I am a new beginner in C This is my code:
#include <stdio.h>
int main(void) {
int choice;
int clientNum;
printf("\nAssume that in the main memory contain 16 frameSize\n");
printf("Each frame has 256 bits\n");
printf("How many clients: ");
scanf("%d", &clientNum);
printf("\nPlease choose the Scheduling Algorithm 1. FCFS 2.Round Robin: ");
scanf("%d", &choice);
while(choice !=1 || choice !=2){
printf("\nINVALID!!! The Server only has either FCFS or Round Robind Algorithm");
printf("\nPlease choose the Scheduling Algorithm again 1. FCFS 2.Round Robin: ");
scanf("%d", &choice);
}
if(choice==1){
printf("FCFS");
}
if(choice==2){
printf("Round Robind");
}
return 0;
}
I want to compare the value of choice with number 1 and 2. However, If statements did not work correctly. it did not compare choice with any value Is there any error in syntax or logic? Please help me!!! :(
The output:
gcc version 4.6.3
Assume that in the main memory contain 16 frameSize
Each frame has 256 bits
How many clients: 3
Please choose the Scheduling Algorithm 1. FCFS 2.Round Robin: 1
INVALID!!! The Server only has either FCFS or Round Robind Algorithm
Please choose the Scheduling Algorithm again 1. FCFS 2.Round Robin: 2
INVALID!!! The Server only has either FCFS or Round Robind Algorithm
Please choose the Scheduling Algorithm again 1. FCFS 2.Round Robin: 1
INVALID!!! The Server only has either FCFS or Round Robind Algorithm
Please choose the Scheduling Algorithm again 1. FCFS 2.Round Robin:
