Thread: scanf with switch statement, weird behavior

Below is the code that I'm having trouble with:

Code:

while(TRUE){
        
        printf("Type in one of options below:\n1. Create File in root\n2. Navigate to Directory\n3. Quit\n");
        printf(">>");
        scanf("%d", &option);
        fflush(stdin);
        switch(option){
            case 1: 
                    createFile(disk,0);
                    break; 
            case 2: 
                    navDir(disk, 0);
                    break; 
            case 3: 
                    writeStructs(disk);
                    exit(1);
                    break;
            
            default: break;
            
        }
    }

On the first run everything works, but after one of the functions returns back to a switch statement scanf doesn't wait for input and I get the output as below:

Code:

Type in one of options below:
1. Create File in root
2. Navigate to Directory
3. Quit
>>1
Enter file name and extension (file.doc): test.doc
Enter Content terminated by %>>this is a test%
Type in one of options below:
1. Create File in root
2. Navigate to Directory
3. Quit
>>Enter file name and extension (file.doc): Enter Content terminated by %>>

I tried flushing the buffer and using if statements instead of switch, but nothing seems to help. Any idea why this is happening?
