I am trying to make a simple text based menu in C. I am using a infinite while loop and breaking when I get the character to exit the menu. However, after inputing a character that isn't the exit character, it loops through the menu twice before asking for another input. My code is as follows:
while(1){
printf("Please select an option: \na) Evaluate exponential function\nb) Evaluate sin function\nc) Exit\n");
scanf("%c",&ch);
if(ch == 'd')
{
break;
}
}
What could be causing this and how could I fix it? My best guess is that it is grabbing an extra character from the scanf and using that the next time it asks for input.
I appreciate any help with this. Thanks.
