using fgets and strcmp in C [duplicate]

Answer 1

Note two things in your code:

1. fgets keeps the trailing '\n'. the associated char in fruit should be replaced with a '\0' before comparing with the string "apple".
2. strcmp return 0 when two strings are the same, so the if clause should be changed based on what you mean.(The fruit and "apple" be equivalent in the if clause)
3. Standard usage of C main function is int main(){ return 0;}

The revised code:

#include 
#include 

char fruit[100];

int main() {
    printf("What is your favorite fruit?\n");
    fgets (fruit, 100, stdin);
    fruit[strlen(fruit)-1] = '\0';
    if (strcmp(fruit, "apple") == 0) {
        printf("Watch out for worms!\n");
    }
    else {
        printf("You should have an apple instead.\n");
    }
    return 0;
}
