include  struct values{ char privateFIFO[14]; int memRequest; int page; int burst; float throughput; float aveTurnaround; float aveWaiting; }PCB; int main () { int fda;// write to server int fdb; // read to server char temp[14]; int clientId; clientId = getpid(); strcpy(PCB.privateFIFO, "FIFO_"); //get name of private FIFO sprintf(temp, "%d", clientId); strcat(PCB.privateFIFO, temp); printf(" FIFO name is: %s",PCB.privateFIFO); printf(" Enter the amount of memory memory request: "); printf("The amount MUST NOT be greater than 4096 or less than 0: "); scanf("%d", &PCB.memRequest); while(PCB.memRequest  4096) //Send an Error message if the request is invalid { printf(" INVALID REQUEST!!!. "); printf("The amount of request MUST NOT be greater than 4096 or less than 0: "); scanf("%d", &PCB.memRequest); } printf(" Enter the amount of CPU Burst: "); scanf("%d", &PCB.burst); if ((mkfifo(PCB.privateFIFO,0666) 
The server-side:
 
#include  #include  #include  #include  #include  #include  #include  #include  struct values{ char privateFIFO[14]; int memRequest; int page; int burst; float throughput; float aveTurnaround; float aveWaiting; }; int main(){ int fda; // read from client int fdb; // write to client char temp[14]; // buffer hold a character int clientNum; // number of clients int i,j; // loop counter int burst[16]; int frame[16]; int frameSize[16]; int wt[16],tat[16]; int holder = 0; int counter = 0; int page = 0; int request; int choice; float throughput=0.0; float avwt=0.0; float avtat=0.0; printf(" Assume that in the main memory contain 16 frame Size "); printf("Each frame has 256 bits "); printf("How many clients: "); scanf("%d", &clientNum); struct values PCB[clientNum]; for (i = 0; i  
The screenshot:
 
 
As you can see, the client accepts all values from user. But only the values of PCB.memRequest and FIFO sent to server successfully, the value of PCB.burst cannot send. Please Help me to solve this error :(
