Thread: Else If Statements & Conditionals

Hello, everyone! I'm new to C and am trying to make a program test certain conditions before printing certain text (see below). The question is, how and where do I add "else" statement if a user:

- Types in a number that is not in range as shown, or they type in a letter or symbol instead of a number

Obviously, my coding could be better. If there's a faster way to do what I want the program to do, then please let me know.

Any help would be greatly appreciated.

Code:

#include <stdio.h>

int main() {

int timeOfDay, skyCondition; 

printf("\nWhat time of day is it now?\n"); 
printf("1 = Morning, 2 = Noon, 3 = Afternoon, 4 = Night\n"); 
scanf(" %d", &timeOfDay); 

printf("\nWhat's the sky condition right now?\n"); 
printf("1 = Bright, 2 = Cloudy, 3 = Rainy\n"); 
scanf(" %d", &skyCondition); 

// Morning Choices
if (timeOfDay == 1 && skyCondition == 1) {
printf("\nWe recommend using the following: Morning 1\n\n”); 
}
else if (timeOfDay == 1 && skyCondition == 2) {
printf("\nWe recommend using the following: Morning 2\n\n”); 
}
else if (timeOfDay == 1 && skyCondition == 3) {
printf("\nWe recommend using the following: Morning 3\n\n”); 
}
/* else {
printf("You did not make a selection. Try again.\n"); 
} */

// Noon Choices
if (timeOfDay == 2 && skyCondition == 1) {
printf("\nWe recommend using the following: Noon 1\n\n”); 
}
else if (timeOfDay == 2 && skyCondition == 2) {
printf("\nWe recommend using the following: Noon 2\n\n”); 
}
else if (timeOfDay == 2 && skyCondition == 3) {
printf("\nWe recommend using the following: Noon 3\n\n”); 
}
/* else {
printf("You did not make a selection. Try again.\n"); 
} */

// Afternoon Choices
if (timeOfDay == 3 && skyCondition == 1) {
printf("\nWe recommend using the following: Afternoon 1\n\n”); 
}
else if (timeOfDay == 3 && skyCondition == 2) {
printf("\nWe recommend using the following: Afternoon 2\n\n”); 
}
else if (timeOfDay == 3 && skyCondition == 3) {
printf("\nWe recommend using the following: Afternoon 3\n\n”); 
}
/* else {
printf("You did not make a selection. Try again.\n"); 
} */

// Night Choices
if (timeOfDay == 4 && skyCondition == 1) {
printf("\nWe recommend using the following: Night 1\n\n”); 
}
else if (timeOfDay == 4 && skyCondition == 2) {
printf("\nWe recommend using the following: Night 2\n\n”); 
}
else if (timeOfDay == 4 && skyCondition == 3) {
printf("\nWe recommend using the following: Night 3\n\n”); 
}
/* else {
printf("You did not make a selection. Try again.\n"); 
} */

return 0; 
}

Without turning your code on its head, you might want to test the choices as the user enters them rather than waiting until the end (it's rather annoying to the user to be told the first question was answered incorrectly after he's answered additional questions)
