if statements did not work correctly in C
-3
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 frameSizen");
printf("Each frame has 256 bitsn");
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?
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

while ((choice !=1) && (choice !=2))
{
code.....
}
after the loop you will end up with 2 choices either 1 or 2 so :
if (choice == 1)
{
printf("FCFS");
}
else
{
printf("Round Robind");
