You don't necessarily have to convert the input to a number, can't you read the input as a character and then in the switch statement use '1', '2', etcetera?Code:
// Main menu state-handler functionvoid mainMenu() { int choice; printf("\nEnter your choice: "); if (scanf("%d", &choice) == 1) { switch (choice) { case 1: currentState = doThings; break; case 2: currentState = doOtherThings; break; default: // handles numbers that not 1-4 OK printf("Invalid choice. Please try again.\n"); break; } } else { printf("HALT!"); while(1); // loop forever so serial doesn't loop menu forever // Instead need to deal with the bad character somehow }
Example shamelessly copied from here:
Code:
int main() { char i,a = 0; printf("Write something:"); scanf("%c", &i); do{ switch (i) { case '1': case '2': case '3': case '4': case '5': printf("%c",i); break; case 'e': a=1; break; default: printf("This is not a number"); break; } }while (a==0);}Statistics: Posted by jj_0 — Fri Apr 05, 2024 9:18 am
